Abstract
The present invention relates to an acoustical diffusor device which is made up of a plurality of specially designed and shaped cinder or concrete blocks which may be assembled together through the use of mortar to provide a diffusor of desired shape and configuration. Each diffusor includes a plurality of wells, the depths of which are determined through the use of number theory sequences, such as the quadratic-residue sequence developed by Karl Frederick Gauss. These surface irregularities arenique in that they provide a flat power spectrum and constant scattered energy in the diffraction directions.
Claims7
A cinder block modular diffusor comprising:
- (a) a plurality of cinder blocks, each of which includes a plurality of wells, said wells being of particular depths with respet to one another which are determined by use of a quadratic-residue number theory sequence, wherein each consecutive well is given a number from 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, each of said cinder blocks including at least a portion of a complete sequence of wells;
- (b) said cinder blocks being assembled together with mortar to combine together to comprise an integrated acoustical diffusor having said complete sequence of wells.
