Acoustic diffuser panel system and method

Abstract

An acoustic diffuser panel for diffusing sound of a range of frequencies comprises a sound reflective surface having a plurality of generally parabolic shaped wells interconnected by arcuate junctions. The shaped wells are bounded by an outer lip. The sound reflective surface of the panel is generally curvilinear. The number of wells of the panel is equal to a modulus. The modulus is the lowest prime number exceeding the quotient of the highest frequency of the range of frequencies divided by the lowest frequency of the range of frequencies. The wells at their opening each have particular width less than or equal to the quotient of the speed of sound divided by the product of two times the lowest frequency of the range of frequencies. Each well has a depth equal to a value of a quadratic residue number theory sequence, n.sup.2 (modulus N), multiplied by a constant equal to the frequency wavelength of the lowest frequency divided by the product of two times the modulus, wherein n is equal to each integer from 0 to N-1. The acoustic diffuser panel is manufacturable as a single integral unit by molding.
