Description

Bass traps are acoustic energy absorbers which are designed to damp low frequency sound energy with the goal of attaining a flatter low frequency (LF) room response by reducing LF resonances in rooms. They are commonly used in recording studios, mastering rooms, home theatres and other rooms built to provide a critical listening environment. Like all acoustically absorptive devices, they function by turning sound energy into heat through friction.

A basic bass trap is simply a deeper absorber. Low-frequency wavelengths are very long; in many cases, longer than the length or width of your room. For example, a 50Hz waveform has a wavelength of 6.8 metres. We cannot assume that a typical absorber, described above, with a shallow depth will soak up these wavelengths. To use absorption, we need to gain depth, and as bass often lurks in the corners of your room, enter the corner
