Claims
- 1. An improved acoustical diffusor comprising:
- (a) a low frequency diffusor including a first plurality of wells, said wells being of particular depths with respect to one another which are determined by use of a quadratic-residue number theory sequence, wherein each consecutive well is given a number of 0 to n, where n equals one less than a total number of wells, and wherein a depth of any particular well is determined by squaring said number for said particular well and dividing said squared number by a chosen modulus number resulting in a remainder, the remainder after said dividing being multiplied by a chosen constant to arrive at said depth of said particular well; and
- (b) a plurality of high frequency diffusors corresponding in number to the number of wells of said low frequency diffusor, said high frequency diffusors each having a second plurality of wells and each being mounted in a respective one of said wells of said low frequency diffusor, said improved acoustical diffusor having characteristics of a fractal structure.
- 2. The invention of claim 1, wherein each second plurality of wells have depth determined through use of said quadratic-residue number theory sequence.
- 3. The invention of claim 1, wherein adjacent wells of said first plurality of wells are separated from one another by dividers.
