There are two types of bass traps: resonating absorbers and porous absorbers. By their nature resonating absorbers tend toward narrow band action (absorb only a narrow range of sound frequencies), and porous absorbers tend toward broadband action (absorbing sound all the way across the audible band – low, mid, and high frequencies). Though both types can be altered to be either more narrow, or more broad in their absorptive action.
Porous absorbers are most commonly made from fibreglass, mineral wool or open cell foams they have small pores in the medium. The small pores capture pockets of air to the room which when excited by sound pressure waves in the room’s air volume are themselves induced to vibrate like small springs.
Low-frequency pressure builds up wherever there is a boundary. Each room dimension has two boundaries which are parallel to each other such as the corners of a room.
An acoustic panel is most effective at eliminating high-frequency noise while treating low-frequency noise problems requires thicker bass traps.
Acoustafoam is proud to offer acoustic bass trap kits with various profiled faces which are ideal to be fitted into music studios. They work as acoustic energy absorbers which are designed to damp low-frequency sound energy.
Our acoustic bass trap kits are now available in four different styles and three different colours with the option to have a self-adhesive sticky back to stick to walls.
