What is the Regulatory Standard for Hearing Testing in the Trades?

As the need for audiometric testing steadily grows, many businesses are looking to find more information about this interesting topic. One of the questions on the top of their minds is, “what is the regulatory standard for hearing testing in the trades?” As long-time proponents of hearing health and testing, we couldn’t be happier to provide information on this, which we do below.

Provincial Legislation


Within Alberta, all safety legislation falls under the purview of Occupational Health and Safety. Three documents offer information about this legislation and audiometric testing, namely the OHS Act, Regulation and Code. For specific information about noise exposure, refer to Part 16 of the Code. 

British Columbia

In British Columbia, five documents are essential to the understanding of audiometric testing and safety at the workplace. These documents are: 

For specific information about noise exposure, refer to the OHS Guidelines, Division 1 -Noise Exposure.


In Saskatchewan, health and safety standards operate under The Workers’ Compensation Act, 2013, together with The Workers’ Compensation General Regulations, 1985 and The Workers’ Compensation Miscellaneous Regulations. For links to downloadable versions of these resources, consult this page on their website. Information specifically related to audiometric testing can be found in POL 11/ 2012 of the policy and procedure manual.
