Audiometric Testing: 29 CFR 1910.95(g)(h)

The audiometric testing is to determine the presence of a Standard Threshold Shift (STS) or change in hearing when compared to the employee’s baseline. A STS shift is a shift in hearing of 10 dB average or more at 2000, 3000 and 4000Hz in either ear compared to baseline. Below are our offered services:

Baseline Audiogram:

Audiometric baseline testing must be performed on all employees whose exposures equal or exceed, OR would be expected to equal or exceed the Action Level within six months of an employee’s first exposure at or above the Action Level.

All employees who have not previously had a baseline audiogram during their employment shall be provided with an audiometric baseline test prior to being assigned to a high noise area.


Annual Audiogram:

Annual audiometric testing must be made available to all employees exposed to 85 dBA TWA (Action Level). Testing must be performed by a professional or qualified technician.


Problem Audiogram Review:

Problem audiograms must be reviewed by an audiologist, otolaryngologist or physician according to OSHA.

Employer Information:

If a Standard Threshold Shift has been identified, the employee must be notified in writing within 21 days.

An STS must be recorded on the OSHA 300 log of work related injuries under the column for hearing loss.
