Mineral wool is a material used in construction for the purposes of insulation and soundproofing. A sheet of 11 cm in thickness causes the original intensity to decrease to 63% of its original value.
You are trying to build a soundproof room that reduces sound coming in and out by 95%. That is, the intensity after crossing the walls is only 5% of the initial value.
What should be the thickness of the mineral wool used in the walls of your soundproof room?
im assuming I need to find the absorption constant from the 63% decrease and 11 cm thickness, and then use that value to find the thickness necessary for the soundproof room
