acoustics

Acoustics, a term originating in the Greek language, can be used in different ways. What adjective, refers to what is linked to hearing (the organ that allows hearing) or what is conducive to sound being generated or propagated.

For example: "When this machine overheats, it emits an acoustic signal to warn the operator", "I'm going to carry out an acoustic conditioning of the laundry room to turn it into a radio studio", "Due to the explosion, the young man suffered acoustic nerve damage".

Acoustics is also the branch of the physical that is responsible for the generation, propagation, storage and reception of a sound, an ultrasound or an infrasound. In this way, it works with mechanical waves whose propagation takes place through a gaseous, liquid or solid matter.

There is talk of musical acoustics, in this sense, to name the specialization focused on the physical issues of the music, whether in generation, broadcast or audition. Objective and subjective issues come into play in these studies.

The acoustic music, on the other hand, is the one generated without the use of electronics or electricity. A acoustic guitar, in this way, it uses its resonance box to amplify the sounds, unlike the electric guitar (which transforms the vibrations of the strings into different electrical signals).

What noun, the notion of acoustics refers to features of a space in terms of the possibilities it offers to receive sounds. A place with good acoustics is one that favors the faithful reception of a sound: "This theater has excellent acoustics", "I don't like the concerts that take place in this stadium: the acoustics are not good".

On the other hand, we talk about noise pollution to refer to one of the most serious problems of modern societies, since it is a phenomenon that affects our Health without us being aware of them, simply by passing through the noise sources or, worse still, by staying in them for long periods of time.

It is important to note that noise pollution is an almost inevitable consequence of modern life, and therefore represents a very big challenge for governments. Let's see below the most common sources of noise pollution:

* industrial activities: at this point we find the effect that generates the activity of factories and mines, among other establishments. If the people in charge of your organization do not take adequate measures to prevent the leakage of large levels of noise to the outside, then they become major threats to the health of citizens;

* transport: This is perhaps the most common source of noise pollution, or the one that the public usually perceives as the main cause of this problem. It occurs especially in large cities, where the volume of cars that travel the streets is overwhelming;

* construction: especially in cities with a healthy and growing economy, construction takes place throughout the year, either to expand or to maintain buildings, and this generates a series of various disorders, among which pollution stands out acoustics. In fact, the workers are obliged to use the so-called headphones protection, to protect your ears from the noise that your tasks inevitably produce;

* social habits: Although this takes place mainly in the central areas of cities, nighttime activities that include playing music at a large intensityIn addition to shouting and other noises until late at night, they can deprive neighbors of rest, which has repercussions in various health disorders.
