Anechoic Chamber
​​​ETS-Lindgren's Anechoic Chambers provide a precision-grade free-field environment used to measure sound source directivity, frequency response, and noise emissions from spherically radiating sound sources.

 

 


​​​​​ETS-Lindgren's Anechoic Chambers offer a precision-grade free-field environment used to measure sound source directivity, frequency response, and noise emissions from spherically radiating sound sources. These chambers provide engineered features that achieve outstanding performance results and goals without compromising acoustical concepts and budgets.

These anechoic chambers have a high-performance wall panel system that provides the low-noise environment required to test today’s low-noise products. A precision-grade free-field environment is a product of the anechoic chamber's sound absorption system that consists of melamine wedges installed on a patented clip system that provides fast wedge installation and removal. Unlike other wedge solutions, melamine wedges provide a bright and fiber-free working environment.
