28 The Importance of Early Intervention for Infants and Children with Hearing Loss

detectable responses at stimulus presentation levels of 65 and 75 dB SPL in the sound field. In light sleep, no behavioral responses
were observed when broadband, low-, mid-, and high-frequency noisemakers were presented at high levels. Combining the unaided CAEP results and behavioral observations, the child
was estimated to have hearing loss of at least 80 dB HL in both ears. Accordingly, hearing aids were fitted according to the NAL prescription. After fitting, aided CAEPs were measured showing responses to /m/ and /g/, but not /t/, presented at 75 dB SPL (Fig.
28.5a). No responses were detected for any of the stimuli at lower presentation levels. The PEACH score obtained 2 weeks after the
fitting was at 2 SD below the mean of the normative population
(Fig. 28.5b). Accordingly, the hearing levels were re-estimated to profound loss, and HAs were adjusted to match revised pre­scriptive targets. Four weeks after the readjustment of hearing
aids, aided CAEPs were evaluated in the soundfield. Ear-specific aided CAEPs revealed responses to /m/, /g/, and /t/ at 75 dB SPL
in the right ear only. Middle ear problems were reported for the left ear at this time. The PEACH scores continued to show that the child’s functional performance was at 2 SD below the normative mean for his age. Speech therapists reported that the child did not show detection of the Ling sounds at 1 meter when aided, and there was no observable progress. In view of the evaluations of aided CAEPs and PEACH results and the input of the speech therapists, the family was advised to consider referral for CI candidacy evaluation before it was possible to obtain reliable results with visual reinforcement audiometry. The child received bilateral CIs by 10 months of age.
These two cases serve to illustrate a clinical management
pathway to ensure early fitting and optimizing of amplification for
individual children, and early referral for CI candidacy to ensure that a child who needs a CI gets it early. The presence of ANSD
is not a condition that precludes early amplification or cochlear
implantation. The evidence-based protocol uses a combination of objective measurement of CAEPs and behavioral assessment with the PEACH questionnaire to optimize postdiagnostic management of children with hearing loss.

preclude a child from receiving early amplication or cochlear
implantation.
28.5 Conclusion
Current evidence from the LOCHI study attests to the eective­ness of early intervention for improving outcomes of children
with hearing loss. The findings of the study can guide manage­ment of childhood hearing loss to maximize the benefit of early intervention. Following early fitting of HAs and verification of prescriptive targets, evaluation of the eectiveness of amplifica-
tion for individual children by using objective cortical measures
and the parent-report PEACH scale should be implemented. This ensures that individual progress with intervention is monitored and, if indicated, that referral for paediatric CI candidacy evalua­tion can occur at an early age.
he world for children born with PCHL has changed. With
T early detection of hearing loss and early intervention, parity of outcomes between children with hearing loss and those with typical hearing is within reach. Postdiagnostic intervention needs to be timely and to be guided by current evidence. The principle with any treatment/intervention is that we must always evaluate
its eectiveness for each individual, and if it is not eective, have
the courage to change for the better.
In summary, the presence of permanent childhood hearing loss has a negative impact on children’s developmental outcomes. The widespread implementation of UNHS makes it possible to detect

