Soundproofing materials can be applied to a wall that’s under construction or be added to an existing wall, post-construction. There are several ways to soundproof a wall. Improvements in the soundproofing industry have resulted in products that are more effective and cost less than traditional wall soundproofing methods.
Recommended Wall Soundproofing Methods
Recommended soundproofing methods are less expensive and more effective than traditional methods.
Traditional, less effective methods
Traditional wall soundproofing methods are more expensive and less effective than the new technologies available today.
Adding a high density material to the structure of the wall significantly reduces the transfer of sound. At a fraction of the cost of traditional soundproofing methods, adding mass is a popular way to soundproof a wall.
The most efficient soundproofing method on the market today is sound isolation systems. Using sound isolation systems, a room can be completely isolated from an adjacent room, resulting in the best soundproofing possible
Sound travels through drywall along common studs. isoTRAX™ Soundproofing System, the most popular sound isolation system, works by “floating” a mounted wall over the studs. There are no common studs for sound to travel along, stopping the transfer of sound waves.
isoTRAX™ Soundproofing System is fastened to the studs without any direct contact between hardware and wood.isoTRAX™ Soundproofing System provides a peel and stick dampener to pad the studs when applying the metal tracks. Also, each track is equipped with neoprene foam to cushion your drywall from vibration.
This system is easy to install, increases wall strength, and provides top soundproofing quality.
In standard wall construction, studs connect two slabs of drywall. Noise easily travels along this connection. In a staggered stud wall construction, studs are connected to one side of the wall, but not the other. While this reduces noise transfer, it takes up extra space, involves expensive construction techniques, and weakens the structural integrity of the wall itself.
This method is often used in “room within a room” construction for studios and music practice rooms. When used with other soundproofing materials, double wall construction offers complete sound protection. However, double walls are expensive, hard to build, and take up room space.
Resilient channel is a spring metal track used to isolate a drywall panel from other wall construction. While this method provides reduced sound transfer, it’s very difficult to install. If not installed properly, it will not provide effective soundproofing. This method is even less effective when the building structure shifts or nails are driven into studs to hang items to the finished wall.
Batts are fitted between wall studs for acoustical protection. Fiberglass batts are light and thin, allowing noise to leak through. Without additional soundproofing materials, fiberglass batts are ineffective. Fiberglass materials work better for sound absorption (improving sound quality) than soundproofing.
