As audio and telecommunication technologies develop, there is an
increasing need to evaluate the technical and perceptual performance
of these innovations. A growing number of new technologies (e.g. low
bit-rate coding) are based on specific properties of the auditory
system, which are often highly non-linear. This means that the
auditory quality of such systems cannot be measured by traditional
physical measures (such as distortion, frequency response etc.), but
only by perceptual evaluations in the form of listening tests.
Perceptual Audio Evaluation provides a comprehensive guide to the many
variables that need to be considered before, during and after
experiments. Including the selection of the content of the programme
material to be reproduced, technical aspects of the production of the
programme material, the experimental set-up including calibration, and
the statistical planning of the experiment and subsequent analysis of
the data. Perceptual Audio Evaluation: Provides a complete and
accessible guide to the motives, theory and practical application of
perceptual evaluation of reproduced sound. Discusses all the variables
of perceptual evaluation, their control and their possible influence
on the results. Covers in detail all international standards on the
topic. Is illustrated throughout with tables, figures and worked
solutions. Perceptual Audio Evaluation will appeal to audio and speech
engineers as well as researchers in audio and speech laboratories.
Postgraduate students in engineering or acoustics and undergraduate
students studying psychoacoustics, speech audio processing and signal
processing will also find this an essential reference.