IV Educational and Clinical Management of Hearing Loss in Children

congenital hearing loss soon after birth, so treatment can begin in
infancy. However, the ecacy of early intervention for improving
outcomes has remained inconclusive. This chapter addresses
the question by drawing on findings from a population-based,
prospective study: the LOCHI study. On average, children who
received earlier fitting of HAs or CIs had better spoken language by 5 years of age. Better outcomes were also associated with less
severe hearing loss, higher nonverbal cognitive ability, absence of additional disabilities, higher maternal education level, and use of an oral mode of communication during early intervention. The LOCHI study shows that on average, the presence of ANSD did not
significantly inuence outcomes. Further, HAs that were selected according to either the NAL or the DSL prescription and verified
to match targets using real-ear measures provided adequate audibility to support language development. This chapter shows how the evidence can be incorporated in clinical management of
childhood hearing loss to maximize the benefit of early interven­tion. Current best practice includes fitting HAs in a timely fashion,
verifying that prescriptive targets are matched, and evaluating
the eectiveness of amplification for individual children by using
objective cortical measures and the parent-report PEACH scale. These processes serve to monitor individual progress with inter­vention and ensure that pediatric CI candidacy referral can occur at an early age if indicated.
Discussion Questions
1. What are some of the reasons that explain the equivocal nd-
ings in the literature on the eectiveness of early intervention?
2. Why might a longitudinal study of a single cohort over time provide stronger evidence than multiple age cohorts in exam-
ining the long-term eectiveness of early intervention?
3. What are some of the factors, in addition to age at interven-
tion, that inuence outcomes of children with hearing loss?
4. How can the clinical pathway for managing children diagnosed with hearing loss through newborn hearing screening be
streamlined to maximize the benets of early identication?
5. How might the detection of CAEPs and the use of parent-reported functional performance form part of a rou-
tine evaluation of HA tting in young children?
6. How might the detection of CAEPs and the use of parent-reported functional performance form part of stan­dard postdiagnostic management of children with ANSD?
7. Why is evaluation of HA eectiveness crucial to maximizing benets of early intervention?

Children with Hearing Loss

Advances in amplication technology and early identication
Summary
The primary objective of hearing habilitation and rehabilitation for children with hearing aids or cochlear implants is continued development of functional listening skills for spoken language learning and communication. However, without appropriately
programmed amplification devices, they will gain limited benefit from habilitation/rehabilitation eorts. This chapter
provides an overview of the systematic progression from the
fitting of amplification to the implementation of evidence-based
speech-language therapy interventions. An initial compre­hensive assessment of the child’s communicative competence is critical to identifying specific training objectives and deter­mining change over time. Recommended assessment protocols
at dierent stages of development are outlined, with particular
emphasis on the components of a functional assessment of
how the child responds to dierent types of speech stimuli, in
