Hearing damage is a real and unfortunate effect of long-term exposure to loud noise. Noise is a hazard of industrial workers and workers of any occupation who are repeatedly exposed to loud noises. Noise induced hearing loss is fully preventable when the right precautions are taken from the start. Regular hearing tests to evaluate any early signs of hearing loss, as well as everyday preventative measures such as the use of ear plugs go a long way toward preventing permanent hearing loss.
