The tendency of a space to maintain sound energy is quantified by its "reverberation". One could describe reverberation as a smooth, slowly decaying echo.
A sonic event occurring within a space possesses energy, and this energy will remain until some force acts upon it and converts it to another form of energy. Air particles serve to reduce sound energy, albeit at a very low rate. A sound occurring within a space will maintain its energy for more time if there exists very little sound absorbing material, and it will maintain its energy for less time if there exists a significant amount of evenly distributed sound absorbing material. Larger spaces normally possess more (longer) reverberation, which means that a sound occurring in that space will remain audible for a relatively long period of time (2-5 seconds). Small, highly absorptive spaces, such as anechoic chambers, will possess virtually no reverberation (<0.25 seconds). An extreme demonstration of the principle exists in the "reverb chamber," which is a small space with smooth marble walls, floor, and ceiling, and can possess reverberation times upward of 5-10 seconds.
TubeTrap, the original, archetypal bass trap, dating back to 1984, are set up in the corners of the room where they act like sonic shock absorbers. The bass trap part of the TubeTrap damps out excessive build-up of bass energy in the room and the built-in diffuser backscatters slap back, converting flutter echo into fine grained lateral ambience.
The AttackWall is a world class mixing environment. It's a free standing workstation that consistently produces the most amazingly clear sonic space you'll ever work in. The AttackWall produces a reliable, repeatable, and accurate sonic space in which to track, mix, and master, regardless of the room or speaker system.
Used all over the world, StudioTraps are based on the famous TubeTrap, and are a powerful and versatile tool for the recording industry. These Traps not only absorb sound energy, but create diffusion to give the room a more defined and natural sound. StudioTraps are available in a wide variety of colors.
The Quick Sound Field is a near field recording environment that allows you get the most sound you can into your mics. The QSF as we call it can transform the center of an ordinary room into a lush recording space. It works great for all types of recordings, from tracking drums and vocals in wide open spaces to close miking guitar amps in close quarters. The QSF lets you get more sound into your mics.
The SoundPlank is perfect for absorbing excess mid-range frequencies, while keeping the acoustics bright and alive. Reverberation and echo signals are controlled while a fine-grained, diffusive reflection pattern fills the room. The resulting acoustic signature is smooth and uniform throughout.
Retain the ambiance of hubbub, enhance the clarity of table top conversation and quiet intrusions from across the room. Perfect retrofit for restaurants and coffee shops, fellowship and activity halls, meeting and conference rooms and specialty rooms such as home theaters, museums, and art galleries.
With hundreds of hours of real world testing, ASC’s engineering and product development technicians have produced the best acoustical soffit available anywhere. Acoustic engineers have known for hundreds of years that a soffit is an excellent sound diffuser. ASC improved the idea to include absorption and custom room tuning.
The ASC CeilingPanel is another acoustic building block for creative architects and designers that are concerned with large room acoustic control. The science behind the CeilingPanel is simple: control of directional noise by creating an acoustic speed bump.
Built to interior design standards, it features bevel cut face, crisp corners and smooth finish, comes in a wide variety of a beautiful fabrics and is trimmed out by a paintable white picture frame. The ASC Sound Panel is completely finished on all sides, including the back.
