Hint The noise level is shown on a logarithmic scale of decibels. Regular exposure to noise can occur in people who are irritable, nervous, and have difficulty making decisions. The World Health Organization (WHO) has recommended this limit.
Complete answer
The baseline noise levels in the society changes around 40 dB. International standards suggest the highest of 50 dB for day and 40 dB during night time in a residential area. Noise over 115 dB can be considered as highly avoidable. The World Health Organization (WHO) suggestions an industrial noise limit of 75 dB.
Additional information:
The CPCB has established the permitted noise levels in India for different areas. The noise pollution rules have defined the acceptable noise level in different areas, day and night. In industrial areas, the authorized limit is 75 dB during the day and 70 dB at night.
In commercial areas, it is 65 dB and 55 dB, while in the community’s areas it is 55 dB and 45 dB respectively during the day and at night.
So the correct answer is 75dB.
Note: It has been shown to interfere with the normal development of speech and hearing in children, resulting in delayed developmental stages that affect their overall growth.
The problem is significant in urban areas of India and therefore it is important that the authorities redouble their efforts to control and regulate noise pollution in order to protect millions of people.
The approach proposed by the CPCB will surely work as a deterrent. However, there are other aspects that CPCB needs to understand, especially those related to mass awareness.
