FREE-FIELD CHAMBERS
Free-Field Chamber
A free-field chamber is an approximation of a hemi-anechoic chamber. Rather than carrying anechoic wedges on the walls and ceiling, the chamber walls and ceiling are treated with several inches of glass fiber or a similar sound absorbing material. Small rooms and those intended for low frequency testing require a thicker layer, large rooms, and those intended for high frequency sometimes have sound absorption treatments as thin as 3 in.
