Abstract

The subjective effects of controlled high frequency limitation of the audio bandwidth on assessment of audio quality were studied. The investigation was focused on the standard 5.1 multichannel audio set-up (Rec. ITU-R BS.775-1) and limited to the optimum listening position. The effect of video presence on audio quality assessment was also investigated. The results of the formal subjective test indicate that it is possible to limit the high frequency content of the centre or of the rear channels without significant deterioration of the audio quality for some of the investigated programme material types. Video presence has small effect on audio quality assessment.
