Perceptual Audio Evaluation - Theory, Method and Application


Book Description

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.

Communication Acoustics


Book Description

In communication acoustics, the communication channel consists of a sound source, a channel (acoustic and/or electric) and finally the receiver: the human auditory system, a complex and intricate system that shapes the way sound is heard. Thus, when developing techniques in communication acoustics, such as in speech, audio and aided hearing, it is important to understand the time–frequency–space resolution of hearing. This book facilitates the reader’s understanding and development of speech and audio techniques based on our knowledge of the auditory perceptual mechanisms by introducing the physical, signal-processing and psychophysical background to communication acoustics. It then provides a detailed explanation of sound technologies where a human listener is involved, including audio and speech techniques, sound quality measurement, hearing aids and audiology. Key features: Explains perceptually-based audio: the authors take a detailed but accessible engineering perspective on sound and hearing with a focus on the human place in the audio communications signal chain, from psychoacoustics and audiology to optimizing digital signal processing for human listening. Presents a wide overview of speech, from the human production of speech sounds and basics of phonetics to major speech technologies, recognition and synthesis of speech and methods for speech quality evaluation. Includes MATLAB examples that serve as an excellent basis for the reader’s own investigations into communication acoustics interaction schemes which intuitively combine touch, vision and voice for lifelike interactions.




Robotics in Education


Book Description

This book comprises the latest achievements in research and development in educational robotics presented at the 13th International Conference on Robotics in Education (RiE), which was carried out as a purely virtual conference from April 27 to 28, 2022. Researchers and educators will find valuable methodologies, experiences, and tools for robotics in education that encourage learning in the fields of science, technology, engineering, arts, and mathematics (STEAM) through the design, creation, and programming of robots addressing real-world societal needs. Social robotics is becoming an important topic in education as well. This also involves various modern technologies ranging from robotics platforms to programming environments and languages. Many papers also prove the positive impact of robotics on the students’ interests and competence development. The presented approaches cover the whole educative range from kindergarten to the university level and lifelong learning.




The Oxford Handbook of Sound and Imagination


Book Description

In this two-volume Handbook, contributors address the tendency to discuss musical imagination through terms like compositional creativity or performance technique, correcting the current bias towards visual imagination to instead highlight the many forms of sonic and musical imagination.




The Oxford Handbook of Sound and Imagination, Volume 2


Book Description

Whether social, cultural, or individual, the act of imagination always derives from a pre-existing context. For example, we can conjure an alien's scream from previously heard wildlife recordings or mentally rehearse a piece of music while waiting for a train. This process is no less true for the role of imagination in sonic events and artifacts. Many existing works on sonic imagination tend to discuss musical imagination through terms like compositional creativity or performance technique. In this two-volume Handbook, contributors shift the focus of imagination away from the visual by addressing the topic of sonic imagination and expanding the field beyond musical compositional creativity and performance technique into other aural arenas where the imagination holds similar power. Topics covered include auditory imagery and the neurology of sonic imagination; aural hallucination and illusion; use of metaphor in the recording studio; the projection of acoustic imagination in architectural design; and the design of sound artifacts for cinema and computer games.
