H5-16: OHM'S LAW OF HEARING - FOURIER SYNTHESIZER

PURPOSE: To 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.

SUGGESTIONS:

REFERENCES: (PIRA unavailable.)

EQUIPMENT: Fourier Synthesizer with speaker and oscilloscope on scope/TV cart.

SETUP TIME: 5 min.
