Loud noises occur every day. Wincing at the annoyance of a dog bark, or covering your ears as you pass a construction sight is the standard way to guard against the harsh sounds. The pain threshold for humans is 120-130 Decibels. Any sound above 85 dB can cause hearing loss, and the loss is related both to the power of the sound as well as the length of exposure. Here are 10 sounds produced throughout history and how incredibly loud they are. Just remember, human speech is only registered at about 25-35 decibels.

A 400,000 Wat rock concert or a similar set of speakers mounted in a vehicle can reach ear-splitting decibel levels. Is it any reason most promoters recommend you wear ear protection to stave off the 135-145 decibel sound waves?
