Techniques in Speech Acoustics


Book Description

Techniques in Speech Acoustics provides an introduction to the acoustic analysis and characteristics of speech sounds. The first part of the book covers aspects of the source-filter decomposition of speech, spectrographic analysis, the acoustic theory of speech production and acoustic phonetic cues. The second part is based on computational techniques for analysing the acoustic speech signal including digital time and frequency analyses, formant synthesis, and the linear predictive coding of speech. There is also an introductory chapter on the classification of acoustic speech signals which is relevant to aspects of automatic speech and talker recognition. The book intended for use as teaching materials on undergraduate and postgraduate speech acoustics and experimental phonetics courses; also aimed at researchers from phonetics, linguistics, computer science, psychology and engineering who wish to gain an understanding of the basis of speech acoustics and its application to fields such as speech synthesis and automatic speech recognition.




Foundations of Engineering Acoustics


Book Description

Foundations of Engineering Acoustics takes the reader on a journey from a qualitative introduction to the physical nature of sound, explained in terms of common experience, to mathematical models and analytical results which underlie the techniques applied by the engineering industry to improve the acoustic performance of their products. The book is distinguished by extensive descriptions and explanations of audio-frequency acoustic phenomena and their relevance to engineering, supported by a wealth of diagrams, and by a guide for teachers of tried and tested class demonstrations and laboratory-based experiments. Foundations of Engineering Acoustics is a textbook suitable for both senior undergraduate and postgraduate courses in mechanical, aerospace, marine, and possibly electrical and civil engineering schools at universities. It will be a valuable reference for academic teachers and researchers and will also assist Industrial Acoustic Group staff and Consultants. - Comprehensive and up-to-date: broad coverage, many illustrations, questions, elaborated answers, references and a bibliography - Introductory chapter on the importance of sound in technology and the role of the engineering acoustician - Deals with the fundamental concepts, principles, theories and forms of mathematical representation, rather than methodology - Frequent reference to practical applications and contemporary technology - Emphasizes qualitative, physical introductions to each principal as an entrée to mathematical analysis for the less theoretically oriented readers and courses - Provides a 'cook book' of demonstrations and laboratory-based experiments for teachers - Useful for discussing acoustical problems with non-expert clients/managers because the descriptive sections are couched in largely non-technical language and any jargon is explained - Draws on the vast pedagogic experience of the writer




Audio Technology, Music, and Media


Book Description

This book provides a true A to Z of recorded sound, from its inception to the present day, outlining how technologies, techniques, and social attitudes have changed things, noting what is good and what is less good. The author starts by discussing the physics of sound generation and propagation. He then moves on to outline the history of recorded sound and early techniques and technologies, such as the rise of multi-channel tape recorders and their impact on recorded sound. He goes on to debate live sound versus recorded sound and why there is a difference, particularly with classical music. Other topics covered are the sound of real instruments and how that sound is produced and how to record it; microphone techniques and true stereo sound; digital workstations, sampling, and digital media; and music reproduction in the home and how it has changed. The author wraps up the book by discussing where we should be headed for both popular and classical music recording and reproduction, the role of the Audio Engineer in the 21st century, and a brief look at technology today and where it is headed. This book is ideal for anyone interested in recorded sound. “[Julian Ashbourn] strives for perfection and reaches it through his recordings... His deep knowledge of both technology and music is extensive and it is with great pleasure that I see he is passing this on for the benefit of others. I have no doubt that this book will be highly valued by many in the music industry, as it will be by me.” -- Claudio Di Meo, Composer, Pianist and Principal Conductor of The Kensington Philharmonic Orchestra, The Hemel Symphony Orchestra and The Lumina Choir

Advanced Applications in Acoustics, Noise and Vibration


Book Description

Advanced Applications in Acoustics, Noise and Vibration provides comprehensive and up-to-date overviews of knowledge, applications and research activities in a range of topics that are of current interest in the practice of engineering acoustics and vibration technology. The thirteen chapters are grouped into four parts: signal processing, acoustic modelling, environmental and industrial acoustics, and vibration. Following on from its companion volume Fundamentals of Noise and Vibration this book is based partly on material covered in a selection of elective modules in the second semester of the Masters programme in 'Sound and Vibration Studies' of the Institute of Sound and Vibration Research at the University of Southampton, UK and partly on material presented in the annual ISVR short course 'Advanced Course in Acoustics, Noise and Vibration'.




Broadcast Sound Technology


Book Description

Broadcast Sound Technology (1995) covers the basic principles of all the main aspects of the broadcast chain, including microphones and loudspeakers technology, mixing consoles, recording and replay (analogue and digital) and the principles of stereo.




The Soundscape of Modernity


Book Description

A vibrant history of acoustical technology and aural culture in early-twentieth-century America. In this history of aural culture in early-twentieth-century America, Emily Thompson charts dramatic transformations in what people heard and how they listened. What they heard was a new kind of sound that was the product of modern technology. They listened as newly critical consumers of aural commodities. By examining the technologies that produced this sound, as well as the culture that enthusiastically consumed it, Thompson recovers a lost dimension of the Machine Age and deepens our understanding of the experience of change that characterized the era. Reverberation equations, sound meters, microphones, and acoustical tiles were deployed in places as varied as Boston's Symphony Hall, New York's office skyscrapers, and the soundstages of Hollywood. The control provided by these technologies, however, was applied in ways that denied the particularity of place, and the diverse spaces of modern America began to sound alike as a universal new sound predominated. Although this sound—clear, direct, efficient, and nonreverberant—had little to say about the physical spaces in which it was produced, it speaks volumes about the culture that created it. By listening to it, Thompson constructs a compelling new account of the experience of modernity in America.




Music, Sound, and Technology


Book Description

Since its publication in 1990, the first edition of Music, Sound, and Technology has enjoyed wide success and has become a popular text in musical acoustical studies at the university level. In preparing the new edition we have included recent developments in all aspects of music and sound technology, and we have added data on acoustical characteristics of musical in struments. The first edition has been cited for the scope and clarity of its graphics; we have emphasized this to an even greater degree in the second edition. /ME xi Preface to the First Edition This book is about music. the instruments and players who produce it. and the technologies that support it. Although much modern music is produced by electronic means. its underlying basis is still traditional acoustical sound production. and that broad topic provides the basis for this book. There are many fine books available that treat musical acoustics largely from the physical point of view. The approach taken here is to present only the fundamentals of musical phys ics. while giving special emphasis to the relation between instrument and player and stressing the characteristics of instruments that are of special concern to engineers and tech nicians involved in the fields of recording. sound reinforcement. and broadcasting. In order to understand musical instruments in their normal performance environments.
