What are Bass Traps?

Bass traps are acoustic energy absorbers that are designed to dampen 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.
