Hearing Aid Fitting & Adjustment Flashcards

During a follow-up appointment, a patient reports the hearing aid is comfortable in quiet but causes listening fatigue in noisy restaurants. Which feature adjustment is most appropriate?

Answer: Activate or strengthen directional microphone processing in the noise program

Directional microphone technology attenuates signals from the sides and rear, improving signal-to-noise ratio in noisy environments and reducing listening fatigue.

Which of the following best describes 'extended wear' hearing aids such as Lyric?

Answer: Devices placed deep in the canal by a clinician and worn continuously for weeks

Extended-wear hearing aids are placed deep in the ear canal by a trained provider and worn continuously, including during sleep and showering, for several weeks at a time.

A patient's aided speech recognition score (word recognition) does not improve significantly after fitting. What is the most appropriate next clinical step?

Answer: Re-evaluate the audiogram and consider referral for further medical evaluation

Lack of benefit may indicate retrocochlear pathology, reduced auditory processing ability, or inaccurate audiometric data, warranting re-evaluation and possible medical referral.

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

Answer: To pick up electromagnetic signals from loop systems and compatible telephones

The telecoil picks up electromagnetic fields generated by induction loop systems and telephones, providing a cleaner signal by bypassing the microphone.

Which term describes the gradual increase of hearing aid gain over the first few weeks of fitting to help a new user adapt to amplification?

Answer: Acclimatization or adaptation management

Acclimatization (adaptation management) intentionally starts at reduced gain and increments it over time so new users can comfortably adjust to amplified sound.

A hearing aid earmold with a #13 sound bore and no vent is most appropriate for which type of hearing loss?

Answer: Profound flat hearing loss

A standard bore with no vent maximizes low-frequency retention and prevents feedback, making it suitable for severe-to-profound flat losses that require maximum gain.

When counseling a first-time hearing aid user, which realistic expectation should be set regarding background noise?

Answer: Hearing aids improve speech understanding in noise but do not eliminate it

Even with advanced noise reduction, hearing aids improve but do not eliminate background noise, and setting this expectation prevents disappointment and improves adherence.
