In an anechoic chamber no reflections from the walls, floor or ceiling are allowed. according to ÖNORM S 5035 and DIN ??? 99.5% of the radiated sound energy must be absorbed. Anechoic chambers are commonly used for experiments requiring acoustic 'free field' conditions. Therefore no standing waves can establish.
In connection with the anechoic chamber various instrumentation- and studio microphones as well as digital recording equipment from 2 up to 24 channels is available.

Mechanical Vibration Analysis
'Laser Lab' / Electronic Speckle Pattern Interferometrie
The ESPI System (Electronic Speckle Pattern Inferometry) offers a possibilty for optical analysis of instrument body vibration patterns.
High Speed Camera / Slow Motion Analysis
The camera can be used for the analysis of trajectories and for visualisation of the vibration pattern of musical instruments.
