AES Convention 61 · Paper 1392 · November 1978

Abstract

The audible threshold of TIM was determined for 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 stereophonic music samples were used. The results show that in certain passages of music, 0.003% of distortion is clearly audible. Low distortion values were perceived only as changes in the sound character, and not as distortion.
