Abstract
The modular anechoic panel system provides modular anechoic panel for construction of anechoic chambers particularly advantageous for use in sound testing and measurement. The modular anechoic panel incorporates into a single structural member the elements of structural support, transmission loss features, and the wedge base and air space elements of an anechoic wedge thus providing enhanced protection to elements of the anechoic wedge. The modular anechoic panel provides a durable structural member and, as assembled, form a structural shell of an anechoic chamber having a reduced footprint. Additionally, the modular anechoic panel provides a compression clip mounting system for conveniently mounting and replacing wedge tips, thus allowing for use of standard wedge tip materials and easy assembly, repair and replacement of damaged wedge tips. The wedge is preferably formed of perforate sheet metal having a void ratio of greater than 52%, and more preferably 63%, and is packed with sound absorptive material, such as fiberglass.
