Hearing Loss Hearing Aids and Assistive Devices Test 1

Question 1

Which hearing aid style sits entirely within the ear canal and is the least visible?

Accepted Answer

Completely-in-canal (CIC)

Answer

Completely-in-canal (CIC) hearing aids are the smallest and least visible style, fitting entirely within the ear canal.

Question 2

A behind-the-ear (BTE) hearing aid is typically recommended for which patient population?

Accepted Answer

Children and those with severe to profound hearing loss

Answer

BTE hearing aids are recommended for children because they can be reprogrammed as needs change, and for those with severe to profound hearing loss due to their greater amplification capacity.

Question 3

What is the primary function of a telecoil (T-coil) in a hearing aid?

Accepted Answer

To pick up electromagnetic signals from loop systems and telephones

Answer

A telecoil picks up electromagnetic signals from telephone handsets and hearing loop induction systems, improving hearing in compatible environments.

Question 4

Receiver-in-canal (RIC) hearing aids differ from traditional BTE aids in that the receiver (speaker) is located:

Accepted Answer

Inside the ear canal

Answer

In RIC hearing aids, the receiver is placed directly in the ear canal, connected to the behind-ear unit via a thin wire, which reduces feedback and improves sound quality.

Question 5

What does 'feedback' refer to in the context of hearing aids?

Accepted Answer

Amplified sound leaking back into the microphone causing a whistling sound

Answer

Hearing aid feedback is a high-pitched whistling or squealing caused when amplified sound from the receiver leaks back into the microphone and is re-amplified.
