Noise
Noise is all around you, from televisions and radios to lawn mowers and washing machines. Normally, you hear these sounds at safe levels that don't affect hearing. But sounds that are too loud or loud sounds over a long time are harmful. They can damage sensitive structures of the inner ear and cause noise-induced hearing loss.
