Hearing is an important sense for Learning
• Parents and teachers capitalize on this – using the auditory-oral communication mode as the primary approach in the majority of learning situations
• In our communication we engage in small talk, fiery discussions, romantic discourse, philosophy & politics,…
• This emphasis on listening can pose difficulties for those who cannot use this information successfully
Information carried from the ear to the brain must be of high fidelity
or the information available to the listener will be faulty
![Page 5: Advances in FM Technology Improving Performance in APD Miranda Weidle, MS Pediatric and FM Specialist.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649e4f5503460f94b46272/html5/thumbnails/5.jpg)
Sometimes people lose high-fidelity listening – despite normal hearing thresholds…
• Auditory Processing Disorder• Attention Deficit/Hyperactivity Disorder• Specific Learning Disability• Multiple Sclerosis• Non-native speakers• Sensory Processing Difficulties, e.g. Asperger‘s syndrome,
Autism Spectrum Disorder, Sensory Integration Disorder• Speech-Language Disorder• Cerebral Palsy• Traumatic Brain Injury
![Page 6: Advances in FM Technology Improving Performance in APD Miranda Weidle, MS Pediatric and FM Specialist.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649e4f5503460f94b46272/html5/thumbnails/6.jpg)
…or near-to-normal hearing thresholds…
• Unilateral Hearing Loss• Slight Hearing Loss• Permanent Conductive Hearing Loss• Fluctuating Conductive Hearing Loss• High-frequency Hearing Loss• Auditory Neuropathy/Dys-synchrony

Children are more at risk than adults in the presence of background noise
• Children bring a different listening to a learning or communicative situation
• Background noise masks speech and reduces speech quality
• Understanding speech means that we combine what we hear with what we know
• The auditory system doesn’t mature until the age of 16• Children don’t have the language and life experiences
adults use to fill in gaps
![Page 8: Advances in FM Technology Improving Performance in APD Miranda Weidle, MS Pediatric and FM Specialist.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649e4f5503460f94b46272/html5/thumbnails/8.jpg)
An Auditory Processing Disorder
• Affects the efficiency & precision with which we handle auditory system, primarily in the central auditory system
• 3-5 % of all children (Musiek, 1997)
• 2 times more boys than girls
• Many different possible causes
![Page 9: Advances in FM Technology Improving Performance in APD Miranda Weidle, MS Pediatric and FM Specialist.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649e4f5503460f94b46272/html5/thumbnails/9.jpg)
Identification Process
• Electrophysiologic Tests• Behavioral Test Monaural Low-Redundancy Speech Tests • Dichotic Speech Tests
– Dichotic digit test• Temporal Patterning Tests
– Frequency pattern sequences test– Binaural Interaction Tests
• Rapidly Alternating Speech Perception
(Schminky & Baran, 1999)

Audiologists can offer
• Direct remediation therapy
• Compensatory strategies
• Environmental modifications

Use of an FM system
• Considered a corner-stone intervention
• It gives the listener an upfront & high-quality access to the speaker‘s voice
• Listeners can focus on content
![Page 13: Advances in FM Technology Improving Performance in APD Miranda Weidle, MS Pediatric and FM Specialist.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649e4f5503460f94b46272/html5/thumbnails/13.jpg)
Evidence shows a clear FM benefit for children with learning difficulties
• Increased attention• Optimal spoken language understanding• Higher academic achievement• More consistent on-task behavior• Maximum speech understanding in noise• Improvement in classroom behavior• Important for long-term benefits: having children tune in
again

![Page 22: Advances in FM Technology Improving Performance in APD Miranda Weidle, MS Pediatric and FM Specialist.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649e4f5503460f94b46272/html5/thumbnails/22.jpg)
Dynamic Speech Extractor Voice Activity Detector
VAD in the transmitter mutes the receiver when the speaker stops talking
•Benefit 1: ambient noise is not amplified during speech pauses
•Benefit 2: FM channel noise is not audible when the receivers are silent
![Page 23: Advances in FM Technology Improving Performance in APD Miranda Weidle, MS Pediatric and FM Specialist.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649e4f5503460f94b46272/html5/thumbnails/23.jpg)
Dynamic Speech ExtractorEasy Adjustment of FM Advantage

Datalogging FMProviding comprehensive insight
• DataLogging FM data is accessible from FM SuccessWare 4.0 onwards, so only to the audiologist/FM fitter
• DataLogging FM enables the fitter to give excellent support to FM users and their environment (parents, teachers, partner, friends)
• DataLogging FM saves teachers to take notes when something happens
• DataLogging FM provides detailed insight in the FM system‘s performance and use over time
