Bass traps to controll low frequencies In a listening room or studio, low frequencies, also called bass tones, can produce standing waves. In simple terms, this means that a sound wave fits exactly into a room, so that a hum can be perceived. To find a solution, avoiding complicated and often costly noise measurements, you can reduce this problem by installing Bass Traps in the corners of your room.
Where do I place bass traps? The most obvious places are of course the corners, hence the triangle shape. It depends on the frequencies and the place where the standing wave originates. Our advise is to first equip the corners in the front of the room with bass traps, at least 2 per corner to achieve sufficient absorption volume. At a later stage you can also equip the corners behind the seating position with bass traps.
If you have a space that is relatively empty in terms of furniture and decor, you also place bass traps in the corners of the wall and ceiling (in the middle of a wall). By doing this, you bring enough volume into the room. Placing a big record cabinet or sofa in the room also provides a sufficient result in some cases!
Make bass traps yourself The DIY studio builder or audiophile can try to make his own absorption panels or bass traps. By means of wooden frames covered with a type of textile, you fill corners in such a way that standing waves are deflected, making sure low-frequency sound won't dominate. A mix of Akotherm Basic D20 and D40 is the perfect filling. Place a number of low Akotherm D40 on top of the lighter variant Akotherm Basic D20 for an optimal result. Bass traps must be filled well to function properly.
