Acoustic room e.g. recording studio, for e.g. musical show, has panels in their closed positions closing absorption chambers, where admission of sound in absorption chambers is made possible in opened position

摘要

The room (1) has multi disks (12) formed as flat panels (6), and absorbing parts formed as absorption chambers, which have a spatial depth behind a reflecting part. The panels in their closed positions close the absorption chambers, where admission of the sound in the absorption chambers is made possible in an opened position. The disks in the closed position cover the absorbing parts and form a delimitation surface reflecting impinged sound.
