ETS-Lindgren's Hemi-Anechoic Chambers provide a precise free-field environment used to measure sound sources over a reflecting plane. Typical measurements include product noise testing, sound power, sound source frequency response, and sound source directivity.
ETS-Lindgren's Hemi-Anechoic Chambers provide engineered features that achieve outstanding acoustic testing performance results and goals without compromising acoustic concepts and budgets.
Hemi-anechoic chambers are used to perform precision- and engineering-grade testing on a wide variety of devices ranging from handheld units to large vehicles and equipment.
ETS-Lindgren's hemi-anechoic chambers are acoustic enclosures with 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 hemi-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.
