Acoustic properties for composite materials based on alfa and .

The maximum value of the sound absorption coefficient corresponding to spruce and beech wood fibers based composites are 0.98 at 2048–2288 Hz and 0.98 at frequency range respectively. The size of the air gaps thickness and of the additional woven flax shell layer has some significant effects especially for the low frequencies.
