wood, the principal strengthening and nutrient-conducting tissue of trees and other is insulating to heat and electricity, and has desirable acoustic properties. from metals, plastics, cement, and other materials, wood maintains a place in
acoustic properties wood can produce sound by direct striking and can amplify or absorb sound waves originating from other bodies. for these reasons, it is a unique material for musical instruments and other acoustic applications. the pitch of sound produced depends on the frequency of vibration,

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. wood conducts sound better in the
acoustic properties of building materials in many cases help from an acoustic designer is required after the building construction is complete and is occupied to high level of sound. the discomfort faced by the occupant residing or using it, have to go for redesigning the building for noise insulation.

the purpose of protecting wood is to preserve the good properties of wood and wood products and, at the same time, to prevent damage by decay, fungus, pests, etc. usually, wood can keep untreated for long periods if the material receives adequate structural protection. a prerequisite for the long-term durability of wood is, among other things, to keep its moisture content
in short, the answer is you can use wood for this purpose, but because it lacks acoustical properties, its not a really good choice in and of itself. first of all, wood is light, so its not a perfect choice if you want to block sound. also, it is usually too smooth and has too dense of a surface to absorb sound well.
acoustical properties. wood has some unique properties that allow it to contribute to noise reduction in buildings and in industrial applications. industrial noise control has gained considerable importance due to the requirements established by osha. audible sound is a propagation of energy which is commonly measured in terms of decibels db .
