Purpose:Validate Ohm's Law of Hearing for a simple case.
Description:Form a complex tone from the first and second harmonics, with the amplitude of the second harmonic about half that of the first and a fundamental frequency of about 200-500 Hz. Changing the phase of the second harmonic changes the wave shape but leaves the sound virtually unchanged. This is Ohm's Law of Hearing: That the relative phase of components of a sound is, under normal circumstances, undetectable to our ears. Like Ohm's law of electrical resistance, it is not a universal law of nature, but a description relevant to many common phenomena.
