Question 1

Which type of assistive listening system uses electromagnetic induction to transmit audio signals directly to a telecoil in a hearing aid?

Accepted Answer

Induction loop system

Answer

Induction loop (hearing loop) systems create an electromagnetic field that is picked up by the telecoil (T-coil) in hearing aids and cochlear implant processors.

Question 2

An FM assistive listening system operates by transmitting audio using which technology?

Accepted Answer

Radio frequency signals

Answer

FM systems transmit audio via radio frequency signals from a transmitter (worn by the speaker) to a receiver worn by the listener.

Question 3

Which assistive listening device (ALD) is most susceptible to interference from other light sources such as fluorescent lighting?

Accepted Answer

Infrared system

Answer

Infrared systems transmit audio using invisible light waves and can be disrupted by other infrared sources, including fluorescent lighting and sunlight.

Question 4

A patient with a severe-to-profound hearing loss reports difficulty using the telephone even with hearing aids. The MOST appropriate assistive technology to recommend first would be:

Accepted Answer

A captioned telephone (CapTel)

Answer

A captioned telephone displays real-time captions of spoken words, making telephone communication accessible regardless of residual hearing ability.

Question 5

The Americans with Disabilities Act (ADA) requires that places of public accommodation provide effective communication. Which assistive listening system is specifically mandated in many large assembly areas under ADA guidelines?

Accepted Answer

Hearing loop or FM system

Answer

ADA guidelines require assistive listening systems (such as hearing loops or FM systems) in assembly areas with audio amplification, ensuring access for people with hearing loss.
