This product comesAcoustic enhancement The objective is to enhance the properties of sound by improving speech clarity and sound quality. For this reason, acoustic foam is often used in recording studios. The purpose is to reduce, but not entirely eliminate resonance within the room. This is achieved by placing similar sized pieces of foam, often in the shape of cones or triangles, on opposite walls. Acoustic foam reduces or eliminates echoes and background noises by controlling the reverberation that sound can make by bouncing off walls. Acoustic foam typically deals more with the mid and high frequencies. To deal with lower frequencies, much thicker pieces of acoustic foam are needed; large pieces of acoustic foam are often placed in the corners of a room and are called acoustic foam corner bass traps. The depth of this foam provides better soundproofing over large areas. Thin foam, over a large area, has less of a chance of distorted and muffling the sounds reverberation. The uniform wedge design help trap airborne noise while alleviating flutter echo and slap back. This foam is ideal for spot-treating production studios, practice rooms or home entertainment centers. Also, this foam helps with smaller agitation echo complications. It is tested to effectively eliminate sound waves and flutter. Purchasing your own foam is the best way to tune your area without hiring a professional acoustician. This Foam will not deteriorate or fall apart over time. All that is required is dusting over long periods of time.
