The first rule of soundproofing is to A) Block the sound and B) Absorb the sound you just blocked. Most heavy wall soundproof projects tend to violate the first rule of soundproofing. Like the racquetball court, they block the sound but don’t absorb the sound they just blocked. There is a huge difference between condo soundproofing projects and high power audio soundproofing projects: Bandwidth. Today’s audio systems play sound ranging between 25 Hz and 20k Hz. The STC standards that are commonly cited in soundproofing projects only range between 100 Hz and 4k Hz. They only apply to speech sound range. They do not address the lower two octaves or the upper two octaves in the musical bandwidth
Our outer wall system blocks the bass and the inner wall system absorbs the bass that just got blocked
The ASC Iso-Wall builds upon a proven soundproofing method called resilient channel to isolate the interior walls of a room. We improved on the isolation by adding low frequency sound damping and vibration control.
Installed in hundreds of high end audio rooms, the result is the only soundproofing system engineered for high volume audio playback.
By utilizing our proprietary WallDamp material (a visco-elastic polymer) throughout the system, low frequency sound energy is absorbed into the wall. This reduces bass feedback and shuddering walls, and results in a clean, rich sound with well-balanced frequency response. If you have a home theater or studio, and you need to run cables through your soundproofed wall, consider the ASC Cable Pass Through Kit. The ASC Iso-Wall comes as a complete kit and is designed to be affordable and easy-to-install by any contractor or the do-it-yourself homeowner.
In high power audio applications, the interior surface of the room can no longer be used as a sound proofing element. It is converted into an isolation wall that has damping added. It becomes a giant membrane bass trap for the subwoofer range of sound while continuing to load the woofer bass range of sound and softening major room modes.
The soundproofing component, if needed, is a specially constructed, bass proof wall located on the other side of the interior working wall.From simple soundproofing projects to complex professional sound conditioning/proofing projects, we continue to develop and provide the products, engineering services and project materials needed to get your job done right…right, the first time.