contrasting listening environments, which distinguishes the evaluation of a child with hearing loss from that of his or her typically developing peer with normal hearing. The remainder of the chapter addresses intervention and service delivery. Active parental involvement and close networking between home, school, and therapy should be established to reinforce listening and language targets outside of therapy. Provision of listening experiences, separate-ear and bilateral and in compet­ing background noise, is also described. The chapter concludes by discussing of how documentation from ongoing diagnostic training and regularly scheduled comprehensive assessments should direct future intervention for the individual child with hearing loss.

Key Points
The role of a speech-language pathologist encompasses
diagnostic and therapeutic responsibilities for a child who is deaf or hard of hearing. The need to assess functional listening distinguishes the
communication evaluation of a child with hearing loss from the communication evaluation of a child with normal hearing.
Audition is the most eective and ecient modality for
acquiring and monitoring spoken language skills. The primary objective of aural habilitation and rehabilitation
training is to develop functional listening skills for continued language learning and enhanced communicative interactions.
and intervention have helped more children with hearing loss to acquire functionally adequate listening and age-appropri­ate spoken language skills. Telepractice and smartphone/tablet apps support, not
replace, traditional aural habilitation/rehabilitation.
29.1 Role of the Speech-Language Pathologist
Since passage of the National Institutes of Health (NIH) Consensus Development Conference in 1993,1 most states now implement programs of universal newborn hearing screening.
As a result, hearing loss is identified at earlier ages than it was
two decades ago, and more families are seeking assessment and
treatment of the communication deficits accompanying hearing
loss by the time their infant is 1 to 3 months of age. in technology options (including digital hearing aids [HAs] and cochlear implants [CIs]), as well as the increased availability of parent-child-focused early intervention (EI) programs that emphasize auditory skill development and the comprehension
and use of spoken language, have significantly improved func­tion and performance in children with significant hearing loss.
With EI, age-level receptive and expressive communication skills
by preschool or kindergarten are expected for children identified at an early age. The positive eects of this EI place unique social
and educational management challenges on professionals and school systems alike.
It is widely accepted that a Listening and Spoken Language Specialist (LSLS), or speech-language pathologist (SLP) with training in developing listening skills, is an integral member of the interdisciplinary diagnostic team that serves children with hear-
ing loss. Traditionally, findings from an initial speech-language
evaluation yield baseline information about vocabulary, recep­tive-expressive language functioning, and speech production stimulability and capability for the child with hearing loss. These
important findings will determine initial training needs and serve as comparative data for the measurement of therapy benefit and
progress.
The communication profiles of children with any degree of
hearing loss are characterized by a wide variability in functional listening skills and linguistic competency. Therefore, for any child with hearing loss, the communication evaluation should encom­pass a functional listening assessment. This component is needed to obtain critical information about speech perception abilities
(e.g., the eect of an HA or a CI on the user’s reliance on auditory
input for continued language learning, literacy development, and enhanced communicative interactions). This functional listening assessment requirement distinguishes the speech-language assessment of a child with hearing loss from the communication assessment of his normal-hearing peers, because formulating and

