Audio Testing
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 every two years in workplaces featuring high levels of noise according to Occupational Health & Safety regulations.
Audiometric Testing & Safety
What is Audiometric Testing?
Audiometric testing is a non-invasive hearing exam used to measure the quietest sounds you can hear at various frequencies and volumes. By establishing a hearing baseline, we can monitor your ear health over time. The trends in your hearing results confirm that your workplace safety measures—such as ear protection—are effectively protecting your hearing.
Workplace Hearing Loss
Occupational hearing loss typically occurs through prolonged exposure to loud tools, heavy machinery, or engines. Over time, these sounds can wear down the sensitive hair cells of the inner ear. While a single extremely loud sound can also cause harm, most hearing loss is gradual and preventable with regular testing and proper PPE.
Hearing Fit Testing
Hearing fit testing measures the actual noise reduction a worker achieves with their specific hearing protection. This process ensures that earplugs or earmuffs are fitted correctly to provide the necessary attenuation. This is is done by using a a small probe microphone that sits just inside the ear canal. This microphone measures the actual sound level reaching the ear while the worker wears their hearing protection, so we can confirm the device is providing the right amount of noise reduction. These tests follow Occupational Health and Safety (OHS) standards to help protect workers from permanent hearing damage.
