IHS Instrument Selection 4

Question 1

When fitting hearing instruments for a professional musician, which consideration is MOST critical during instrument selection?

Accepted Answer

Ensuring the instrument handles high SPL input without distortion and includes a music program

Answer

Musicians require instruments that process high sound pressure levels without distortion and benefit from dedicated music programs with different compression settings than speech programs.

Question 2

An elderly patient who lives alone reports difficulty hearing smoke alarms. Which recommendation is MOST appropriate?

Accepted Answer

Recommend alerting assistive devices such as vibrotactile or visual alarms in addition to hearing aids

Answer

Alerting devices such as bed shakers or strobe alarms supplement hearing aids to ensure safety for critical environmental signals, especially during sleep.

Question 3

Which factor is MOST important when selecting a hearing instrument for a 3-year-old child?

Accepted Answer

Safety features including tamper-resistant battery doors and pediatric earmolds

Answer

Pediatric instruments must include tamper-resistant battery doors to prevent battery ingestion and allow appropriate gain for consistent auditory access during language development.

Question 4

A patient works outdoors in varying weather. Which instrument characteristic should be PRIORITIZED during selection?

Accepted Answer

High IP (Ingress Protection) rating for moisture and dust resistance

Answer

A higher IP rating (e.g., IP67 or IP68) ensures the instrument resists damage from water ingress and dust exposure common in outdoor work environments.

Question 5

A patient has unilateral profound sensorineural hearing loss with normal hearing in the opposite ear. Which fitting approach is MOST appropriate?

Accepted Answer

A CROS or BiCROS system

Answer

CROS systems route sound from the non-aidable ear to the normal or better-hearing ear, allowing the patient to hear sounds originating from their deaf side.
