Probe microphone measurements Using electrophysiological data to infer hearing

thresholds for early hearing aid fitting Hearing aid fittings on babies 1-3 mos old! Fitting programmable and digital hearing aids

rather than familiar analog aids Letting go of relying on behavioral measures of

hearing until a child is 5-6 months old Etc.

Page 3: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Match the gain and output to DSL targets Earmolds fit snugly so no feedback Parents understand that they need to return for

new earmolds when feedback occurs Parents have been instructed in earmold insertion

and the care and operation of the hearing aids◦ THESE ARE ALL THINGS THAT THE AUDIOLOGIST DOES

Page 4: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

The child wears the hearing aids consistently!

Parents make an appointment for new earmolds as soon as they notice feedback

Parents have a real understanding of the child’s hearing loss and its affects

Page 5: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

TRY TO DO1. Talk about how the hearing

loss affects speech perception

2. Describe hearing in terms of daily listening situations (listening range, communication access)

3. Encourage parents to observe their child’s responses to sound

AVOID1. Describing hearing loss

by using labels (mild, moderate, Deaf, HOH)

2. Teaching parents about the audiogram, they can learn it later

3. Giving the impression that amplification will fully take care of the child’s hearing problems

Page 6: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Slight Hearing Loss or Unilateral Hearing Loss◦ May miss some consonants; mild difficulty with auditory language

learning, listening at a distance and in noise Mild Hearing Loss

◦ Only hears louder speech sounds; difficulty with auditory learning, some speech/language delays, inattention

Moderate Hearing Loss◦ Hears almost no speech sounds at normal levels; articulation

differences, language delay, learning dysfunction related to language delays, inattention

Assume communication from 6 feet

Page 7: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Severe Hearing Loss◦ Hears no speech sounds at normal levels; very

reduced speech intelligibility, verbal language delay, learning dysfunction related to language delay, inattention to verbal communication

Profound Hearing Loss◦ Hears no speech or other sounds; little or no

speech intelligibility, little or no verbal language, learning dysfunction related to language delay, learns by visual cues or manually coded language systems, inattention to verbal communication

English and Spanish handouts at: www.kandersonaudconsulting.com Hint: use to help describe effect of hearing loss in

reports, parent counseling, teacher inservice

Page 9: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

True management of hearing loss goes beyond diagnosis and hearing aid fitting

Interpreting hearing loss in a way that the parent can integrate the knowledge into their daily lives and share it with other people who care for the child

Ongoing consultation, information, support to the family

Listening NOT advising

Page 10: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Buy-In or recognition that:

The hearing loss is It WILL affect the child’s development if it is not addressed Communication access is JOB #1 in preventing delays from

developing They – the daily caregivers – are the people who must be

involved most in helping their child learn language --- parents are the magic

The prognosis for normal or near-normal development is good but it requires their investment of time and energy

Page 11: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

1. Suggest some ways in which people who work with children with hearing loss can involve parents so that they will develop a higher level of buy-in

2. Discuss ways in which we can validate the degree of benefit experienced with their choice or adjustment of hearing instrument

3. Discuss birth to five, but also present tools for school-age and adolescents when teacher buy-in is critical to the child’s success

Page 12: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

The key to successful development and learning is effective access to speech from as early as possible

Regular screening of functional ability in typical environments assures that children will not develop or increase gaps in learning

School accommodations, including FM, are necessary to maximize learning and performance in school

The ‘age of accountability’ requires documentation beyond the audiogram to support a child’s need for S/N enhancing technology

Page 13: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Test instruments involve the parent or teacher in thinking about the child’s behavior and making a judgment

By involving them we are showing that we respect their opinion – that they have valuable insights to offer

Auds set hearing aids for audibility of speech at different levels of input but people who are with the child everyday observe his or her functional use of hearing

Page 14: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Hearing loss and audiograms do not make much sense to most people, especially soon after a diagnosis

Parents cry and then go home and bang pots Audiologists can recognize the parent’s need to

understand the hearing loss in terms of the child’s listening/communicating at home

We need to ask parents to participate in the discovery process to foster their understanding and buy-in to the diagnosis and amplification use

Page 15: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Educational audiologists are not in all school districts and often are not involved at length with any one child

