    • 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 are unique in that they provide a flat power spectrum and constant scattered energy in the diffraction directions.

    • Disclosed are a variety of structural acoustical cinder blocks including locking blocks which are intended to 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, for example, the quadratic-residue sequence developed by Karl Frederick Gauss. The surface irregularities formed in the blocks are unique in that they provide a flat power spectrum and constant scattered energy in the diffraction directions. Each of the blocks including wells also includes a low frequency sound absorbing chamber. The blocks are installed such that there is a stacked bond on the diffusing face and a running bond on the structural rear face. If desired, a single block may be made which includes an entire sequence of wells and dividers.

    • Disclosed herein is an improved sound absorbing diffusor device wherein the surface designed to face the sound source includes a plurality of sound absorbing wells of equal widths but different depths separated by thin sound absorbing dividers. The depths of the individual wells are based upon the quadratic-residue number theory sequence which is used in acoustic design. The wells are covered with an open weave fabric adhered thereover which fabric is specifically chosen for its ability to allow sound to pass therethorugh to the wells and dividers. Tests performed on the inventive sound absorbing diffusor have revealed significant reduction in sound levels of reflected sounds over that which would accrue from a flat absorptive panel.
    • 本文公开了一种改进的吸声扩散器件,其中设计成面对声源的表面包括多个相同宽度但不同深度的由薄吸音分隔器隔开的吸声阱。 各孔的深度基于声学设计中使用的二次残留数理论序列。 这些井覆盖着粘附在其上的开放编织织物,该织物被特别选择为允许声音通过井和分隔器的能力。 对本发明的吸声扩散器进行的测试已经显示出反射声音的声级比由平面吸收面板产生的声音水平显着降低。
