Hearing Conservation Program


Hearing Conservation Program

To prevent occupational noise-induced hearing loss, California Occupational Safety & Health Association (Cal/OSHA) requires California employers to implement a comprehensive hearing conservation program when noise exceeds 85 dBA over an 8-hour shift.

This program must include noise assessments, exposure controls, audiometric testing, proper hearing protection, employee training, and associated recordkeeping.

Developing a compliant program can be challenging. CDMS offers turnkey hearing conservation services. We perform noise monitoring, recommend controls, establish audiometric testing, select optimal hearing protection, provide training, and complete all required recordkeeping.

CDMS implements effective hearing conservation programs companies can roll out to protect employees from noise hazards and comply with California Occupational Safety & Health Association (Cal/OSHA).

When is a hearing conservation program required?
For employee noise exposures over 85 dBA as an 8-hour time-weighted average (TWA).

What are the key elements of the program?
Noise monitoring, hearing protection, audiometry, training, controls.

Who must oversee and manage the program?
The employer should designate a program administrator.

How frequently must noise monitoring be repeated?
Annually is recommended to identify any changes.

What training records need to be maintained?
Trainer, trainee names, dates, topics covered.

What audiometric testing records are needed?
Annual audiograms and any threshold shifts.

What level of hearing protection is needed?
To reduce exposures below 85 dBA and 50% attenuation rating.

How often should employees get audiometric testing?
Within 6 months of hire, then annually at minimum.

What are proper insertion techniques for protectors?
Roll foam plugs, proper insertion of muffs over ears.

Should the program discuss medical monitoring?
Yes, details on audiology exams and threshold shifts.

What engineering controls should be used?
Enclosing noise sources, installing noise dampening materials.

What administrative controls can reduce exposures?
Limiting duration in noise through rotation.

How long must records be retained?
Duration of employment plus 30 years.

What are signs of hearing damage employees should know?
Difficulty hearing conversations, ringing in ears.

Should the program review emergence response?
Yes, incident reporting and investigation.

How often should program reviews occur?
Annually at minimum to evaluate effectiveness.

What agencies oversee hearing conservation?
Federal Occupational Safety & Health Association (OSHA) and state plans like California Occupational Safety & Health Association (Cal/OSHA).

Should the program discuss noise controls for tools?
Yes, selection of low-noise power tools.

How frequently should training be conducted?
Annually at a minimum.

Can hearing protection ever be discontinued?
No, must always be used in hazardous noise areas.
