Envirotech Metallic Anechoic Wedges are designed for cut-off frequencies as per testing requirements. Metallic wedges provided excellent sound absorption over a wide frequency range and provide required testing requirements for achieving noise level & cut-off frequency inside. The wedges are infilled with sound-absorbing layers with a combination of high density in the base & low density in its tip/peak.
The metallic anechoic wedges are designed for semi-anechoic chambers / anechoic chambers. Envirotech Systems is a manufacturer of anechoic chambers, semi-anechoic chambers, and metallic wedges. The product is utilized for components/ complete products in industries like Automobile, HVAC, Audio, etc.
