Sound-deadening materials play two roles; to help deaden sound and to eliminate vibration. These materials are beneficial in several applications including home theaters, auditoriums, movie theaters, teen bedrooms and hospitals. Vehicles benefit from the application of special sound-deadening materials which help keep down maintenance costs by eliminating unnecessary vibration.
Significance
Sound-deadening materials are used in many applications including vehicle interiors to deaden engine sound and vibration, to increase the range of stereo systems and to decrease rattling, road and exhaust noise. One such material is the B-Quiet Ultimate (see Resources) made of lightweight viscoelastic supercharged with a butyl-based adhesive, making light work of sound-deadening your vehicle.
Benefits
One layer of Acoustiblok (see Resources) works better to deaden sound than two 5/8th thicknesses of drywall each side of the wall, saving money, time and effort in your sound deadening interior wall projects. Noise complaint litigation is considerably reduced using one application of Acoustiblok instead of multiple layers of drywall in a feeble attempt to deaden sound. Additional bonuses to using this particular sound-deadening material are that it has thermal insulation value, it is not subject to water damage and it is lighter than most products manufactured for sound-deadening.
Function
Alsnetbiz (see Resources) has a special latex-based paint that insulates and deadens sound in the mid-range by 30 percent. Cork tiles are another effective sound deadener, as they are composed of trapped air mixed in with the cork. Tack underlay to interior walls and to the insides of interior doors offers an inexpensive solution to sound problems.
Effects
DynoBox from Dynamat.com solves ceiling speaker problems and noise migrating through floors, ceilings and walls. Retro-fitable, DynoBox keeps noise in one room and prevents sound-waves traveling through boards into another room. These speaker enclosures retail at $169.
Features
Sound-deadening boards may be purchased from any home improvement center and applied to the inside of the interior studs for effective sound-deadening qualities. Glue panels onto studs using a zigzag application of adhesive. Soundboard should be screwed in securely to prevent sound-loss.
