Material validation

In addition to the room test benches, the ACC has a silencer channel for measurements of silencer baffles of up to 10m in length according to DIN EN ISO 11691 / DIN EN ISO 7235. A vibration test stand with periodically driven mass allows the characterisation of insulators of any kind and a combination of three differently dimensioned impedance tubes allows the determination of absorption coefficients according to DIN EN ISO 10534-2.
