MALIK ARSHAQ WHY DO I NEED bass traps? Have you ever mixed in your studio on your monitors and felt that the mix was perfect, only to find out that it was severely lacking bass when you played it on your car’s speakers? This is probably because you misconceived, probably over estimated, the intensity of your low-end due to bass buildup in your room. Bass absorption is the key to a tight and balanced sound for a home studio. Most domestic small and mid-sized rooms with orthogonal edges (which is most rooms) have extremely uneven low frequency response. Without controlling the bass sounds, everything that you hear which falls in the range below 300Hz, is violently distorted by acoustical chaos caused by the geometry of the room, ruining the accuracy of the sound that you perceive. Bass sounds gather and build up the strongest in the corners of your room, and especially compounds in the three surface (trihedral) junctions. First place the bass traps in these junctions, then consider the two surface corners (wall-ceiling, wall-wall, and so on). The more the bass absorbers you are able to place, the flatter and tighter the low end response will be. Broadly, there are two types of absorbers. Porous (or frictional) absorbers, act on the velocity component of the sound, these slow down the air particles that carry the sound, thus they don't work on low frequencies unless they are enormously thick, or placed adequately far away from the wall. They are effective for absorbing even mid-high end frequencies, giving your mix a dryer sound. They are cheap, easily available and with a little trial and error, they are easy to install on your own. Resonant absorbers act on the pressure component of the sound, maximizing sound absorption where the pressure is maximum - a flat wall or ceiling. They are specifically built for bass frequencies. Used predominantly in high-end studios, they are to be set up by a professional, tuned to a specific room. If you can't fit every corner of the room with bass traps, prioritize by determining which corners have the most bass buildup, you can find many simple ways of doing this, even a few free softwares. Be wary, though, of sucking all the liveliness out of your sound, if you apply too many bass traps, as they can add to the absorption of mid-high end frequencies. In conclusion, proper bass control will enhance your listening experience and bring to light the finer details of your mix previously hidden by your boomy low end sound. 44 The Score Magazine highonscore.com
