Acoustics is defined as a Science of sound, its production, and transmission, biological and psychological effects. Those qualities of a room that, together, determine its character with respect to auditory effects.”
A scientist who works in the field of acoustics / Noise Control called an acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries.
In Acoustics, first we look the pressure levels and frequencies , sound wave and wave interaction of sound wave with the environment. This wave interaction can be described as diffraction, interference or a reflection or a mix of the three.
The Acoustics plays very important role in a covered environment to control sound reflection for sound purity the RT time will be 0.65 to 1.5 depending upon type of building and use of building.
Acoustic tiles can be control reverberation time , the NRC of acoustic tiles may be 0.50 to 1.0 depending upon the acoustic design , these tiles can be fix with ceiling OR wall also available in different colors , shape and thickness.
