Hearing Loss Hearing Loss Prevention Test 2

Question 1

Which test is typically used in newborn hearing screening programs?

Accepted Answer

Otoacoustic emissions (OAE) and/or auditory brainstem response (ABR)

Answer

OAE and ABR tests are used in newborn screening because they are objective, non-invasive, and can be performed on sleeping infants without requiring a behavioral response.

Question 2

Noise-induced hearing loss is considered preventable because it is caused by:

Accepted Answer

Controllable environmental noise exposures that can be reduced or blocked

Answer

NIHL is entirely preventable because it results from environmental noise exposures that can be controlled through engineering controls, administrative controls, and hearing protection.

Question 3

The hierarchy of controls for occupational noise hazards places which control method as most effective?

Accepted Answer

Engineering controls (noise source reduction)

Answer

Engineering controls are the most effective in the hierarchy, addressing noise at the source (e.g., quieter machinery, enclosures, vibration dampening) rather than relying on human behavior.

Question 4

Annual audiometric testing in workplace hearing conservation programs is intended to detect:

Accepted Answer

Standard threshold shifts (STS) indicating noise-induced hearing damage before it becomes severe

Answer

Annual testing detects standard threshold shifts (a 10 dB or greater average shift at 2000, 3000, and 4000 Hz) early, allowing intervention before hearing loss becomes significant.

Question 5

Recreational noise exposures that can cause hearing loss include which of the following?

Accepted Answer

Concerts, power tools, and personal audio devices at high volumes

Answer

Concerts, power tools, and personal audio devices at high volumes all exceed safe noise levels and are among the leading causes of recreational noise-induced hearing loss.
