acoustical properties of woods. musical instrument makers and physicists have studied the acoustical properties of wood for many years. they have determined that different species of woods sound out differently when struck or vibrated. for this reason, wood selection is critical for the best sound out of an instrument.

wood density is the oldest and most widely used criterion for the evaluation of wood. according to bamber and burley 1983 it has a considerable influence on strength, machinability, conversion, acoustic properties, wearability, paper yield and properties. and probably many others.
acoustic properties of wood. sibeliustalo23auerniitty web.jpg. wood is a light material, so as such its sound insulation performance is not particularly good. neither does a thick, dense-surfaced and smooth wooden structure dampen sound particularly well, so wood alone is not a good absorption material.
