Sound Absorption Coefficient in Natural Flax Fibers

, 2010
There are two methods of measuring the amounts of sound absorbed by various materials. One is the reverberation method, in which a specimen of the material to be tested is mounted on the walls of a reverberation chamber and the coefficient of absorption is deduced from the effect, which the presence of the specimen has on the rate of decay of sound in ...