implementing aural habilitation/rehabilitation training also fall within the professional domain of the LSLS or SLP.
Pitfall
Few graduate training programs oer the coursework or prac tical
experiences that are necessary to prepare the average SLP with skills to work with children with hearing loss. The academic preparation of an SLP should prepare clinicians to conduct the evaluation and treatment programs for developing auditory skills for pediatric patients with hearing loss. Furthermore, SLPs must be prepared to assume additional responsibilities for the student with hearing loss who is enrolled in general education settings (e.g., monitoring amplication, serving as a resource to the class­room teacher and to the teacher of the deaf [TOD] who may be providing preteaching of classroom vocabulary and content, and facilitating social interactions). Listening and Spoken Language Specialists do have the training to provide these services.
29.2 Diagnostic Evaluations
There are two major purposes for conducting speech-language evaluations and functional listening assessments: (1) to identify communicative strengths and weaknesses (during the initial assessment); and (2) to monitor progress over time (during prog­ress assessments). Identifying the purpose of the assessment is essential to determining the scope of the assessment and in selecting the most appropriate assessment tools.
Upon receiving a referral for evaluation, it is first absolutely
critical to review the audiologic findings and general case history.
The SLP/LSLS must understand the child’s hearing loss, including aided and unaided hearing, and be able to perform a listening check of the child’s technology to ensure that it is working and that the child has auditory access to the information presented during assessments.
Language comprehension (encompasses the assessment of the
understanding and contingent response to spoken language,
including acting on directions and questions by performing
actions, manipulating objects, pointing to pictures, or verbally
responding)
Expressive language (encompasses the assessment of non-
verbal and verbal behaviors produced to convey meaning
intentionally)
Speech production (encompasses the assessment of the artic-
ulation of speech sounds in isolation, repeated and alternated
syllables, words, and word combinations, as well as overall
voice quality, prosody, and intonational characteristics)
Pragmatic functioning (encompasses the assessment of how
spoken language is used for various communicative purposes,
such as labeling, commenting, requesting, directing, and
questioning)
Performance data yield critically needed information to deter­mine future habilitation and rehabilitation management as well as educ
ational placement and related services needs.
During the communication assessment, through formal and informal measures, the SLP or LSLS obtains information about (1)

in the performance of pediatric HA or CI users.
Testing will reveal areas that should be addressed to ensure
there is sucient and appropriate support for the child with
hearing loss, both at home and in school. Considerations such as consistency of present technology use, realistic understanding of the impact of hearing loss on language learning, and availability of
aural habilitation and rehabilitation training should be identified
during the initial diagnostic assessment. Most important, it should be possible to formulate aural habilitation and listening training objectives and strategies based on the results of a comprehensive communication evaluation.

