Determining Need and Benefit of FM Use: Measurement of Outcomes Shortened Handout Version. Karen Anderson, PhD [email protected]. Many new challenges in pediatric audiology. Probe microphone measurements - PowerPoint PPT PresentationTRANSCRIPT
Karen Anderson, PhD
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.
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
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
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
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
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
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
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
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
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
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
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
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
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.
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
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
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
Interview format – 10 questions for parent to answer
Oriented to speech use and intelligibility Good format for discussion Good back-up if family does not follow through
completing the ELF Also available: MAIS and MUSS
◦ Advanced Bionics – call customer service to request copies
Takes over where the ELF begins Assesses the functional auditory skills within a
sequence of development – not just detection Each skill rated as not present, emerging, in
process, or acquired Could be an integrated part of early intervention;
assistance to parents in observing and completing Update on a regular basis (i.e., monthly)
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
Available from Oticon 3 worksheets: child’s needs, parent’s needs, teacher’s
needs 3 or 4 very general situations with blanks to add 1 or 2
more situations Judgment is made “Because of the new hearing
instrument, I now hear…’ Second judgment is made “I can hear satisfactorily, 10-
95% of the time”
For ages 3 years to approximately 12 years (plays with others, not parallel play)
Provides 15 listening situations typical of the home environment
Understand-o-meter 2 Forms:
◦ Parent completes items◦ Child completes items (age 7-8+)
Can compare parent and child responses; use as a means to discuss need for home FM, assistive devices, changes in family communication dynamics
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
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
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
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
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
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”
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
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?)
Preschool SIFTER – age 3- kindergarten SIFTER – grade 1 – grade 5 / 6 Secondary SIFTER grade 6-12 CHAPS – kindergarten – grade 5 / 6OTHER BROADBASED SCALES Psychological Scales: Social Emotional Function
◦ Behavior Assessment System for Children◦ Achenbach Scales (Teacher Rating Form)◦ Burk’s Behavior Rating Scale◦ Connors’ Rating Scale◦ Behavior Evaluation Scale
Listening Instrument For Education Collects information on child’s function with and
without amplification (hearing aids, new hearing aids, CI, FM, compare FM types) and indicates need for accommodations (504)
Student LIFE – self report; grade 3+ Teacher LIFE – pretest and post-test
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
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
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
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.
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
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
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
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
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).
