How do you know which soundproofing material is best for the job? There are some guidelines to selecting the best soundproofing material for any specific area of a home or office. The goal is to get the best noise reduction for the least amount of money.
Soundproof Windows
Much of the noise that enters a home, building or even a specific room comes from the outside. By installing soundproof windows, you will get the greatest reduction in noise compared to any other type of home improvement, including that achieved by replacement windows or storm windows.
Soundproof windows work by adding a second layer of window inside your existing windows. The extra glass layer plus the pocket of air created by the second interior window provide the soundproofing. Glass deflects sound and the air helps it dissipate, so the two together are quite effective in diminishing noise levels.
Adding soundproof windows to a home can decrease perceived noise by 75%. In reality, the actual noise as measured in decibels on an instrument is reduced by 95%.
Soundproof Walls & Floors
To soundproof walls there are a couple of different types of insulation materials that reduce noise and control the heat or coolness of the room. Fiberglass insulation can be inserted between the studs between drywall layers. There are also materials that soundproof rooms with foams. To upgrade the insulation or soundproofing of a home, you can blow a foam type of insulation right into the wall without having to remove the entire piece of drywall.
Floor sound insulation is installed the same way as for walls. It can make the noise of people upstairs much quieter for the below them.
Acoustical Applications
Often soundproofing is used to improve acoustics. Acoustical engineering works to create materials that will absorb sound to that it is not reflected back, thereby making the room quieter and sound proof. Acoustics are quite important for home theatre systems or recording studios. Anyplace where real sound without reflection or reverberation is required is a good place to use acoustical material. Foam squares that pad a room’s walls are an effective acoustical and soundproofing material.