29.2.1 Initial Assessment
Findings from an initial speech-language evaluation/functional listening assessment identify areas of strength and weakness in several skill domains, including:
Phonemic awareness (encompasses assessment of detection,
discrimination, and identification of vowel elements and consonants as they occur in isolation or in dierent positions
within words) Word recognition (encompasses comparison of open-set word
identification under separate ear and binaural listening condi­tions, in both quiet and noise)
Vocabulary (encompasses the assessment of the understand-

In contrast, subsequent assessments (routinely occurring at
6-month intervals or annually) provide all of the foregoing, but also slightly dierent information. Comparative analysis of
performance on criterion-referenced or standardized measures
aords an objective means of monitoring progress and benefit
(of both therapy and technology) for the child who is deaf or hard of hearing. Subsequent assessments also present the necessary information for making changes in the child’s aural habilitation/ rehabilitation training.

29.3 Determining the Focus of Therapy
Children enter ing the aural habi litation and rehabilit ation process fall within four major age groupings: infants, preschool-aged, school-aged, and teenagers. Each of these developmental groups
has distinctly diering diagnostic and training requirements.
Recognizing the unique needs of each group is critical both in selecting the appropriate diagnostic tools and in interpreting the
test findings and formulating appropriate training programs.
29.3.1 Infants
It is increasingly more common to be asked to conduct a speech-language evaluation and functional listening assessment on an infant who has only recently been diagnosed with hearing loss or who is just beginning an HA trial process. Because of their young ages, infants exhibit few skills that can be assessed using standard testing protocols. Therefore, a large part of the evalua­tion process involves parent questionnaires of observed auditory and basic communication behaviors. Parental responses on such questionnaires provide important information about parents’ understanding of the impact of hearing loss on future language learning and social-communicative interactions as well as par-
ents’ understanding of amplification use and aural habilitation
training on the development of desired skills.
Frequently, the infant or toddler has already undergone some type of global EI eligibility assessment. Rarely, however, has there been a systematic attempt during such assessments to observe or document the auditory responsiveness and stimulability of the
infant or toddler with hearing loss. Generic EI providers may have
limited experience with hearing loss (and even less experience in determining potential candidates for more advanced technol­ogies, such as remote microphone technology or CIs, as the child’s
primary amplification at home).
EI providers or SLPs often lack the special training or experi­ence to support the necessary preimplant training or to assist in the infant’s or toddler’s initial acclimation to either HAs or CIs. In addition, the concept of fast-tracking an infant or toddler for
implantation is often misinterpreted as aording minimal ser­vices to the child and family until an implant is fitted, when, in
fact, the early interventionist should be an active participant in preparing the baby and parents for the implant procedure.
During the HA trial, it is valuable to attempt to establish some prerequisite communication behaviors while establishing an awareness of speech and environmental sounds, such as develop­ing visual attending skills, sustained attention to sound-making toys, and exposure to a variety of low-frequency listening and vibrotactile experiences.
29.3.2 Preschoolers
The primary component of the evaluation process for the pre­school-aged child is to assess the present level of functioning in
9
light of the child’s amplification history and previously delivered
aural habilitation training. If the preschooler with hearing loss has been fortunate enough to have had some auditory-verbal training, but achieved minimal gains, the evaluator might assume that (1) the child has limited potential to use auditory input from HAs or implants that are currently being used, or (2) the technol-
ogy has not been providing sucient acoustic access to the child’s
b
rain. In contrast, if previous EI programming has been more
visually based or used sign support, one must question whether
there has been sucient focus on auditory skill emergence to determine ultimate benefit from the HA trial or implant pro-
gram (e.g., perhaps the lack of auditory progress is an artifact of
training as opposed to either a subject-specific or device-related
issue). This communication modality issue becomes particularly important in borderline cases for a CI (e.g., for children whose audiograms suggest they should be hearing better with HAs). At times, potential implant recipients might exhibit behaviors during formal testing that suggest they are more stimulable (e.g., have greater auditory potential) than reported by the parents or
their ongoing speech-language clinicians. This finding would, in
turn, suggest that changes are needed in the preschooler’s aural habilitation objectives and strategies.
Depending on the child’s age, exploration of present or future school-based aural habilitation services might also be a compo­nent of the evaluation process. When the child with hearing loss continues to exhibit limited functional listening or oral commu­nication skills, the most appropriate evaluation measures may be largely parent-report inventories or criterion-referenced assess­ment tools, keeping in mind that it is critical to include some tool to assess the nature and consistency of the preschooler’s auditory and communicative demands.
The recommended protocol for direct observation of the audi­tory skill emergence of an infant, toddler, or preschooler who is not yet talking or able to respond on formal diagnostic measures encompasses exposing the child to a range of noisemakers and speech, spanning the speech frequency range within interactive play routines. After a period of exposure, the child’s visual atten­tion should be engaged in play with an alternative manipulative toy. Then, while his visual attention is averted from the examiner,
these now “familiar” noisemakers or speech stimuli are presented, and the child’s response is observed. Specific responses could
range from stopping an ongoing action, looking up, moving rhyth­mically in response to the sound stimuli, visually scanning the environment to locate the sound source, or attempting to imitate what was heard. Having knowledge of both the acoustic features of the sounds presented as well as the normal progression for auditory skill development will enable the examiner to assess the appropriateness of the child’s observed behaviors.

