Cooperation on the design of the membrane ceiling with Hans Walter Müller Sound is projected and reflected from eight columns onto the ceiling. In each of the four ceiling elements, sized 3 x 5m, a plastic membrane is fitted at the lower edge of the frame. By means of pneumatic and mechanical forces the membrane transforms into an undulating surface. Vaults in motion. By sucking up the air pressure the membrane vaults up into a barrel shape: the sound is spatially focused. Increasing the air preessure causes the horizontally stretched membrane to curve downwards into the space like a cushion: the sound is scattered in the reflection. Each of the four fields has a vertically controllable metal calotte mounted in its centre. A lowered calotte and a simultaneously upwardly suctioned membrane-barrel transform the ceiling membrane into a dripstone ceiling configuration.   The ceiling itself has a molecular memory: after the curving forces of the arches come to an end, the membrane slowly returns to its original shape, into its stretched horizontal form. Each column bears an upwardly directed sound source. Electronically controlled sound movements between the sound capitals overlap, interweave in the space through changing surfaces of the programmed acoustical ceiling.
