Question 1

A Bluetooth-enabled hearing aid connects to smartphones primarily using which Bluetooth protocol optimized for audio streaming to hearing aids?

Accepted Answer

Bluetooth Low Energy (BLE) / LE Audio

Answer

Modern hearing aids use Bluetooth Low Energy (BLE) and the newer LE Audio standard to stream audio efficiently with minimal battery drain.

Question 2

When recommending a hearing loop system for a patient's home television viewing, the hearing instrument specialist should verify that the patient's hearing aids have which feature enabled?

Accepted Answer

Telecoil (T-coil)

Answer

A hearing loop system transmits via electromagnetic induction that is only detected by the telecoil (T-coil) in hearing aids; this feature must be present and activated.

Question 3

Which type of closed captioning service provides real-time captions transcribed by a trained stenographer for live events?

Accepted Answer

CART (Communication Access Real-Time Translation)

Answer

CART uses trained stenographers to produce real-time verbatim captions during live events, achieving higher accuracy than automated ASR alone.

Question 4

A remote microphone (RM) accessory used with hearing aids primarily improves which aspect of hearing in noisy environments?

Accepted Answer

Signal-to-noise ratio (SNR)

Answer

Remote microphones transmit the speaker's voice directly to the hearing aids, dramatically improving the signal-to-noise ratio by placing the microphone close to the sound source.

Question 5

An infrared assistive listening system is MOST suitable for which environment?

Accepted Answer

Indoor meeting rooms requiring confidentiality

Answer

Infrared signals cannot pass through walls, making infrared systems ideal for confidential settings such as courtrooms and boardrooms where signal security is important.
