| Noise Stop Soundproofing & Noise Explained |
Noise
pollution is not easily defined. Part of the difficulty lies in
the fact that in some ways it is different from other forms of pollution.
Noise
is transient; once the pollution stops, the environment is free
of it. This is not the case for chemicals, sewage, and other pollutants
introduced into the air, soil, or water.
The
definition of noise itself is highly subjective. To some people
the roar of an engine is satisfying or thrilling; to others it is
an annoyance. Loud music may be enjoyable or a torment, depending
on the listener and the circumstances. Broadly speaking, any form
of unwelcome sound is noise pollution, whether it is the roar of
a jet plane overhead or the sound of a barking dog a block away.
One
measure of pollution is the danger it poses to health. Noise causes
stress, and stress is a leading cause of illness. Therefore any
form of noise can be considered pollution if it causes annoyance,
sleeplessness, fright, or any other stress reaction. Should you

What
is dB ?
Decibel. A unit for measuring the relative strength of a signal.
Usually expressed as the logarithmic ratio of the strength of
a transmitted signal to the strength of the original signal.
A decibel is one tenth of a "bel".
How
does Sound Travel ?
Sound travels in different ways depending on the medium. The medium
is the material the sound is using to travel. Air is the most
common. When sound travels through the air it normally originates
from somewhere in space, like a speaker or a person's mouth, and
then the waves travel in spherical ripples, this is similar to
water waves: those travel in circular ripples because the surface
of water is flat.
