Noise Level Measurement

You are here: Home Noise Industry Noise Level Measurement

Essentials of a Hearing Conservation program:

1. Training of employers and workers
2. Noise exposure measurements
3. Regular audiometric hearing screening (in cases where hearing protection is required)
4. Follow up diagnostic audiological examinations for those workers who failed* the audiometric screening

Noise Exposure Standard in Victoria: 85dBA noise level for 8 hours and peak noise level 140dBC. For every 3dB above this, the duration of exposure is halved, eg. If the noise level is 88dBA, the maximum duration a worker may work is 4 hours. The appropriate attenuation rating of a hearing protector will result in keeping the exposure below the standard.
