I've got came across this an exceptional publication for knowing a few features of wooden utilized in musical tool making. It confirms a few of the conclusions reached from functional adventure. I simply want there has been a bit extra that was once appropriate to device making.

If the acoustic insulation is good enough, the transmitted energy through the wall is very small. The acoustic capacity of a wall between two rooms is expressed by two factors: the noise reduction factor and the transmission loss factor. 1) The noise reduction coefficient is defined as the average of the sound absorption coefficients at 250, 500, 1,000, 2,000, and 4,000 Hz. 1. The highest sound absorption coefficient for all frequencies was observed for the floor with wool carpet and the smallest coefficients were measured on brick wall.
The positions of these last elements are essential in keeping the frequency spectrum of the reflected sound similar to that of the direct sound. − The materials used for the construction. Wooden-plated panels in front of an air cushion are used for the absorption of low frequencies. Wooden plates act as resonators, whereas the basic resonance frequency is related to the mass per square unit and to the stiffness of the air cushion behind. Wooden linings lead to a bright sound because of low-frequency absorption.
