noise pollution level

What is it about?

Noise pollution level refers to the degree and intensity of noise in the environment. It is usually measured in decibels (dB), which is a logarithmic expression of sound intensity. The higher the level of noise pollution, the greater the noise and the more severe its impact on the environment and human health. The level of noise pollution is mainly affected by the following factors: Noise sources: Noise can come from transportation, industry, construction sites, machinery and equipment, music, etc. The pollution level generated by noise from different sources also varies. For example, the noise generated by mechanical equipment is usually higher than traffic noise. Distance: The noise intensity decreases with increasing distance.
