Modern Room Acoustics will help to mitigate sound problems in rooms using acoustical principles and the constraints of time, budget and practicality. Practical room acoustics can be divided into two categories: less noise and better sound. Or, in acoustical terms, soundproofing and room treatments, which are described and solutions recommended.

Well established as a classic reference and specialised textbook, since its first publication in 1973, Heinrich Kuttruff’s Room Acoustics combines detailed coverage with a state of art presentation of the theory and practice of sound behaviour in closed spaces. This sixth edition presents several additional new sections, for instance on the reflection of a spherical wave from a wall, on finite element methods for sound field calculation and on virtual reality, as well as giving an overhaul of the standard material. Particular emphasis is given to the properties and calculation of reverberation, the most obvious acoustical feature of a room. And further key topics include the various mechanisms of sound absorption and their practical application as well as scattering by wall irregularities including pseudo-stochastic structures. Extensive space is given to of psychoacoustic insights and the quality criteria derived from them, along with new procedures for the sensory assessment of concert hall acoustics. As in earlier editions, one full and updated chapter is devoted to the design and performance of electroacoustic systems which nowadays is not just a method for sound amplification but offers many possibilities for correcting acoustic deficiencies and modifying a hall’s natural acoustics.

Architectural Acoustics offers a comprehensive overview of acoustical science at a level suitable for either advanced undergraduate or introductory graduate courses in architectural design and architectural engineering. The text is organized according to how sound interacts with built structures, going from simple geometries through complex building structures. The book begins with a brief but useful history of architecture and the role of acoustics, as well as overview of human perception of, sound, and then progresses through topics ranging from acoustic measurement, noise metrics and environmental noise, to sound in enclosed spaces, sound transmission in buildings, vibration and vibration isolation, and noise in mechanical systems. Architectural Acoustics also includes more advanced chapters on specific design problems, including treatment of multifamily dwellings, office buildings, sound reinforcement systems, rooms for music, multipurpose rooms, auditoriums, sanctuaries, and studios and listening rooms. Also covered is the theory loudspeaker systems and sound system modeling as well as in-depth presentation of computer modeling, ray tracing and auralization. * Comprehensive guide to the basics of acoustical science and its applications to architectural design. * Author is renowned expert engaged in acoustical engineering for 20 years * Covers the latest environmental regulations and health and safety research related to sound inside and outside of buildings.

Absorbers and diffusers are two of the main design tools for altering the acoustic conditions of rooms, semi-enclosed spaces and the outdoor environment. Their correct use is important for delivering high quality acoustics. Unique and authoritative, this book decribes how to effectively measure, model, design and apply diffusers and absorbers. It is a resource for new and experienced acousticians, seeking an understanding of the evolution, characteristics and application of modern diffusers. Absorption is a more established technology and so the book blends traditional designs with modern developments. The book covers practical and theoretical aspects of absorbers and diffusers and is well illustrated with examples of installations and case studies. This new edition brings Acoustic Absorbers and Diffusers up-to-date with current research, practice and standards. New developments in measurement, materials, theory and practice since the first edition (published in 2004) are included. The sections on absorbers are extended to include more about noise control.

The acoustics of a space can have a real impact on the sounds you create and capture. Acoustics and Psychoacoustics, Fifth Edition provides supportive tools and exercises to help you understand how music sounds and behaves in different spaces, whether during a performance or a recording, when planning a control room or listening space, and how it is perceived by performers, listeners, and recording engineers. With their clear and simple style, Howard and Angus cover both theory and practice by addressing the science of sound engineering and music production, the acoustics of musical instruments, the ways in which we hear musical sounds, the underlying principles of sound processing, and the application of these concepts to music spaces to create professional sound. This new edition is fully revised to reflect new psychoacoustic information related to timbre and temporal perception, including an updated discussion of vocal fold vibration principles, samples of recent acoustic treatments, and a description of variable acoustics in spaces, as well as coverage of the environment’s effect on production listening, sonification, and other topics. Devoted to the teaching of musical understanding, an accompanying website (www.routledge.com/cw/howard) features various audio clips, tutorial sheets, questions and answers, and trainings that will take your perception of sound to the next level. This book will help you: Gain a basic grounding in acoustics and psychoacoustics with respect to music audio technology systems Incorporate knowledge of psychoacoustics in future music technology system designs as appropriate Understand how we hear pitch, loudness, and timbre Learn to influence the acoustics of an enclosed space through designed physical modifications

A room’s acoustic character seems at once the most technical and the most mystical of concerns. Since the early Enlightenment, European architects have systematically endeavored to represent and control the propagation of sound in large interior spaces. Their work has been informed by the science of sound but has also been entangled with debates on style, visualization techniques, performance practices, and the expansion of the listening public. Echo’s Chambers explores how architectural experimentation from the seventeenth through the mid-twentieth centuries laid the groundwork for concepts of acoustic space that are widely embraced in contemporary culture. It focuses on the role of echo and reverberation in the architecture of Pierre Patte, Claude-Nicolas Ledoux, Carl Ferdinand Langhans, and Le Corbusier, as well as the influential acoustic ideas of Athanasius Kircher, Richard Wagner, and Marshall McLuhan. Drawing on interdisciplinary theories of media and auditory culture, Joseph L. Clarke reveals how architecture has impacted the ways we continue to listen to, talk about, and creatively manipulate sound in the physical environment.

Since publication of the first edition in 1973, this professional and scientific reference has become the standard work in the field, providing detailed analysis of the state of the art in room acoustics. It outlines the theory and practice of sound behaviour in enclosed spaces. Particular emphasis is given to the properties and calculation of reverberation, the most obvious acoustical feature of a closed room. Further key topics include the mechanisms of sound absorption and psychoacoustical factors, from which design parameters and figures of merit are derived. Two chapters are devoted to practical questions such as measurement techniques and the procedures of room acoustical design. The interaction between a room's acoustic properties and its electroacoustic systems is also considered, and refined systems for optimizing listening conditions in a room are presented. This edition includes a new list of symbols, and updated sections include the measurement of the impulse response including a discussion of distortions, sound propagation as a diffusive process and scattering by wall irregularities.
