Answer 1

Permissible noise level in India

In industrial areas, the permissible limit is 75 dB for daytime and 70 dB at night. In commercial areas, it is 65 dB and 55 dB, while in residential areas it is 55 dB and 45 dB during daytime and night respectively.

Exposure to prolonged or excessive noise has been shown to cause a range of health problems ranging from stress, poor concentration, productivity losses in the workplace, and communication difficulties and fatigue from lack of sleep, to more serious issues such as cardiovascular disease, cognitive impairment, tinnitus .

India is one of the noisiest countries in the world. Our cities generate a cacophony of high-intensity sounds, mainly due to the rapid but unscientific industrialisation and urbanisation processes.
