Abstract: Sixteen-millimeter soundtrack tests were conducted to determine the carrier frequency of cross-modulation signals that would correlate best with listening tests and the maximum amount of cross-modulation distortion that would be acceptable to listeners. Results show that a carrier frequency of 8.5 kHz should be used for cross-modulation tests on 16mm films and that 3% cross-modulation distortion (-30-dB cancellation) is probably a reasonable maximum distortion for acceptable soundtrack quality.
