A Sound Absorbing Means Containing At Least One Cavity Resonator
Original language description
The invention relates to a sound absorbing means which contains at least one cavity resonator. The goal of the invention is achieved by sound absorbing means which contains at least one cavity resonator, whose principle consists in that on at least one of the surfaces of this cavity resonator is fixedly attached an acoustic resonant membrane, which overlaps an orifice/orifices leading into the cavity/cavities of the cavity resonator. The parameters of the resonant membrane together with the shape and volume of the cavity of the cavity resonator then determine which sound frequencies will be damped and to what extent. At the same time it is possible - while keeping the thickness of the resonator - to damp sound frequencies which could be normally damped by cavity resonator with extremely large air gap. No licence.