29.3.3 School-Aged Children
For school-aged children, communication mode (sign language or total communication versus listening and spoken language/ auditory-verbal) and current communication skills have impact on both the diagnostic and the therapeutic management of a
child with hearing loss. Potential first-time CI candidates in this

age group are assumed to have missed the window of oppor­tunity for optimal verbal language learning (unless the referral for implantation is being made because of a change in hearing). This may create a need to assess the child’s level of linguistic
competency in her first language (e.g., a manual communication
system). In addition, when the school-aged child is being evalu­ated for implant candidacy, assessment measures should also be used to determine whether parents and professionals (who have often initiated the implant process) have realistic expectations of
the ultimate benefit for the particular implant candidate.
It is expected that the school-aged HA user or CI recipient can take formal standardized testing, preferably administered in the child’s primary mode of communication. In addition, if the present or future educational placement for this child is a regular classroom setting, it is strongly recommended that tests standard­ized on children with normal hearing be used rather than tests standardized on children with impaired hearing. This will provide a more representative sample of how the skills of the school-aged student with hearing loss compare with those of her classroom peers. The results of this evaluation are used to determine the child’s areas of strengths and weaknesses, to serve as a baseline
from which to measure future progress, and to identify specific modifications needed in the child’s ongoing aural habilitation and
rehabilitation management.
29.3.4 Teenagers
Teens and parents who enter the evaluation or rehabilitation process often do so in response to having experienced a change in hearing status or a failure in some aspect of their social-com­municative interactions. If a CI is being considered, the device may be viewed as a potential cure for deafness unless the family has been counseled adequately by hearing health care profes­sionals. Other precipitating variables for pursuing a CI in this age group, however, include obtaining a second CI or simply relaxing the criteria for implant candidacy.
The requirements of the communication evaluation for a teen­ager are the same as those for the school-aged child. However, it is also critical to involve the teen actively in the decision-making
process regarding future amplification devices (including trying
special features of a digital HA, using a remote microphone [RM] system, or obtaining a CI). Similarly, it is unrealistic to expect that any progress will be made in the recommended therapy program­ming without the teen’s motivation and commitment to such
training. If the teen has restricted language skills, it is dicult to
determine whether her limited understanding of the issues will
allow her to oer an informed consent.
Professionals who are actively involved in the diagnostic and therapy processes with teenagers recognize that teens who have adjusted to compromised auditory input over many years may perceive increased or continuous sound from more contemporary technology as bothersome and aversive. The use of social-communicative questionnaires, such as the Listening Inventory for Education (LIFE)13 or the Secondary Screening Instrument for Targeting Educational Risk (Secondary SIFTER),14
may be useful in assessing whether the teen and parents have
realistic expectations of an amplification device, the listening
environment, or present level of functioning. Similarly, sharing test results and training strategies throughout the habilitation and rehabilitation process is motivating. It also ensures that the teen maintains realistic expectations about her course of man­agement and develops a better understanding of what is needed f
or her own self-advocacy.
In recent years, there has been a growing group of children from all developmental groups who reenter the evaluation and hearing habilitation process to receive a second CI. (Special note should be made that, ideally, an HA trial has already been completed as part of the evaluation process for the second CI, involving the full-time use of an HA in the unimplanted ear.) Particularly if the teen received an initial implant at a young age, she likely has few memories of the time commitment or training required to achieve
benefit from the first device. Determining whether the teen and
family have realistic expectations for the second device (com-
pared with the dramatic gains received from the first) is a critical
component of the evaluation procedure for this group. The second implant can be expected to improve hearing in competing noise, extend distance hearing, and assist in localization. Some children
may derive little increased benefit in overall speech reception in quiet, with moderate benefits in noise. Therapeutically, the challenge lies in devising and motivating an eective protocol for facilitating integration of the dierent signals initially perceived
from each implant.
29.4 Selection of Test Protocols
The need to ensure accurate reception/perception of verbal test stimuli distinguishes the test administration for a child with hearing loss from that of her normal-hearing peers. Accordingly, all technology must be carefully checked to determine that it is functioning as intended before any speech-language-listening assessments are conducted. Assessing functional listening at the suprasegmental, phoneme, word, and sentence levels is also a necessary component of a comprehensive speech-language assessment for this population. Depending on the child’s age, selected diagnostic protocols may encompass informal and formal measures. These measures, in turn, might involve criterion-referenced or norm-referenced tools. The advantage of norm-referenced diagnostic measures is that they permit comparison of the child’s performance data to those of typically developing peers.
The components of a comprehensive communication evalua­tion should consist of three distinct skill domains: (1) auditory perception measures in contrasting listening environments; (2) receptive and expressive language functioning; and (3) speech production measures in contrasting listening environments. Table
29.115 provides an organizational framework for conducting such
an assessment. Given the wealth of available diagnostic tools, it
is clearly evident that no single test can appropriately meet the requirements of all of the necessary skill domains. A suggested protocol of tests has been included in Appendix 29.1 to oer a model for designing an appropriate diagnostic protocol.

