Fully Anechoic Acoustic Chamber

MIL-STD 461 Chamber

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.
