Enterprise HealthAudiogramAudiometry
A hearing test that measures auditory thresholds, used to baseline and monitor workers in hearing conservation programs.
Key facts
- Measures hearing thresholds across frequencies.
- Baseline vs. annual audiograms detect standard threshold shifts.
- Career-long histories must be retained and trended.
What it means
An audiogram measures the quietest sounds a worker can hear across frequencies. In a hearing conservation program a baseline audiogram is compared with annual tests to detect a standard threshold shift — an early sign of noise-induced hearing loss that may be OSHA-recordable. Career-long audiometric histories must be retained and trended.
Frequently asked
What is an audiogram used for at work?
To baseline and monitor hearing in a hearing conservation program. Annual tests are compared to the baseline to catch a standard threshold shift — an early, possibly recordable sign of noise-induced hearing loss.
How long must audiometric records be kept?
For the duration of employment under OSHA's noise rules, because detecting threshold shifts depends on comparing tests over a worker's whole career. Trended histories are essential.
