The fully anechoic chamber features six surfaces madeup of Sola metal panels and sound-absorbing wedges on the walls, floor and ceiling. The basic anechoic chamber construct using concrete, plasterboard, and a special cloth-type sound-absorbing wedge. Our anechoic chamber, on the other hand, has the benefits of being simple to assemble, inexpensive, precise, and portable.
An anechoic chamber is a precision acoustical measurement instrument designed to create a free-field environment without reflections and noise interference. Ideally, the inverse square law applies perfectly, with sound levels from a spherical source decreasing by 6dB for each doubling of distance. This requires the room’s boundaries to have a sound absorption coefficient of one at all angles. While real-world applications may have slight deviations, these chambers minimize sound reflections with acoustically absorbing materials on all six surfaces.