Supplementary information may be obtained by using an assort­ment of subtests from various tests to obtain a more representa­tive sample of the child’s level of functioning and management needs, rather than using one prescribed test completely.

(Individuals with Disability Education Act) altered the delivery of services to children under the age of 3
years. The focus of such services has been modified to address
the social-communicative interactions of the child within family dynamics and daily home routines. Previously, it was not uncom­mon for an infant or toddler to be taken to a hospital or clinic setting, where frequently either the parents were not present in the session, or they passively observed the therapy session. The expectation of naturalistic EI programming is that the parents or caregivers are actively involved in the training sessions, taking conversational turns and using the clinician’s modeled tech-

unique to EI. Quite the contrary, one of the primary tenets of
the auditory-verbal and LSL approaches from their inception has been the importance of active parental involvement (see Chapters 27 and 28). Skilled clinicians within clinical settings have been able to implement naturalistic training tasks eec­tively to facilitate the child’s acquisition of a target skill (in a

less distracting environment), with active parent involvement. The expectation is that because the parents have been actively involved, they will be able to reinforce the skills within naturally occurring situations at home.
However, the mere presence of an SLP, LSLS, or early interven-
tionist disrupts the normal parent-child interactions. Parents often
express a lack of confidence in their ability to recreate modeled routines or to employ modeled strategies eectively when the
interventionist is not there. Telepractice, using Web-based tech­nology that permits two-way simultaneous communication at a distance, has the potential of ameliorating this disconnect between the parent and child with hearing loss. This service delivery option
has been suggested as a means of addressing the lack of qualified
professionals in communities with limited auditory-verbal resources.17 Telepractice also can permit the working parent or an extended family member or caregiver to be actively involved in the child’s therapy programming. Target vocabulary, concepts, and strategies can be discussed with the parents ahead of time, and via subsequent therapy sessions conducted over FaceTime or Skype, the SLP, LSLS, or early interventionist can observe and coach the parents during their interactions with the child.
Similarly, the education initiatives of the 1980s and early 1990s,
which require that the general education classroom must change to accommodate the individual learning needs of all students, has
most inuenced the delivery of support services to the student
with hearing loss, from the preschool years throughout the college experience.18 Ideally, instructional exibility should be written into the child’s Individualized Education Program (IEP), allowing for push-in and pull-out services as needed. In a push-in delivery model, the student’s auditory and speech and language training objectives are provided within the classroom setting; a pull-out
model aords training outside the classroom.
During pull-out therapy sessions, the SLP or LSLS auditory-verbal
practitioner can work in a less distracting environment on areas
of weakness that are dicult to address in a classroom setting (e.g., resolving specific phonemic confusions or addressing the
child’s preteaching needs). On the other hand, by going into the classroom environment, the clinician has the valuable opportunity to observe the imposed communicative demands and teacher-talk used by the classroom teacher in navigating the students’ behavior and to engineer social-communicative interactions between peers and adults while concomitantly addressing the child’s individual training objectives. Establishing and maintaining some form of networking between home- and school-based services could also be addressed through some form of periodic telepractice as opposed to existing speech books and emails.
Pitfalls
In all service delivery models, care needs to be taken to avoid
having the student become overly dependent upon the ser vice provider, therein fostering less independent functioning in the classroom than the student is capable of demonstrating. Familiarity or phobia regarding technology software might
discourage families to supplement face-to-face services with telepractice sessions.
29.6 Components of Hearing
Habilitation/Rehabilitation Training
In the absence of appropriately programmed HAs or CI sound
processors, limited benefit can be gained from ongoing aural
habilitation/rehabilitation. Therefore, periodic audiologic assessments are warranted to monitor the auditory status and to make changes in the device programming for a child with hearing loss.19 During the early stages of language learning, audi­ologic testing or device reprogramming is recommended every 3 months.20 However, to benefit optimally from this ongoing audiologic management, there should be an interactive exchange between the audiologist and the other clinicians working with the child.
Because the SLP or auditory-verbal therapist has many oppor­tunities to closely monitor and document the nature of the child’s phonemic confusions, she could and should share this informa-
tion with the audiologist, who can then optimize modifications
to the HA or speech processor. Current digital HAs and CI sound
processors have numerous features to enhance specific listening environments. They can be programmed with distinctly diering programs to capitalize on specific acoustic or perceptual features
to coincide with or facilitate particular training targets (see Chapters 20, 22, and 24).
Perhaps the most valuable input needed by the audiologist for device programming is a descriptive analysis of any observed positive or negative changes in the child’s auditory responsiveness reported by the clinician, including:
Tolerance to specific sounds or device settings
Attention-getting responses
Distance listening
Phonemic confusions
29.6.1 Therapy Environment
The optimal listening and learning environment for any child
acquiring language is a quiet, child-friendly setting that aords a
variety of sensory experiences and permits independent explora­tion. The structured auditory therapy session can occur within a range of environments from natural home environments to quiet or noisy classroom settings or acoustically controlled clinic set­tings, depending on the purpose of the therapy session. It seems counterintuitive to attempt to facilitate critical listening in a distracting environment with competing background noise; how­ever, this may be the purpose of an advanced listening session.
Equally as critical is that auditory therapy should be a parent-child directive (e.g., actively involving the parent or care­giver in the ongoing training tasks). Regardless of the frequency of training sessions, it is indisputable that the parents will be the most consistent source of auditory and speech-language stimu­lation to the child. It is, therefore, essential to guide the parents in acquiring skills and strategies for eliciting their child’s optimal listening, comprehension, and production responses within natu­rally occurring daily routines.
