In recent years

In recent years, authorities and society in general have begun to show growing concern about what could be considered a new polluting agent: noise. The phenomenon itself is not very new, but it’s characterization as a polluting agent is relatively recent. Noise is a level of sound that is not desired. The level of irritation produced is related to the time of exposure and the intensity. The harmful effects to the health of human beings caused by too much noise include problems with sleep, increased stress, loss of concentration in daily work, and even loss of hearing ability when the levels are very high or continue for long periods of time.
