Question

Maximum permissible noise for industrial areas as per Noise Pollution Rules 2000 is
A. \[75dB\]
B. $65dB$
C. $55dB$
D. $45dB$

Answer 1

Hint: Noise pollution refers to unbearable sound production that harms the health of living beings. The road traffic, industrial working machinery, commercial units working are forms of noise pollution. The degree or the intensity of sound is measured in decibel. The permissible noise level refers to the allowed degree of sound that a unit can produce. The maximum permissible noise of industrial areas is higher than any other noise-producing units.

Complete answer: Noise pollution along with air and water pollution is also considered hazardous to the physiological health of living beings. Noise pollution refers to exceeding the healthier levels of sound that can harm people. Sound beyond a particular intensity is considered unwanted. Sound is measured using the decibel units. Decibel denotes the degree of intensity of sound. Every working unit or sound-producing unit has its set sound limit that controls the intensity of sound production.
-The Government of India under the Ministry of Environment and Forest control published noise pollution rules in 2000. Various units like industrial activity, construction activity, generator sets, public address systems, music systems, loudspeakers, etc. These were considered to have lethal or hazardous effects on human health and well being of people. The rules set the permissible limits of noise pollution in these areas.
-The maximum permissible noise set for various units is as follows-
Permissible limits of noise pollution in silence zones are prescribed as $50dB$ during the day and $40dB$ during the night. For the residential area, it is $55dB$ during the day and $45dB$ during the night. For commercial areas, the limit is set around $65dB$ during the day and $55dB$ at night. The maximum permissible noise set for Industrial areas is $75dB$ and $70dB$ during day and night respectively.
Therefore, the right answer is option A.

Note: Noise pollution rules also set some consequences for people who violate these rules. Certain penalties were set for violating people. The penalty was considered for people who will play any music using sound amplifiers, who will blow horn in inappropriate situations, etc. To avoid noise pollution certain measures can be taken. This involves avoidance of unnecessary use of horns, the loudspeaker in marriages, unwanted noise of drums, etc.
