Abstract
A cylindrical screen within which rotates a rotor fitted with means causing pressure variations and/or turbulence. The rotor (1) consists of one or several cylindrical surface segments (2) which when geometrically developed are right triangles of which the two perpendicular sides (3, 4) resp. correspond to the cylinder base (3) and to the height (4) and of which the oblique side (5) constitutes the hypothenuse.
