An anechoic test chamber equipped with broad-band compact absorbers (semi-anechoic chamber) is available for investigations of operational noise and functional sounds in cars and vans, as well as acoustic optimization of subsystems.
The chamber is completely decoupled from the surrounding building and is particularly suitable for the localization of sound sources (e.g. with microphone arrays). The chamber's internal dimensions amount to 9 m x 5 m x 4 m (l x w x h). The lower frequency limit is 125 Hz.
