Audiometric testing is required in workplaces with high levels of noise. Audiograms is the measure of hearing sensitivity over a series of frequencies (0.5KHz to 8KHz range). The audiogram includes examination of the outer and inner ear in order to identify abnormalities which could impede the ability to hearing pure tone sounds. An audiometric test is required for every two years in workplaces featuring high levels of noise according to Occupational Health & Safety regulations. We perform our tests with most updated, automated and advanced instrument in Fort McMurray.
