Acoustic Coefficient is the measurement unit for rating an acoustical material. The Acoustic Coefficient is measured at a specific frequency. The values can go from 0 which means that the material is reflective to 1 which means that is totally absorptive.

Absorber
Absorber is a block of material and sometimes a device which reduce the level of sound waves. Also the absorber can block the propagation of sound by reducing to zero. The converted sound energy is transforming to heat. What materials can be absorbers? Every material is an absorber even if the coefficient of absorption is […]
Haas Effect
Haas effect is a bin-aural psycho acoustic effect regarding the sound source localization. It is known as the “precedence effect” or the “law of the first wavefront” and it was define and described by Helmut Haas in his Ph.D. Thesis in 1949. Shortly put, our hearing mechanism determine the position of a sound source based […]
Sound
The term “sound” refers to the mechanical waves that is an oscillation of pressure. The mechanical waves or the sequence of mechanical waves have the capability of propagation through all forms of matter: gas, liquid, solid, and plasma.
