Being the social animals that they are, humans need to be comfortable in all situations. The fact is that people can’t enjoy their lives fully, because the resources of the planet are depleting, as a consequence of the war between the environment and men. Noise pollution is a huge problem these days, as technology evolved to a point where a city might have millions of cars in it.
Noise pollution happens when sounds that are irritating and distracting can be heard clearly and end up causing harm to humans or disturbing natural processes. They can affect both human and wild life in a negative way. Noise is actually an unwanted sound by itself, no matter what its source is. For example, the best kind of music will sound divine for someone, but will annoy a person that wants to sleep and can’t because of it. Depending on what the circumstances are, any type of sound can be considered noise.
Pollution by noise affects all kinds of life, from birds, to animals and humans. Noise can cause a number of problems for humans, like digestive or cardiovascular problems, blood pressure, hypertension, annoyance, headaches, insomnia or hearing loss.
Studies say that the level of noise that a human can usually tolerate is between 40 and 50 dB, and if you are exposed to more than 90 dB of noise, you are in danger of suffering from hearing loss. That is why noise pollution is regulated through laws and there are limits that can’t be surpassed by anyone.
There are areas where noise is less tolerated than in others, and these zones are around educational institutions, religious places, hospitals or other areas indicated by the local law. If the noise pollution laws are not respected, action can be taken against the offenders, from giving fines to worse punishments.
