ABSTRACT:
A sound-absorbing building component for indoor paneling consisting of at least two superimposed sheets, preferably made of a synthetic resin. At least one of the sheets is provided with cup-shaped indentations lying side-by-side in the manner of a grid, the bottom surfaces of these indentations being excitable to lossy vibrations upon the incidence of sound. The upper rims of the cup-shaped indentations are all covered by a further planar sheet which is likewise capable of vibrations. This further sheet seals off the air volumes contained in the individual cup-shaped indentations in an airtight fashion. Small lumpy or irregularly-sized bodies can be provided on the bottom surfaces of the cup-shaped indentations.
