why is wood and glass are often used to soundproof rooms
Answers
Answer:
Glass is very acoustically reflective because it is flat and rigid. But the problem with glass is that it can bend depending on the thickness and it is usually made quite thin. Wood conducts sound because it is easy to move but it also absorbs like a sponge blocking some sound.
Answer:
Because wood is rigid and prone to vibration, lots of sound will transmit through it, and not much will be absorbed. ... Materials like wood, glass and paper have low absorption coefficients, while studio foam and soundproof insulation have coefficients closer to 1.
wood is good at sound absorption because it's porous, with plenty of air spaces to trap sound.manufactured wood types such as Medium Density Fiberboard (MDF) are engineered with high density and mass while retaining the natural porosity of wood.
Glass is an excellent material for soundproofing, or sound insulation as it is more properly called. The reasons for this are firstly that it is dense, meaning that you get a lot of mass in a fairly small thickness Secondly that it is non-porous - it doesn't have holes where sound can leak through.
