From Latin rugĭtus, a noise is a inarticulate sound that is unpleasant . For example: “The noise of the avenue is driving me crazy”, “My head hurts because of the noise produced by the factory machines”, “María José did not sleep all night because of the noise made by her neighbors”.

For the physical , the noise is a electrical disturbance that interferes with the transmission or processing of the signals. The thermal agitation of molecules The material that forms the conductors or the disorderly movement of electrons and other current carriers are some of the causes of noise.

In this way, we should talk that there is what is known as noise pollution. An east term that comes to define the excess of sounds and noises that exist in a city or locality and that supposes that the people who suffer from it see their quality of life overwhelmingly altered.

To such an extent the noise can affect the lives of those who suffer from it that these people may suffer certain diseases. Specifically, these pathologies can be of three types: psychic, physiological and sociological.

Stress, anxiety, insomnia, depression or loss of hearing ability are some of the most frequent diseases that people who have to face daily noise pollution problems in the environment where they have their homes can suffer.

There are certain people who are more susceptible than others when it comes to suffering that level of noise. Specifically, we should highlight children who can not only suffer from delayed reading learning but can also see how they experience serious problems when it comes to the development of their verbal communication.

In the same way, we must not forget that pregnant women are also very sensitive to the noises that can harm their fetus.

The communication theory and the semiology they claim that noise is a interference It affects the communicative process. In this sense, the noise can be the aphonia of the speaker, an unclear letter or the distortion of the image of a video, among other factors that make it difficult to understand the message.

Among the most frequent expressions that make use of the term noise is that of "a lot of noise and few nuts." With it, what we are trying to express is that there is a topic or an issue that, in principle, seems very important but then really shows that it is not.

In everyday language, we talk about noise to name the public impact of a fact or to the great appearance on things that really don't matter : "The words of the chancellor have produced a lot of noise in the neighboring country", "The coach's conference was pure noise as it did not clarify the reasons for his resignation", "The release of the album has generated noise in the rock environment", "I'm sick of the high-sounding statements that make so much noise: I want them to get to work and keep a low profile".
