The baseline audiogram is the first and referenced audiogram against which future audiograms are compared. Employers must provide baseline audiograms within 6 months of an employee’s first exposure at or above an 8-hour TWA of 85 dB. An exception is allowed when the employer uses a mobile test van for audiograms. In these instances, baseline audiograms must be …

A baseline audiogram, in audiometric testing, provides a static reference point for future audiometric tests for a specific individual and lets a trained medical professional document any changes in hearing capabilities over time. It is used to monitor whether or not an employee's hearing level is decreasing or being maintained, so that any hearing loss can be detected early.

A baseline audiogram that shows a persistent shift for only one ear may be revised for only that ear. The baseline may not be revised for the other unaffected ear. This procedure is required because it provides a clear indication of how each ear is affected by noise.

The baseline audiogram is the reference against which future audiograms are compared in order to determine the extent to which an employee's hearing is deteriorating. If it is not conducted properly, it will not reflect the employee's true threshold, and any changes between baseline and future tests may be masked.

The baseline is the first audiogram obtained upon entry into the hearing conservation program. This test may be a pre-placement audiogram. In the event that there are two audiograms performed within the first twelve months, the professional supervisor will determine which audiogram will serve as the reference baseline for all subsequent review.

Using OSHA criteria, a reviewer of audiograms will identify an STS (or "Standard Threshold Shift") if the hearing threshold has changed (relative to the baseline audiogram) an average of 10dB or more at 2000, 3000, or 4000 Hz in either ear. Age corrections (listed as an appendix in the OSHA standard) may be used when determining STS, although they are not …
