The Journal Of The Acoustical Society Of America

This corrected version of the landmark 1981 textbook introduces the physical principles and theoretical basis of acoustics with deep mathematical rigor, concentrating on concepts and points of view that have proven useful in applications such as noise control, underwater sound, architectural acoustics, audio engineering, nondestructive testing, remote sensing, and medical ultrasonics. Since its publication, this text has been used as part of numerous acoustics-related courses across the world, and continues to be used widely today. During its writing, the book was fine-tuned according to insights gleaned from a broad range of classroom settings. Its careful design supports students in their pursuit of a firm foundation while allowing flexibility in course structure. The book can easily be used in single-term or full-year graduate courses and includes problems and answers. This rigorous and essential text is a must-have for any practicing or aspiring acoustician.

Unite the science of sound and the principles of design toenhance any space Architectural Acoustics Illustrated translates thequantitative and qualitative content of acoustics into the graphiclanguage of architecture. This highly-visual guide includes over350 illustrations that outline the physics of sound and the bestdesign practices for limiting or mitigating noise in buildings byusing the latest in materials and techniques. Each chapter includesa summary checklist of design guidelines to help prevent mistakesand oversights, and the Instructor's website offers videoanimations demonstrating acoustical concepts. Designed as a "firstlook" at the interaction of sound and space, the book explains theprinciples of architectural acoustics and their practicalapplications, providing a comprehensive guide for designing withacoustics in mind. Architectural acoustics is more than just concert halls –it may determine building placement, division of interior space,exterior construction, and even siting. When addressed early in thedesign process, the resulting space can be free of unwanted soundand promote good hearing; if left unaddressed, the problems withthe space can lead to lawsuits and costly post-constructionremediation. Architectural Acoustics Illustrated helpsdesigners solve most acoustical problems in advance, by enablingreaders to: Understand the physical science underlying the behavior ofsound Consider the interactions of sound and space in the initialdesign approach Mitigate building sounds such as those produced by HVAC andplumbing with early design planning Design spaces for listening, and incorporate acoustics bestpractices into every plan The highly visual format of the book helps readers grasp complexconcepts quickly, and thorough discussion of each concept'sreal-world application ties the science directly into the designprocess. All design professionals need to have a fundamentalunderstanding of acoustics, and Architectural AcousticsIllustrated is a comprehensive, practical guide in aneasy-to-read format.

What is acoustics? What is noise? How is sound measured? How can the vehicle noise be reduced using sound package treatments? Pranab Saha answers these and more in Acoustical Materials. Acoustics is the science of sound, including its generation, propagation, and effect. Although the propulsion sources of internal combustion engine (ICE) vehicles and electric motor-powered vehicles (EV) are different and therefore their propulsion noises are different, both types of vehicles have shared noise concerns: Tire and road noise Wind noise Vehicle noise and vibration issues have been there almost from the inception of vehicle manufacturing. The noise problem in a vehicle is very severe and is difficult to solve only by modifying the sources of noise and vibration. Sound package treatments address the noise and vibration issues along the path to reduce in-cabin noise. In Acoustical Materials, readers will grasp the science of reducing sound and vibration using sound absorbers, sound barriers, and vibration dampers. Sound provides information on the proper operation of the vehicle, but if unchecked, can detract from the consumer experience within the vehicle and create noise pollution outside the vehicle. Acoustical Materials provides essential information on the basics of sound, vehicle noise source, how these are measured, how vehicle owners perceive sound, and ultimately, how to solve noise problems in vehicles using sound package materials.

This is the first focused and detailed textbook on acoustic virtual reality. Auralization is the creation of audible acoustic sceneries from computer-generated data. The term "auralization" is to be understood as being analogue to the well-known technique of "visualization". In visual illustration of scenes, data or any other meaningful information, in movie animation and in computer graphics, we describe the process of "making visible" as visualization. In acoustics, auralization is taking place when acoustic effects, primary sound signals or means of sound reinforcement or sound transmission, are processed to be presented by using electro-acoustic equipment. This book is organized as a comprehensive collection of basics, methodology and strategies of acoustic simulation and auralization.
