Test and evaluation of different passive damping materials on a laboratory test bench designed within the project

The market on passive damping material is very diverse. That means there exist a huge number of providers for such damping materials with a lot of different product each. Within the NOISELESS project, different passive damping materials have been analysed with respect to their dynamic and acoustic effectiveness. Attention was laid onto the fact, to test a wide range of different product classes. Those passive damping materials have been tested on a 1:1-scale laboratory demonstrator under constant conditions in an anechoic room. Like this it was possible to determine the best passive damping material for different application purposes. For instance in the case of the press, different damping material was used for the front cover panels and the panels of the columns.
