The ITU-R Recommendation BS.1116 provides an important standard for the conduct of tests subjectively assessing high-quality audio coders. Nonetheless, a review of some results from psychophysics and human factors engineering in this paper suggests various refinements that could adapt the methodology to better match human capabilities.

3. Subjective assessment methods 3.1. General The method described below has been developed to assess the quality of “classical music” pro-grammes: symphonic music, orchestral music, choral music, opera, chamber music and solo per-formances. The method may also be applied to other types of “acoustic” music.

This Recommendation describes a method for the subjective assessment of intermediate audio quality. This method mirrors many aspects of Recommendation ITU-R BS.1116 and uses the same grading scale as is used for the evaluation of picture quality (i.e. Recommendation ITU-R BT.500). The method, called “MUlti Stimulus test with Hidden Reference and Anchor (MUSHA)”, …

An alternative methodology for subjective testing is based on an inverted scale that categorizes levels of impairment [21, 22] (very annoying, annoying, slightly annoying, perceptible but not annoying, and imperceptible). Our quantitative discussion of image and video quality will only be impressionistic, however, given the multidimensionality of the problem (dependence of …
