NOISE POLLUTION PROBLEM AND SOLUTIONS

POLLUTION “Pollution means any contamination of air, soil, water and environment., Even loud noise and sound is also a part of pollution.”

NOISE “The word noise comes from the Latin word noxia meaning "injury" or "hurt".” Noise is an unwanted, unpleasant and annoying sound caused by vibration of the matter. Vibrations impinge on the ear drum of a human or animal and setup a nervous disturbance, which we call sound. When the effects of sound are undesirable that it may be termed as “Noise”.

Physically there is no distinction between sound and noise. Sound is a sensory perception and the complex pattern of sound waves is labeled as noise, music, speech etc. Noise has become a very important "stress factor" in the environment of man.

MEASUREMENT OF NOISE “A decibel is the standard for the measurement of noise” 20 db is whisper. 40 db the noise in a quiet office. 60 db is normal conversation. 80 db is the level at which sound becomes physically painful. And can be termed as noise.

LACK OF CONCENTRATION For better quality of work there should be concentration, Noise causes lack of concentration. In big cities, mostly all the offices are on main road. The noise of traffic or the loud speakers of different types of horns divert the attention of the people working in offices. Deficits in concentration can lead to accidents.
