The present invention relates to a combination acoustic diffuser and
absorber and method of production thereof. The diffuser has an
acoustically reflective surface that may be made by the vacuum forming of
pliable sheet material in conformity with a shaped template and the
subsequent fixing of the resulting shape of said material, and which
surface includes a plurality of wells, the depths of which wells may be
determined by number theory sequences. The absorber may include one or
more tunable Helmholtz resonators which may be attached to the rear face
of the diffusing surface. The combination acoustic diffuser and absorber
may be optimized in its function and construction for use in a typical
residential application. A kit may also be provided that comprises a
diffuser, absorbers, mounting hardware, and assembly and adjustment
instructions.
