The '''acoustic pi''', the transcendental number equal to the [[ratio]] of a circle's circumference to the diameter, is about 3.14159, a rather minor thirteenth of 1981.795 [[cent]]s. It is unclear what psychoacoustic significance this interval might have. | The '''acoustic pi''', the transcendental number equal to the [[ratio]] of a circle's circumference to the diameter, is about 3.14159, a rather minor thirteenth of 1981.795 [[cent]]s. Octave-equivalent intervals include '''acoustic tau ('''3181.795 [[cent]]s) and '''reduced acoustic pi''' (781.795 cents).
