Noise pollution is increasing across the world due to the increase in human activities in urban areas. The main causes of noise pollution are man-made and environmental noise.
As per some studies, 60 dBA is considered a safe noise level for humans but in developing countries, the noise pollution could go as high as 90 dBA and up to 110 dBA.
Some ways in which this can be done include, technical planning, behavioral studies, and developing educational strategies that involve raising awareness of the citizens.
