Benoit Mandelbrot (of mandelbrot set fame) is largely responsible for this. Apparently he invented the “special math equation” mentioned in an earlier post which helps cancel out interference with a specific sound wave.

At least that is my thoroughly lay understanding of it. The point is that Mandelbrot and the early research into fractal geometry were instrumental in fixing this problem.
