Hearing Loss Hearing Aids and Assistive Devices Test 2

Question 1

FM systems used in classrooms work by:

Accepted Answer

Transmitting the teacher's voice directly to the student's hearing device via radio frequency

Answer

FM systems use radio frequency transmission to send the speaker's voice directly to the listener's hearing device, reducing the impact of distance and background noise.

Question 2

A bone-anchored hearing aid (BAHA) is best suited for patients with which type of hearing loss?

Accepted Answer

Conductive or mixed hearing loss with ear canal abnormalities

Answer

BAHA devices bypass the outer and middle ear by conducting sound through bone directly to the cochlea, making them ideal for conductive/mixed hearing loss or when ear canals are absent or blocked.

Question 3

What does 'open fit' refer to in modern hearing aid technology?

Accepted Answer

A fitting where the ear canal is not fully occluded, allowing natural low-frequency sounds in

Answer

Open-fit hearing aids use a small dome or vent that leaves the ear canal mostly open, preventing the occlusion effect and allowing natural sound to enter alongside amplified sound.

Question 4

Directional microphone technology in hearing aids primarily helps users:

Accepted Answer

Focus on sounds coming from in front while reducing sounds from behind

Answer

Directional microphone systems improve speech understanding in noise by focusing amplification on sounds in front of the listener and attenuating noise coming from other directions.

Question 5

The occlusion effect in hearing aids refers to:

Accepted Answer

A hollow or booming quality in one's own voice caused by a blocked ear canal

Answer

The occlusion effect occurs when a hearing aid or earmold blocks the ear canal, causing low-frequency bone-conducted sounds (like one's own voice) to resonate and sound hollow or boomy.
