Perceptual Audio Evaluation - Theory, Method and Application

Beschreibung

As audio and telecommunication technologies develop, there is anincreasing need to evaluate the technical and perceptualperformance 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 areoften highly non-linear. This means that the auditory quality ofsuch systems cannot be measured by traditional physical measures(such as distortion, frequency response etc.), but only byperceptual evaluations in the form of listening tests. Perceptual Audio Evaluation provides a comprehensiveguide to the many variables that need to be considered before,during and after experiments. Including the selection of thecontent of the programme material to be reproduced, technicalaspects of the production of the programme material, theexperimental set-up including calibration, and the statisticalplanning of the experiment and subsequent analysis of the data. Perceptual Audio Evaluation: * Provides a complete and accessible guide to the motives, theoryand practical application of perceptual evaluation of reproducedsound. * Discusses all the variables of perceptual evaluation, theircontrol and their possible influence on the results. * Covers in detail all international standards on the topic. * Is illustrated throughout with tables, figures and workedsolutions. Perceptual Audio Evaluation will appeal to audio andspeech engineers as well as researchers in audio and speechlaboratories. Postgraduate students in engineering or acoustics andundergraduate students studying psychoacoustics, speech audioprocessing and signal processing will also find this an essentialreference.