Use of instruments completed by parents and teachers is more efficient and may provide valuable and different information than obtaining full academic assessment

Parents involved early in recognizing their child’s hearing needs have the power to influence their educational program

Page 16: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

ELF Early Listening FunctionWhy: Hearing is a distance sense. A child with a hearing loss will have a reduced hearing range, or a smaller listening bubble, than a child with normal hearing. Audiologists test to find out what tones a child can detect, but only someone who is with the child for hours everyday can observe how the child is using hearing in daily situations. Hearing instruments will improve the size of the listening bubble. With use of amplification during all waking hours, auditory skills will usually improve over time.

Page 17: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

6 inches, 3 feet, 6 feet, 10 feet, 15+ feet 12 Activities:

• 4 quiet, 4 typical loudness, 4 loud Loudness calibration is not critical – parent participation

in typical environments is critical Quiet and noise: develop awareness of how having the

TV always on limits the child’s perception of other sounds

Page 18: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Gives the parents something “to do” to feel like they are helping their child

Can be a first activity with early intervention Motivating for following through with hearing aids or new

earmolds Tuning into auditory development over time Involve all caregivers Provides parents with a clear way of

describing the hearing loss

Page 19: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Each activity has a point value do a possible score out of 100 can be obtained

Audiologist scores and compares over time Reveals improvements in perception of quiet

input or across distance Separate form for parents to complete 1-2

weeks after new amplification is fit May be beneficial to family compliance

(Example: Dad’s who get involved in ‘measuring’)

Parents circle 1-5 scale: Agree, No Change, or DisagreeMy child appears to: 1. Be more aware of my voice2. Be more aware of environmental sounds 3. Search more readily for the location of my voice 4. Have an increased amount of babbling or talking 5. Have more interest in communicating During ELF listening activities, the size of my child’s listening bubble:1. Has improved for quiet sounds voices 2. Has improved for typical sounds and voices 3. Has improved for loud sounds and voices 4. Has improved for listening in background noise Describe specific situations when you noticed improvements in listening

Developmental sequence of listening skills for children with normal hearing

Helpful for parents of children with “little hearing losses”

Underscores that children’s listening skills aid in the development of socialization and verbal development

The following instruments can be used to:◦ Involve the parent or teacher to improve buy-in and

understanding of the child’s abilities and need for accommodations

◦ Screen classroom performance to determine if educational assessment, change in services or accommodations need to be considered

◦ Provide an indication of the need for a trial period with a personal FM system or other assistive devices

◦ Provide a pre-test/post test format following implementation of FM, new hearing instruments, improved accommodations

FEW – Family Expectation Worksheet◦ Child is successful in this situation…◦ Parents list goals in order of priority◦ Rate the level of child’s success (pre/post-test)

Pediatric Hearing Demand, Ability, and Need Profile◦ Descriptions of communication activities◦ Parents rate if a communication problem is present if the hearing

aid is on or off◦ Parents check if problem is due to hearing, noise, distance,

visibility and the current compensation

Page 28: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Typically a child will enter preschool or kindergarten and the educational audiologist or speech language pathologist may be informed that they have a hearing loss or hearing aids

Their role is to make recommendations on if the child requires any accommodations to be able to access verbal instruction

Page 29: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Increasingly, children with hearing loss are in full-time regular education settings

504 accommodations are often more difficult to obtain than special education services from an education specialist

Children with hearing loss will continue to require acoustic accommodations, regardless of their early intervention successes

Parents who are knowledgeable of their child’s auditory needs and who have the documentation to advocate for appropriately intense accommodations are empowered

If a school does not provide accommodations and the child’s performance decreases over time, the school could potentially be held liable for providing insufficient accommodations

Page 30: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Acoustic signals degrade with distance Integrity of the speech signal is compromised by

background noise and reverberation typical of classrooms

Children with auditory disorders are at greater risk for speech perception difficulties under adverse listening conditions

FM technology addresses conditions of distance and background noise and provides benefits to speech perception of the primary signal for persons with normal and impaired hearing

