1. An acoustical diffuser for diffusing sound having a range of frequencies from a lowest frequency to a highest frequency, comprising:

  • a panel having a plurality of wells formed thereon;

    wherein the wells each have particular width equal to the speed of sound divided by the product of two times the lowest frequency and the wells each have different particular depth equal to a value of a quadratic residue number theory sequence, n2 (modulus), multiplied by a constant equal to the frequency wavelength of the lowest frequency divided by the product of two times the modulus, wherein the modulus is a lowest prime number exceeding a quotient of the highest frequency divided by the lowest frequency and n is equal to each integer from 0 to the modulus minus 1.
