The loudness of sounds - decibel levels

The chart shows some of the approximate sound levels. You can see that really loud sound scan actually be very dangerous. Loud music played through an earpiece may be a particular problem. The distance from the sound source to your rears is very important. The further away you are the better.

Think about places which are really quiet. Is there always music being played in public places such as shopping precincts, cafes, clubs, discos and restaurants?

Is this a good thing?
