ABSTRACT:
A sound-absorbing structure is provided which comprises a plurality of sound-absorbing tiles or other elements fitted in position, filler cast between the elements so as to provide a substantially flat surface with the elements, and a monolithic rendering which is porous but extends over the substantially flat surface and provides a very smooth surface without significantly reducing the sound-absorbing properties of the elements.
