ETS-Lindgren reverberation chambers provide a diffuse-field environment that enables sound absorption tests, sound power tests, and transmission loss studies to be performed.
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.
The sound absorption system consists of white melamine wedges installed on a patented clip system that provides fast wedge installation and removal. Melamine wedges provide a bright and fibre-free working environment.
ETS-Lindgren’s standard hemi-anechoic chambers are designed to comply with ISO 3745 free-field limits for both broadband and pure tone testing.
