Hearing Damage. 
Unwanted sound is called noise. It is measured in decibels (dB). 
High levels of noise can damage your hearing. People who work in noisy environments wear ear defenders to cut down noise levels.
Exposure to a high level of noise can cause temporary deafness, and repeated exposure over a period of time can cause permanent hearing loss.
