Acoustics Definition and Meaning

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

For example: “When this machine overheats, it emits an acoustic signal to warn the operator”, “I am going to perform acoustic conditioning of the laundry room to turn it into a radio studio”, “The young man suffered damage to the explosion due to the explosion acoustic nerve ”.

Acoustics is also the branch of physics that deals with the generation, propagation, storage, and reception of a sound, ultrasound, or infrasound. In this way, it works with mechanical waves whose propagation is developed through gaseous, liquid or solid matter.

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

The acoustic music, moreover, is that generated without the use of electronics or electricity. An acoustic guitar, in this way, uses its sound box to amplify sounds, unlike the electric guitar (which transforms the vibrations of the strings into different electrical signals).

As a noun, the notion of acoustics refers to the characteristics 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 in modern societies, since it is a phenomenon that affects our health without us being aware of them, simply by going through the sources of noise or, even worse, 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 generated by 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 exterior, then they become important threats to the health of citizens;

* means of 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 big cities, where the volume of cars that travel the streets is overwhelming;

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

* social habits: although this takes place mainly in the central areas of cities, night activities that include music playing at high intensity, as well as shouting and other noises until late at night, can deprive children of rest neighbors, which affects various health disorders.
