Millions of workers are subjected to countless sources of noise every day ranging from construction to manufacturing to utility jobs. Most of these mundane noises are heard at a safe level and do not affect hearing… but when workers are exposed to noise that is harmful, these seemingly unavoidable sounds on the job could be the cause of a worker to never hear again. That is because sounds simply are too loud or are loud for a long enough time to damage the sensitive structures in the inner ear. This can lead to noise-induced hearing loss — and many of these harmful noises can be found in the workplace.
