Definitions for "Intermodulation distortion"
Impairment created when two frequencies interact to create an erroneous frequency, in turn distorting the data signal representation.
Distortion generated by the faulty mixture of different input frequencies. This is a primary cause of harshness and lack of intelligibility in a hearing aid.
(in loudspeakers) Is the distortion generated in single cone speakers when the cone is reproducing a high and low frequency simultaneously. The high frequency peaks will be flattened off if the low frequency is distorted in any way. also see: AKA: Antonym: Source: http://www.the12volt.com/glossary/glossary.asp
