In the beginning there was silence, and all was good. From silence came sound, not all of which was good nor welcomed. It was named noise.
Today more than ever we are bombarded with noise overload. Noise pollution has been known to cause aggression, hypertension, high stress levels, tinnitus, hearing loss, sleep disturbances, and other harmful health effects. Stress and hypertension are the leading causes to health problems, whereas tinnitus can lead to forgetfulness, severe depression and at times panic attacks. Is it no wonder that we have become what some consider as a violent and ailing world.
Below is a table of various noise levels. The dB scale is logarithmic so every 6 dB increase is double the sound level. So a street corner in a city at 80 dB compared to a quiet night in the country at 30 dB, is 128 time more noisy.
|Typical source of the noise||Typical noise level (dB)|
|Jet airplane taking off||130|
|Threshold of pain||120|
|Rock concert at stage||110|
|Side of a busy highway||90|
|Street corner in city||80|
|Side of a road with cars||70|
|Suburban area background||50|
|Suburban area at night||40|
|Rural area at night||30|
|TV recording studio||20|
|Audiometric test booth||10|
