The Hearing Conservation Program

An effective hearing conservation program can prevent hearing loss, improve employee morale and a general feeling of well-being, increase quality of production, and reduce the incidence of stress-related disease.

A Hearing Conservation Program should allow employees to select the HPD they use.

The employer should administer a continuing, effective hearing conservation program whenever employee noise exposures are at or above an eight hour time-weighted average (TWA) sound level of 85 decibels or, equivalently, a dose of 50 percent.

Program Elements

As detailed in OSHA's 1910.95 rule, the elements of an effective hearing conservation program are:

  • Monitoring Program: When any employee's exposure may equal or exceed an 8-hour time-weighted average of 85 decibels, the employer must develop and implement a monitoring program.
  • Audiometric Testing Program: Establish and maintain an audiometric testing program by making audiometric testing available to all employees whose exposures equal or exceed the "action level" - 8-hour time-weighted average of 85 decibels.
  • Hearing Protection Devices (HPDs): Employers must make hearing protectors available to all employees exposed to an 8-hour time-weighted average of 85 decibels or greater at no cost to the employees.
  • Employee Training and Education: The employer must train each employee who is exposed to noise at or above an 8-hour time weighted average of 85 decibels. The employer must institute a training program and ensure employee participation in the program.
  • Recordkeeping: The employer shall maintain an accurate record of all employee exposure measurements.
