In reverberation chamber testing conducted two phases of testing which is testing empty room time and using coconut fiber specimens. Specimens of coconut fiber used in the test consists of two types of specimens of type A and B. Testing is done by referring to the reverberation room measurement method. Reverberation time of the test results generated on a empty room indicates that each space has a reverberation time characteristics of a given frequency. At the sound absorption coefficients obtained specimens A pretty good at absorbing sound at a medium frequency, where as specimen B is quite good at absorbing sound at high frequencies.
