Importance of Acoustics

Acoustic of sound is manipulation or study sound through Frequency, or its inverse, wavelength, Amplitude, sound pressure or Intensity, Speed of sound. Effecting the reflection, refraction, absorption, diffusion and interference of sound. All of these factors combined defines Acoustics of sound. When we are not able to hear sound from outside the space and do not let any sound skip out of the space this can be defined as "isolation" of sounds.

Anyhow, when we apply acoustics to an enclosed space the major concern behind that is to get rid of the echo's and reverberations. Now, to get rid of these echo's we need some kind of absorption despite isolation because then the echo's will not be able to sneak out rather will keep bouncing inside the space.

Therefore, acoustics provide nanotechnology of absorption in the room to reduce the echo wave-length. Hence, acoustic panelling's are made porous so that it can allow sound to pass through but by splitting it in multiple smaller waves.

This objective of porosity proves that providing acoustics does isolate the sound, but absorb it, sometimes reflect and diffuse it.
In the bigger halls and empty spaces, sound tends to bounce rapidly
