Abstract

The audible threshold of transient intermodulation distortion (TIM) was determined for the six most sensitive subjects of the previously reported test series of 68 listeners. Improved equipment, carefully controlled listening environment, a digital TIM generator, and five recorded stereophonic music samples were used. The results show that in certain types and passages of music, a trained and sensitive listener can reliably detect extremely low values of distortion. Low distortion values were perceived only as changes in the sound character, and not as distortion.
