Medical interpretation and diagnosis from audiometric results is beyond OHC scope and must be performed by a licensed audiologist or physician.

What type of audiometric test is an OHC primarily trained and authorized to perform?

Answer: Pure tone air conduction audiometry

OHCs are specifically trained in pure tone air conduction audiometry, which is the standard method used in occupational hearing conservation.

Before a baseline audiogram, the worker must observe a quiet period of at least how many hours to ensure valid results?

Answer: 14 hours

OSHA requires at least 14 hours away from noise exceeding 80 dBA before baseline audiometric testing to prevent temporary threshold shifts.

What is the correct daily procedure an OHC should perform to verify audiometer calibration before testing workers?

Answer: Conduct a biological check with a person of known stable hearing thresholds

A daily biological calibration check using a listener with a known stable audiogram verifies that the audiometer is producing reliable results.
