So your neighbors don’t hear your vibrating walls, but what are you listening to?
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.
People who build high performance audio rooms — home theaters, audiophile listening rooms and recording studios — need to keep inside sounds from getting out and outside sounds from getting into their room. That type of work is called soundproofing. One of the most soundproof rooms is your local racquetball court. The walls are so hard and thick that the sound can’t get out of the room, and so, it stays in the room, which is why the room is so reverberant. It would be impossible to put a high power audio playback system in a racquetball court and get the room to ever sound right. On the other hand most ordinary rooms may not be very soundproof but they certainly sound better than a racquetball court.
The high performance audio room owner wants a room that both sounds great and is soundproof. We have been helping people build their audio playback rooms since 1988. We have to build a room within a room to get audio playback rooms to sound right. The inner room is flexible like most good sounding rooms while the outer room is rigid, heavy and strong so the bass cannot escape. In our work, soundproofing the outer walls is only half of the project, conditioning the interior walls, floor and ceiling of the room to address sound and vibration is also part of the project.
Our focus is not just on soundproofing rooms, a racquetball court can do that job along with most other soundproofing systems. We are dedicated to creating great sounding soundproof rooms. In fact, we pioneered the art and science of building small rooms that are to be used for high performance audio playback.
