Noise Exposure Monitoring, Control and Abatement

Whenever noise exposures equal or exceed an 8-hour TWA of 85 decibels, or a daily noise dose of 50% of the PEL of 90 dBA, OSHA's Noise Standard requires employers to develop and maintain an effective hearing conservation program.

BDN can monitor potentially affected employees using noise dosimeters and sound level meters to determine 8-hour TWA noise exposures. We can also measure peak impact, impulse noise and octave band analysis.

Monitoring results are analyzed to determine the proper level of hearing protection that may be warranted. Noise abatement management is also available.
