IAC builds semi-anechoic chamber for VDE

IAC Germany has built a 7.7m high semi-anechoic chamber for the country's VDE (Association for Electrical, Electronic and Information Technologies) testing institute.

The semi-anechoic chamber (SAS) is part of the VDE's EMC and acoustic test centre, and has a cut-off frequency of less than 80Hz.

It was built using a double wall panel construction, yielding an ambient noise level of below 12dB(A).

The vibration insulation of the inner shell is mounted on springs.

The floor is a concrete plate which also forms the base for the inner shell, while the outer shell rests on the building's foundation.

The overall size of the chamber is 15.5m x 13.5m x 7.7m high, with the interior lined with IAC's metal-coated Metadyne wedges.