Page 31: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Ignorance by school administrators of FM Concern over school budgetary expense Only required to provide an appropriate program, not

the most appropriate Aim is for “average” achievement (within the range of

the classroom), not optimal Definition of “need” for FM – varies widely

Page 32: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Quoting research helps get the attention of teachers and administrators but is not child specific

Looking at academic grades or asking the teacher or parent “how the child is doing” is too vague

The audiogram does not provide a complete picture of a child’s speech perception, listening in noise abilities, and coping skills

Speech in noise tests in the sound suite provide a 2-dimensional indication of speech perception, functional listening evaluation is more “realistic”

Page 33: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

How well does the child perform in different typical communication situations◦ Verbal instruction◦ Class discussion◦ Peer conversations ◦ Home situations◦ Quiet and noise◦ Relatively near and far

Page 34: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

PURPOSECompare students functioning to peers

(Is there a functional deficit in any area?)Determine areas of non-strength (Based on these, what

accommodations or assessments are indicated?)Monitor functioning over time (Do the

accommodations/services meet the child’s speech perception needs and deficit areas so that level of functioning is improved/maintained?)

Determine degree of benefit of classroom technology on overall function after an extended period of use (Are there improvements?)

Observation study performed in the classroom: time on task without amplification device and again when student is using device of interest

Functional Listening Evaluation with and without device of interest

Teacher observation of following typical directions in the classroom setting

Word discrimination in classroom◦ Spelling tests◦ Wepman Auditory Discrimination Test◦ California Consonant Test in classroom

Page 38: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

TEAMS make decisions on children’s needs based on information

The more compelling and reality based the information the better the chance that appropriately intense accommodations will be provided for the child

Documenting auditory needs related to noise and distance early will create valuable track record supporting avocation

Page 39: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Defined procedure to determine how listening abilities are affected by noise, distance, and visual input

Not a sound booth test; done in a “typical environment”

Verbal language response required; 3-word sentences (common phrases and nonsense phrases)

8 lists of words or phrases needed Can use to show benefit of any type of FM use A “staple” in educational audiology

Page 40: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

The SIN Test audio compact disk is required for test administration.

On this CD, test sentences were recorded at "soft" and "loud" levels 30 dB apart.

Each of these levels is presented at four signal-to-noise ratios (SNRs) with multi-talker babble as the background noise.

Page 41: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

An intense look at auditory attention Difficult and time consuming for teacher (or parent)

to complete, but good information Especially useful for obtaining indepth information

on children with unilateral, minimal, mild, or cookie-bite hearing loss

Scoring grid shows abilities that fall into normal and at-risk performance categories

Can do following a trial period with sound field amplification in the classroom or personal FM use at home/school

Page 42: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

To be completed by the preschool teacher Teacher must be aware of what is developmentally

normal for the child’s age 15 questions: preacademics, attention,

communication, class participation, school behavior Scoring: pass or at-risk for expressive communication

or socially appropriate behavior

Page 43: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Very similar to Preschool SIFTER 15 questions, 5 content areas Scoring grid results in pass, marginal or fail Valuable for parents of children with hearing loss who are

concerned about school progress; audiologist can assist them in determining if concern is warranted

Parent can bring to teacher and return to audiologist (or provide SASE)

Recommendations for FM can be made based on SIFTER results

Valuable to use May SIFTER to inservice new teacher in September

15 common school listening activities Best for elementary, but can use in secondary Student appraisal: child judges if a listening situation

is always easy, mostly easy, sometimes difficult, mostly difficult, or always difficult

Page 45: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

Pretest (or any time) and Post-test following trial with a new or adjusted amplification device (any type of FM, digital aids after having worn analog)

15 common classroom situations Teacher rates student’s apparent degree of listening

challenge in the different situations Total appraisal score plotted on a continuum

Page 46: Determining Need and Benefit of FM Use: Measurement of  Outcomes Shortened Handout Version

By the time a child is about 10, they should be fully independent with checking their hearing aids and advocating for classroom accommodations

The LIFE provides a format for the child to develop an awareness of how classroom environments affect listening and understanding and what he or she should do to make it better

Secondary SIFTER can screen for functional classroom performance

Even students who are academically successful are entitled to 504 accommodations such as written assignments, appropriate acoustics, seating, FM, etc).
