NOISE POLLUTION
INTRODUCTION:
Noise may not seem as harmful as the pollution of air or water but it is also a severe problem that affects human health and can contribute to a general deterioration of environmental daily.
NOISE:
The word “Noise” derived from the Latin word “Nausea” meaning seasickness, or any sensation of disgust, annoyance or discomfort. The most common definition of noise is “Unwanted Sound”. A sound might be unwanted because it is;
• Loud
• Unpleasant or annoying
• Intrusive or distracting
NOISE POLLUTION:
DEFINITION:
Noise is defined as “unwanted sound”. Sound, which pleases the listeners, is music and that which causes pain and annoyance is noise.
OR
“Noise pollution refers to sounds in the environment that are caused by humans and that threaten the health or welfare of human or animal inhabitants”.
Noise pollution is the type of environmental voices that disrupts the activity or balance of human or animal life. The word noise may be from the Latin word nauseas, which means disgust or discomfort. The source of most outdoor noise worldwide is mainly construction and transportation systems, including motor vehicle noise, aircraft noise, and rail noise. Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential area.
High noise levels can contribute to cardiovascular effects in humans, a rise in blood pressure, and an increase in stress and vasoconstriction, and an increased incidence of coronary artery disease. In animals, noise can increase the risk of death by affecting their ability of prey detection, interfere with reproduction and navigation, and contribute to permanent hearing loss.
MEASURING SOUND:
• Loudness/noise intensity is measured in decibels (db)
• Loudness of a sound is dependent upon proximity to source of sound
• No damage will be done to the ear if the sound level is below 80
