751 Hearing Conservation Program Management

Audiometric Testing

There are two types of audiograms required in the hearing conservation program: baseline and annual audiograms. The employer must establish and maintain an audiometric testing program.

The important elements of the program include:

• baseline audiograms,
• annual audiograms,
• training, and
• follow-up procedures.

Employers must make audiometric testing available at no cost to all employees who are exposed to an action level of 85 dB or above, measured as an 8-hour TWA.

The audiometric testing program follow up should indicate whether the employer's hearing conservation program is preventing hearing loss.

A licensed or certified audiologist, otolaryngologist, or other physician must be responsible for the program. Both professionals and trained technicians may conduct audiometric testing. The professional in charge of the program does not have to be present when a qualified technician conducts tests. The professional's responsibilities include:

• overseeing the program and the work of the technicians;
• reviewing problem audiograms; and
• determining whether a referral is necessary.

The employee needs a referral for further testing when test results are questionable or when related medical problems are suspected. If additional testing is necessary, the employer must refer the employee for a clinical audiological evaluation.
