Hearing Conservation

Royal Roads University provides and maintains a hearing conservation program designed to control noise where practical, safely manage staff exposure to noise and also provide regular audiometric testing of RRU staff who may be exposed to excessive noise. This program is supported with education and training.

Noise Control

All RRU work sites such as shops, sheds, vehicles and equipment will be regularly measured to determine noise levels. Noise exposure levels to staff will not exceed 85 dBa over an eight hour work-day nor exceed 135 dBa at peak sound levels.

Wherever it is not possible to engineer work sites or equipment to below acceptable noise levels, hearing protection will be supplied to all staff and must be worn.

Noise Hazard Areas

Areas where noise levels exceed the 85 dBa daily exposure limit or the 135 dBa peak sound exposure limit must be clearly posted, warning employees of these dangers. In these areas, hearing protection is mandatory.

Hearing Tests

All RRU staff that work in areas where there have been identified excessive noise levels will have audiometric hearing tests conducted on an annual basis.

This testing will be conducted by qualified hearing testing persons who will:

  • Compile accurate records
  • Advise the staff member of the results of the test
  • Counsel the staff member on the use and maintenance of hearing protection
  • Provide Human Resources with test results to retain confidentiality
  • Forward test results to WCB on prescribed form


This hearing conservation program will be audited annually by the Occupational Health and Safety Committee. The audit will review:

  • Need for further noise measurement
  • Further education and training of staff in hearing conservation
  • Adequacy of noise control measure
  • Type and use of hearing protection
  • Results of hearing testing or related claims experience
