Acoustic music is generated without the use of electricity or electronics.
Acoustics is a term with origins in the Greek language that 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 to sound being generated or propagated.
For example: “When this machine overheats, it emits an acoustic signal to warn the operator” , “I am going to carry out acoustic conditioning of the laundry room to turn it into a radio studio” , “Due to the explosion, the young man suffered damage to the acoustic nerve .
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” .
A branch of physics
Acoustics is also the branch of physics that is responsible for the generation, propagation, storage and reception of sound, ultrasound or infrasound . In this way, it works with mechanical waves whose propagation develops through a gaseous, liquid or solid matter.
We speak of musical acoustics , in this sense, to name the specialization focused on the physical issues of music , whether in generation, emission or listening . Objective and subjective issues come into play in these studies.
Acoustic music , on the other hand, is music generated without the use of electronics or electricity . An acoustic guitar , in this way, uses its soundboard to amplify sounds , unlike the electric guitar (which transforms the vibrations of the strings into different electrical signals).
Noise pollution is caused by excess noise in an area or environment.
Noise pollution
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 it, simply by passing through 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 that is why it represents a very big challenge for governments. Let's look at the most common sources of noise pollution below:
- 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 high levels of noise from leaking outside, then they become major threats to the health of citizens.
- Means of transportation : This is perhaps the most common source of noise pollution, or what the public usually perceives as the main cause of this problem. It occurs especially in large cities , where the volume of cars traveling the streets is overwhelming.
- Construction works : especially in cities with a healthy and growing economy, construction takes place throughout the year, whether to expand or maintain buildings, and this generates a series of various disorders, among which noise pollution stands out. In fact, workers are required 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 central areas of cities, nighttime activities that include playing music at high intensity , as well as shouting and other noises until late at night, can deprive neighbors of rest , which has an impact on various health disorders.
