Study Notes
FM Systems Overview
- An FM system consists of three key components: a microphone, a transmitter, and a receiver with a transducer.
- Signals are transmitted directly from the speaker's microphone to the transmitter, which sends the signal to the recipient's hearing aid, cochlear implant, or BAHA.
Purpose of FM Systems
- Most beneficial when the audio source is singular (e.g., a teacher speaking).
- Effective in environments such as classrooms, business meetings, and museum tours.
- Provides sound directly to the user, irrespective of distance, enhancing speech recognition by up to 30%.
Benefits of FM Systems
- Deliver signal level improvements of 15-20 dB, enhancing signal-to-noise ratio (SNR).
- Increase speech clarity and audibility, aiding language development and comprehension.
- Foster better attention spans, sound awareness, and discrimination.
- Used extensively in educational settings for years, contributing to academic success.
Ear Level FM Receivers
- Ear-level FM receivers allow the transmission of sound from the FM transmitter to the user’s hearing device via radio frequency.
- The wireless connection is established when both transmitter and receiver are powered on.
- An adaptor connects the ear-level receiver to the sound processor, facilitating seamless communication.
Neckloop FM System
- The neckloop serves as a receiver, utilizing the sound processor's telecoil to capture the magnetic field.
- This setup is favored among many cochlear implant users for its effectiveness.
Soundfield FM Systems
- Assistive listening devices amplify the teacher’s voice in classrooms, protecting vocal health and improving student access to spoken words.
- Adapt to background noise levels, enhancing speech intelligibility dynamically.
- Approximately 160,000 classrooms in the U.S. utilize soundfield systems, benefiting both hearing-impaired and typically hearing students.
Phonak Receivers
- Phonak offers universal and design-integrated receivers compatible with their hearing instruments.
- Receivers cater to a wide range of users, including those with normal hearing and cochlear implant users.
Classroom Environment Modifications
- Adjust seating arrangements and chair types; introduce carpets, drapes, and sound-absorbent materials.
- Utilize FM systems, adjust instructor positioning and speaking methods, and provide interpreters when needed.
- Implement supportive strategies, such as a buddy system, cueing, and repeated instructions, supplemented with written materials and demonstrations.
Social Modifications in Classrooms
- Encourage sign language usage alongside oral communication for inclusive learning.
- Position hearing students in ways that facilitate peer interaction.
- Directly instruct on social skills and create cooperative learning experiences between deaf and hearing students.
Behavioral Modifications in Classrooms
- Clearly display expectations and rules to guide student behavior.
- Utilize interest inventories to tailor positive reinforcements and identify areas of improvement.
- Engage in regular feedback, implement home/school contracts, and use behavioral contracts to manage conduct and support student development.
- Introduce structured environments to minimize distractions and encourage positive interactions among students.
