The World Health Organization (WHO) recommends that noise exposure levels should not exceed  [[1]] (35 dB/70 dB)over a 24-hour period.

The presence of excessive or unwanted sounds in the environment is called noise pollution. Noise level is measured in decibels (dB). The louder the noise, the higher the decibels.

The World Health Organization (WHO) recommends that noise exposure levels should not exceed 70 dB over a 24-hour period, and 85 dB over a 1-hour period to avoid hearing impairment.
