Noise pollution

This is a type of contamination characteristic of urban areas or societies, which, although not given much consideration, has a great impact on the mental health of the inhabitants of a region, which will affect the fulfillment of activities in the short or medium term. routine that an individual possesses, noise pollution is a product of the different activities that are carried out in a region, specifically in large cities.

It is characterized by being a set of annoying and strident sounds, which can cause harmful psychological effects for the inhabitants, if they are exposed to it frequently enough; The main reason why it is very difficult to eradicate this type of pollution is its origin, since it is produced only by the performance of daily activities by the individuals who inhabit said sector, such as noise from transport, noise emitted by machinery implemented for the construction of public roads or buildings, the noise generated by the work of industrial companies and other purposes. Long-term damage can be physiological, such as partial or total hearing loss, or psychological, such as irritability, stress, phobias, etc.

The differences that noise pollution can have with respect to other types of pollutants can be: its origin is cheap, and the emission of strident sounds is achieved by consuming little energy, the measurement of sound levels is difficult and its quantification to a plus is, however, the world health organization declared that 50 decibalos is the noise level considered “normal” since it does not cause any harm to individuals, another difference is that there is no evidence of residues, thus nor does it produce cumulative effects in the environment, but in man.

Sonic pollution is only identified by a single sense (hearing), thus being able to be considered as a subjective effect of each person, which of course makes it difficult to identify said pollution, while other environmental pollution can be evidenced with all the senses such as for example: contaminated water is identified by its foul odor, by the observed coloration (usually dark) and by the perceived taste.
