Noise pollution

We have argued that urban populations have been transformed into cities of chaos as a natural fact. However, excessive noise, high decibels that alter the acceptable environmental conditions in a given area are called sonic pollution, says Gustavo Copelmayer.

It is known that noise does not accumulate, nor does it move or remain over time as other pollutants do. It is simply an immediate contamination that leaves profound consequences on the quality of life of all people and all environments if it is not properly controlled. The terminology of noise or auditory pollution, indicates Gustavo Copelmayer, is described as that which is given by thunderous and annoying sounds, which are generally reflected by human activities, such as traffic in the streets, industries, leisure venues and parties, the sound of airplanes, boats and many more, causing different negative results for the natural environment.

Likewise, unhealthy effects are given off for the auditory, physical and neurological functioning of human beings and worsen with the passage of time without there being any solution or reduction of the medium where it is found. On the other hand, adds Gustavo Copelmayer, the definition is directly related, implying noise as the only and total pollutant that gives rise to harmful consequences for groups of people as a whole, generating psychological, psychopathological, behavioral and memory effects.

In noises of more than 60 decibels (dB), humans respond by increased blood pressure, causing intense headaches and with it, dilation of the pupils. It induces rapid blinking as well as altering the rate of respiration and pulse. In noises of more than 85 dB, the effects, Gustavo Copelmayer indicates, are the decrease in gastric secretion, in addition to the elevation of cholesterol and triglycerides, thus being associated with the risks of cardiovascular diseases. Glycemia is even increased having a predisposition to diabetes if it is established in this environment with maximum frequency.

In conclusion, sonic or acoustic pollution can produce or advance neurosis in those with the affected gene, episodes of insomnia, as well as intervene in the appearance of aggressive and irritable attitudes. In addition, Gustavo Copelmayer concludes, nature and the sensitive ecological balance are also affected.
