Acoustical Materials by Pranab Saha Pdf

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.

Propagation of Sound in Porous Media by J.F. Allard Pdf

This book has grown out of the research activities of the author in the fields of sound propagation in porous media and modelling of acoustic materials. It is assumed that the reader has a background of advanced calculus, including an introduction to differential equations, complex variables and matrix algebra. A prior exposure to theory of elasticity would be advantageous. Chapters 1-3 deal with sound propagation of plane waves in solids and fluids, and the topics of acoustic impedance and reflection coefficient are given a large emphasis. The topic of flow resistivity is presented in Chapter 2. Chapter 4 deals with sound propagation in porous materials having cylindrical pores. The topics of effective density, and of tortuosity, are presented. The thermal exchanges between the frame and the fluid, and the behaviour of the bulk modulus of the fluid, are described in this simple context. Chapter 5 is concerned with sound propagation in other porous materials, and the recent notions of characteristic dimensions, which describe thermal exchanges and the viscous forces at high frequencies, are introduced. In Chapter 6, the case of porous media having an elastic frame is considered in the context of Biot theory, where new topics described in Chapter 5 have been included.

Acoustic Metamaterials by Richard V. Craster,Sébastien Guenneau Pdf

About the book: This book is the first comprehensive review on acoustic metamaterials; novel materials which can manipulate sound waves in surprising ways, which include collimation, focusing, cloaking, sonic screening and extraordinary transmission. It covers both experimental and theoretical aspects of acoustic and elastic waves propagating in structured composites, with a focus on effective properties associated with negative refraction, lensing and cloaking. Most related books in the field address electromagnetic metamaterials and focus on numerical methods, and little (or no) experimental section. Each chapter will be authored by an acknowledged expert, amongst the topics covered will be experimental results on non-destructive imaging, cloaking by surface water waves, flexural waves in thin plates. Applications in medical ultrasound imaging and modeling of metamaterials will be emphasized too. The book can serve as a reference for researchers who wish to build a solid foundation of wave propagation in this class of novel materials.

Architectural Acoustics Illustrated by Michael Ermann Pdf

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.

Acoustics and Sound Insulation by Eckard Mommertz Pdf

Schallschutz und Akustik gehören vielleicht nicht zu den primären Parametern, die den Entwurf eines Gebäudes normalerweise beeinflussen. Doch spätestens wenn man den Vortragenden im Seminarraum nicht versteht, der Geräuschpegel im Großraumbüro unerträgliche Ausmaße annimmt oder das Rumoren des Nachbars einem den Schlaf raubt, wird klar, wie wesentlich die Raumakustik zum alltäglichen Wohlbefinden beiträgt. Nicht nur Konzertsäle oder das antike Amphitheater erheben Anspruch auf akustische Qualität, sondern jedes Gebäude, sogar jeder Raum besitzt eine akustische Dimension, die je nach Funktion in ihren individuellen Anforderungen variiert. Der vorliegende Praxis-Band vermittelt allen Fachplanern, Architekten, aber auch interessierten Bauherren praxisnahe Kenntnisse zum Thema Akustik im Hochbau, angefangen von normativen Regelungen über Planungs- und Prognosemethoden bis hin zu den Bereichen Raumakustik, Bauakustik und Schallschutz im Städtebau. Typologische Kapitel erläutern beispielhaft den richtigen Umgang mit der Thematik an verschiedenen Gebäudearten wie beispielsweise Wohn- und Bürogebäuden, Schulen, Kindergärten, Hörsälen, Veranstaltungsräumen etc. , denn angemessene akustische Bedingungen tragen zum Erfolg eines Projektes massgeblich bei.
