Acoustic Test Stands

Engine and Powertrain testing is typically carried out inside a hemi-anechoic chamber to ensure high acoustic absorbency. A typical layout for test cells is with independent dynamometers sitting outside of the test chamber, leaving only the engine and gearbox inside the hemi-anechoic room.

Pass by chambers

Vehicle pass-by noise tests are conducted according to the international standard ISO 362, which quantifies the noise emission of a vehicle in an urban traffic environment, by testing on an outdoor track.

Reverberation Chambers

A reverberation chamber can be considered the opposite of a an anechoic chamber because its boundaries reflect, rather than absorb sound energy.
