Principles Of Musical Acoustics

Principles of Musical Acoustics focuses on the basic principles in the science and technology of music. Musical examples and specific musical instruments demonstrate the principles. The book begins with a study of vibrations and waves, in that order. These topics constitute the basic physical properties of sound, one of two pillars supporting the science of musical acoustics. The second pillar is the human element, the physiological and psychological aspects of acoustical science. The perceptual topics include loudness, pitch, tone color, and localization of sound. With these two pillars in place, it is possible to go in a variety of directions. The book treats in turn, the topics of room acoustics, audio both analog and digital, broadcasting, and speech. It ends with chapters on the traditional musical instruments, organized by family. The mathematical level of this book assumes that the reader is familiar with elementary algebra. Trigonometric functions, logarithms and powers also appear in the book, but computational techniques are included as these concepts are introduced, and there is further technical help in appendices.

An ideal text for advanced undergraduates, the book provides the foundations needed to understand the acoustics of rooms and musical instruments as well as the basics for scientists and engineers interested in noise and vibration. The new edition contains four new chapters devoted primarily to applications of acoustical principles in everyday life: Microphones and Other Transducers, Sound in Concert Halls and Studios, Sound and Noise Outdoors; and Underwater Sound.

Comprehensive and accessible, this foundational text surveys general principles of sound, musical scales, characteristics of instruments, mechanical and electronic recording devices, and many other topics. More than 300 illustrations plus questions, problems, and projects.

This book comprises twelve articles which cover a range of topics from musical instrument acoustics to issues in psychoacoustics and sound perception as well as neuromusicology. In addition to experimental methods and data acquisition, modeling (such as FEM or wave field synthesis) and numerical simulation plays a central role in studies addressing sound production in musical instruments as well as interaction of radiated sound with the environment. Some of the studies have a focus on psychoacoustic aspects in regard to virtual pitch and timbre as well as apparent source width (for techniques such as stereo or ambisonics) in music production. Since musical acoustics imply subjects playing instruments or singing in order to produce sound according to musical structures, this area is also covered including a study that presents an artificial intelligent agent capable to interact with a real ('analog') player in musical genres such as traditional and free jazz.

This Dover edition is an unabridged and corrected republication of the work originally published in 1956.

The history of musical instruments is nearly as old as the history of civilization itself, and the aesthetic principles upon which judgments of musical quality are based are intimately connected with the whole culture within which the instruments have evolved. An educated modem Western player or listener can make critical judgments about particular instruments or particular per formances but, to be valid, those judgments must be made within the appro priate cultural context. The compass of our book is much less sweeping than the first paragraph might imply, and indeed our discussion is primarily confined to Western musical instruments in current use, but even here we must take account of centuries of tradition. A musical instrument is designed and built for the playing of music of a particular type and, conversely, music is written to be performed on particular instruments. There is no such thing as an "ideal" instrument, even in concept, and indeed the unbounded possibilities of modem digital sound-synthesis really require the composer or performer to define a whole set of instruments if the result is to have any musical coherence. Thus, for example, the sound and response of a violin are judged against a mental image of a perfect violin built up from experience of violins playing music written for them over the centuries. A new instrument may be richer in sound quality and superior in responsiveness, but if it does not fit that image then it is not a better violin.

While the history of musical instruments is nearly as old as civilisation itself, the science of acoustics is quite recent. By understanding the physical basis of how instruments are used to make music, one hopes ultimately to be able to give physical criteria to distinguish a fine instrument from a mediocre one. At that point science may be able to come to the aid of art in improving the design and performance of musical instruments. As yet, many of the subtleties in musical sounds of which instrument makers and musicians are aware remain beyond the reach of modern acoustic measurements. This book describes the results of such acoustical investigations - fascinating intellectual and practical exercises. Addressed to readers with a reasonable grasp of physics who are not put off by a little mathematics, this book discusses most of the traditional instruments currently in use in Western music. A guide for all who have an interest in music and how it is produced, as well as serving as a comprehensive reference for those undertaking research in the field.

This book provides a comprehensive introduction to the subject of acoustics, including the principles of human perception of sound, sometimes called psychoacoustics. Acoustics and Psychoacoustics is ideal for students of music technology, sound recording, traditional music and acoustics, as well as engineers studying audio, multimedia and communications systems. Anyone who wants a practical understanding of how real musical sounds behave and are perceived in real spaces, will find this an accessible and interesting read. Subjects featured include: · Principles of sound · Human hearing and psychoacoustics · Musical timbre, pitch and loudness perception · Sound generation in musical instruments · Sound in different environments (architectural acoustics) · Processing sound electronically The book's second edition provides new material on wave motion, brass and woodwind instruments, forward and backward masking, an introduction to coding, and diffusion. Additional references and marginal notes explaining basic terms are provided to aid understanding.

His research interests include the analysis and synthesis of music, speech and singing, human hearing modelling and the use of computer displays in voice teaching. He is an active organist, choral singer and choral conductor. Dr James Angus was an instigator of the music technology courses at York, where he formerly lectured. He is now an independent consultant and researches in the area of acoustics, in particular diffuser design and audio signal processing. Acoustics and Psychoacoustics is part of the Focal Press Music Technology Series.
