Workplace Hearing Test (Audiometry)
How Is the Hearing Test Performed?
In the hearing test service, a fixed or portable screening audiometry device is used and tests are performed in a silent booth (Art.10/1). An automatic or manual audiometer may be used for the test. In practice, appropriate methods and sound levels capable of detecting even the lowest level of hearing loss in the worker are used.
Device and Calibration
Calibration of silent booths and audiometers is performed at regular intervals by authorized services (Art.10). Calibration is decisive for the reliability of measurement results and the accurate detection of low-level hearing loss.
| Element | Principle |
|---|---|
| Device | Fixed or portable screening audiometry device |
| Audiometer type | Automatic or manual |
| Environment | Silent booth |
| Calibration | At regular intervals by authorized services |
Who Performs the Test, Who Evaluates the Results?
The hearing test is performed by an audiologist or audiometrist (Art.10/3). Test results are evaluated by the workplace physician; upon request, reporting is done by an ear, nose and throat (ENT) specialist (Art.10/4).
Where Is It Performed?
The hearing test can be performed at a fixed center, or it can also be carried out directly at the workplace with a mobile occupational health vehicle. In both cases, the same principles apply with respect to the silent booth, calibration, and practitioner qualifications.
