Pan Global Energy Acoustic Products India introduces Bass Trap Acoustic Foam. Pan Global Energy 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.Since low-frequency resonances in a room have their points of maximum or minimum pressure in the corners of the room, bass traps mounted in these positions will be the most efficient. Bass traps are typically used to attenuate modal resonances and so exact placement depends on which room mode one is trying to target. Bass traps typically combine structural mechanisms that can work at both positions of high particle velocity/low pressure (thick foam) and high pressure/low particle velocity (membranes).
