This room is also constructed as a "box in box". Outer box (building) is concrete and inside a box build by customdesigned standard "noise-silencer-modules". This innerbox is placed on rubber-suspensions.

This room is designed & constructed so that its possible to create both multichannel (eg. 5.1) and stereo-setups with loudspeakers. This demands the room to fulfill both IEC 60268-13 and ITU-R BS.1116 so it'll be possible to create setups according t  ITU-R BS.775-1.

Drawings/sketches of the room can be found below, and there's also a copy of the commisioning report from 2001 (internal).

A number of different electrical connections to controlroom makes is possible to create setups with a minimum of hardware placed inside the room during measurements. Like other special rooms there is intercom and optional videosurveillance available.
