	The secondary sound system consists of a 24 channel Motu 24Ao USB audio sound processor, three 4 channel Behringer EPQ304 audio amplifiers, and 12 wall mounted Cambridge audio Minx Min12 speakers. The purpose of the speaker wall is to provide background noise to the moving sounds produced by the speaker(s) on the arm.

The purpose of the speaker wall is to provide background noise to the moving sounds produced by the speaker(s) on the arm.
			The distance of the wall to the center of the booth is 145 cm.

	The speakers are connected via 2 lead wires for the sound and 3 lead wires for the LED's.		The speakers are connected via 2 lead wires for the sound and 3 lead wires for the LED's.

			One speaker kan rotate in two dimensions (azimuth, elevation) the other only in one dimension (azimuth). The angle between the speakers is always 90 degrees.
			The distance of the speakers to the center of the booth (= center of the head of the subject) is 120 cm.

	The sound booth is an acoustically isolated room with sound absorbing materials on all walls and the floor to reduce reverberation. A 2.~~4 m diameter quarter sphere build~~ of ~~a metal structure holds 43 small passive speakers~~. The speakers also contain two color LED's. In the center of the booth there is a chair for a subject. The chair is placed in a way that the head of the subject is right in center of the sphere.		The sound booth is an acoustically isolated room with sound absorbing materials on all walls and the floor to reduce reverberation. A robot arm rotates one speaker in two dimensions (azimuth and elevation) and one speaker in one dimension (azimuth). Both have a distance of 120 cm to the centre of the booth. The speakers also contain two color LED's. In the center of the booth there is a chair for a subject. The chair is placed in a way that the head of the subject is right in center of the sphere.
	Large coils are embedded in the walls of the sound booth. The coils make a box of about 2.5 m x 2.3 m x 2.8 m. These coils are used for head movement detection.
