Noise is also characterized by pitch (frequency) and high frequency noises seem louder and more irritating the ear than low frequency of the same power. The effects of noise are usually high frequency sounds to which people are more sensitive, is scored on a scale of decibels A (dBA), in units of dBA. The effect of noise becomes threat at approximately 75 dBA, painful at 120 dB and death at 180 dBA.

Some people noise annoys, others less. The noise is not able to directly kill a person, but at the same time he is the cause of many nervous system disorders and heart disease. Constant noise over 80 dB leads to gastritis and stomach ulcers. Even if a person thinks that he is used to noise and have not noticed it, in fact, human health continues to deteriorate.

Mankind has long recognized the harm that can cause noise. Two thousand years ago, Julius Caesar banned carts to ride through the streets of Ancient Rome at night. The noise control is today – invented the noiseless engines for aircraft and automobiles, trains run on rails fainter, and appliances will soon not be heard. It is in our interest as much as possible to take care of silence.
