Abstract
The intermodulation test provides a measure of the distortion introduced by a sound system through its failure to reproduce two or more frequencies without interaction between them. The principles underlying the measurement of intermodulation are described, and procedures for testing both negative and positive films are outlined. Results representative of both standard and experimental stocks and processing are given. The interpretation of various families of intermodulation versus print density curves in terms of film characteristics is discussed. Test modifications required by the introduction of noise reduction bias and results obtained under such conditions are described. Application of the intermodulation test to 16-mm films is shown to require no fundamental change in the test procedure.
