By determining the transmission attenuation of components or sealing elements, we can make precise statements about the attenuation behaviour
The combination of our semi-anechoic chamber (NRreverberation chamber enables us to carry out sound transmission measurements in a window test rig .
A homogeneous sound field is generated in the reverberation chamber and the remaining signal is measured on the receiving side. By means of 2 microphone technology, the transmission attenuation und the remaining coherence can be determined very well.
In our window test rig, acoustic leakage tests and sound penetrations, for example on doors or vehicle parts, can be carried out up to a dimension of 2 x 2.2m.
- Semi-anechoic chamber 7m x 10m; free-field radius accuracy class 1
- Reverberation chamber 5m x 3m
- Window test rig opening: 2m x 2.2m
- Installation of complete vehicle parts in the window test rig
