H5-16. Ohm'S Law Of Hearing - Fourier Synthesizer
To validate Ohm's Law of Hearing for a simple case.
Fourier Synthesizer with speaker and oscilloscope on scope/TV cart.
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.
