Acoustics: Sound Fields and Transducers


Book Description

Acoustics: Sound Fields and Transducers is a thoroughly updated version of Leo Beranek's classic 1954 book that retains and expands on the original's detailed acoustical fundamentals while adding practical formulas and simulation methods. Serving both as a text for students in engineering departments and as a reference for practicing engineers, this book focuses on electroacoustics, analyzing the behavior of transducers with the aid of electro-mechano-acoustical circuits. Assuming knowledge of electrical circuit theory, it starts by guiding readers through the basics of sound fields, the laws governing sound generation, radiation, and propagation, and general terminology. It then moves on to examine: - Microphones (electrostatic and electromagnetic), electrodynamic loudspeakers, earphones, and horns - Loudspeaker enclosures, baffles, and waveguides - Miniature applications (e.g., MEMS in I-Pods and cellphones) - Sound in enclosures of all sizes, such as school rooms, offices, auditoriums, and living rooms Numerical examples and summary charts are given throughout the text to make the material easily applicable to practical design. It is a valuable resource for experimenters, acoustical consultants, and to those who anticipate being engineering designers of audio equipment. - An update for the digital age of Leo Beranek's classic 1954 book Acoustics - Provides detailed acoustic fundamentals, enabling better understanding of complex design parameters, measurement methods, and data - Extensive appendices cover frequency-response shapes for loudspeakers, mathematical formulas, and conversion factors

Physical and Applied Acoustics


Book Description

Physical and Applied Acoustics: An Introduction explores the mechanical-acoustical or acoustical-electrical analogies that are based on common theoretical relationships. This book is composed of 11 chapters that discuss the theory, experiment, and technological applications of physical and applied acoustics. The introductory chapters deal with the sound wave propagation in liquids and gases, as well as the statistical theory of room acoustics. These topics are followed by discussions on sound absorption in different medium; the concept of sound radiation pressure; directional characteristics of sound sources; measurement and calibration of acoustics; and the fundamental physical and psychological facts of acoustics. The subsequent chapters cover the use of electroacoustics for the transmission of speech and music. A chapter examines the production and detection of extremely high-frequency sound, called quantum acoustics. The concluding chapter highlights the interaction phenomena between sound and flow in a medium.




Sound Reproduction


Book Description

Sound Reproduction: The Acoustics and Psychoacoustics of Loudspeakers and Rooms, Third Edition explains the physical and perceptual processes that are involved in sound reproduction and demonstrates how to use the processes to create high-quality listening experiences in stereo and multichannel formats. Understanding the principles of sound production is necessary to achieve the goals of sound reproduction in spaces ranging from recording control rooms and home listening rooms to large cinemas. This revision brings new science-based perspectives on the performance of loudspeakers, room acoustics, measurements and equalization, all of which need to be appropriately used to ensure the accurate delivery of music and movie sound tracks from creators to listeners. The robust website (www.routledge.com/cw/toole) is the perfect companion to this necessary resource.
