What is Acoustics:
The acoustics is the branch of physics that studies the generation, propagation and properties of sound. The word, as such, comes from the Greek ἀκουστικός (akoustikós), which in turn derives from ἀκούειν (akoúein), which means ‘to hear’.
In this sense, acoustics deals with the production, control, transmission and reception of sound waves that propagate through matter, whether they are sound, infrasound or ultrasound.
Likewise, acoustics also refers to the discipline that studies the storage and reproduction of sounds.
On the other hand, acoustics can also refer to the characteristic of an enclosure depending on the quality of the reception of sounds within it: “This room has impeccable acoustics for concerts.”
musical acoustics
As musical acoustics is called that which is responsible for the study of the production and transmission of the sound generated from musical instruments. In this sense, musical acoustics specializes in the investigation and description of the way in which sounds are used to produce music. Likewise, it is a discipline that seeks to improve the sounds coming from musical instruments and the voice.
Architectural acoustics
The architectural acoustics is the one that is responsible for the study of phenomena related to the propagation of sound in premises and buildings. In this sense, it is a discipline that studies sound control in both open and closed spaces, either to obtain better acoustics or to achieve adequate sound insulation.
