Audiometry testing is mandatory for all employees regularly working above an upper exposure action value (Noise hazard area). You may also wish to consider testing employees who have additional risk factors, such as existing hearing loss and for those working in areas/roles where good hearing is considered essential to an individual’s or others health and safety. For new employees, testing should be carried out initially as soon as they accept an offer of employment in order to determine if the individual has any pre-existing hearing issues. Early knowledge of a pre-existing problem can be vital enabling prompt remedial action and minimise future liability.
If you are not sure if your employees are exposed to a noise hazard, Phoenix Occupational Health can recommend an occupational hygienist to conduct a noise survey.
