Continuous exposure to loud noises can lead to hearing loss over time, as the intense sound waves wear away the delicate hair cells known as cilia in your inner ear. Cilia are responsible for transforming sound waves into electrical signals that your brain can interpret as sounds - meaning your ability to hear is negatively impacted when your cilia are damaged. This kind of hearing loss can be permanent, so it is important to take the risks posed by noise exposure seriously. There are a lot of ways someone could be exposed to unsafe levels of noise, but a common place where people encounter this issue is in the workplace. How to Know if Your Work Puts You at Risk of Hearing Loss – And What to Do About It Unsafe Workplace Noise Levels The daily noise level exposure limit for an eight-hour workday is 85dB. In Canada, workplaces where employees may be exposed to noise levels that exceed that are required to provide hearing protection equipment and regular audiometric testing to their workers. Construction jobsites or workplaces with a lot of machinery are a few examples of places where the noise levels could prove to be hazardous to your hearing health. If you must often shout to be heard during a shift or are experiencing ringing in your ears at the end of a workday, the noise level at your workplace should be investigated so that appropriate measures can be taken to safeguard workers’ hearing health. Early Signs of Hearing Loss Damage to hearing from long-term exposure to dangerous levels of noise might not be immediately apparent to the sufferer. It can take time for noise-induced hearing loss to develop to a point that it is obvious, and the person affected by it likely won’t experience any pain. As such, it’s important to pay attention to smaller signs of hearing loss so that problems can be caught early. If you experience ringing or buzzing in your ears, you find yourself having to raise the volume higher than normal on the TV, find that speech sounds muffled or have difficulty hearing certain types of sounds (e.g. high-pitched sounds), you should book yourself in for a hearing exam. Not all potential warning signs are related to hearing. Some people might also experience feelings of dizziness, fatigue or pressure in their ears, so be sure to pay attention to any signs that something isn’t right with your ears. How to Minimize Your Risks of Noise-Induced Hearing Loss If you’re finding the level of noise at your workplace aggravating or feel like it could be hazardous to your hearing, it is important to take steps to protect yourself and your colleagues. Bring the issue to the attention of your supervisor or Health and Safety Officer so they can perform an exposure assessment and implement a noise management program. These programs should include regular audiometric testing and noise control measures, such as the use of earmuffs and ear plugs or finding ways to reduce the noise levels (e.g. purchasing quieter equipment or using barriers to muffle the noise). You can also take steps to distance yourself from noise sources at your workplace and take regular breaks from noisy areas. If you’d like custom noise protection, you can also have earmolds made that will match the contours of your ear and offer the best possible protection.
