baseline audiogram

baseline audiogram

A reference audiogram against which future audiograms are compared.

For workers occupationally exposed to loud sounds, a baseline audiogram must be provided within 6 months of an employee's first exposure at or above an 8-hour TWA of 85 dBA.

New employees should have a baseline audiogram within six months of starting their high noise job unless a mobile test van is used, in which case the audiogram may be conducted within one year of starting in the job.

When treatment success was reviewed based on the baseline audiogram types of patients, mean hearing gain was identified to significantly differ among the groups (p=0.018).

Neither patient had had a previous audiogram available to confirm an objective change in hearing thresholds, but having a baseline audiogram on hand for comparison is rather rare.

The first step in the prevention process is to obtain a baseline audiogram. The baseline audiogram serves as the reference point for all subsequent hearing tests and allows for changes in hearing sensitivity at a given frequency to be documented.
Hearing preservation in musicians
The Department of Defense uses the Occupational Safety and Health Administration's definition of an STS8: a change in hearing threshold relative to the baseline audiogram of an average of 10 dB or more at 2000 Hz, 3000 Hz, and 4000 Hz in either ear.

The first is that the employee experiences a standard threshold shift of at least 10 decibels in one or both ears, compared with the most current baseline audiogram (6) averaged at 2,000, 3,000, and 4,000 hertz.
Can you hear me now? Occupational hearing loss, 2004-2010: from 2004 to 2010, the manufacturing and utilities sectors had the highest rates of occupational hearing loss of all sectors listed at the two-digit level in the North American Industry Classification System (NAICS); primary metal manufacturing had the highest rate at the three-digit level
Ototoxic threshold shift from the initial baseline audiogram was defined as: (1) [greater than or equal to] 20 decibel (dB) decrease at any one test frequency, (2) [greater than or equal to]10 dB decrease at any 2 adjacent frequencies, or (3) loss of response at 3 consecutive frequencies where responses had previously been obtained.

Hearing protection is also mandatory for employees who nave been exposed to 85 dB(A) noise levels if they did not have a baseline audiogram, and for workers who experience standard threshold shifts--an average shift from baseline hearing levels of 10 dB or more at the audiometric frequencies of 2,000, 3,000, and 4,000 Hz.
