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.

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.

Describing Music Materials by Richard P. Smiraglia Pdf

This fourth edition was prepared in 2015-2016 as a supplementary text for a graduate music cataloging course. This edition is rewritten to a large extent to conform to the new instructions and paradigms represented in Resource Description and Access (RDA). RDA instructions for printed music, recorded music and music video are accompanied by advice, examples, illustrations and complete catalog records, including versions in MARC21 format. Consistent with RDA, the chapter on form and choice of access points found in earlier editions is gone, replaced with a chapter on authorized access points. The concept of “uniform title” has evolved into the concept of the “preferred title,” as part of an authorized access point, which might require manipulation and addition of some elements for disambiguation and collocation. Only three chapters are used for description of printed music, sound recordings and video recordings. Many of the older LP examples were removed as were VHS video recordings. Multimedia packages are now rare in the marketplace, but streaming audio and video are quite evident so examples now include those media. Facsimile examples from the third edition have been retained and many new examples have been added. Most catalogers today are using RDA in combination with MARC21. Accordingly, in an appendix, we have rendered each example in MARC21 format using the OCLC Connexion approach to MARC21 record formatting.A lengthy bibliography in earlier editions has been replaced by a brief list in the introduction, with pointers to online resources that are both current and constantly updated by working catalogers.

Site Control of Materials by John E Johnston Pdf

Site Control of Materials: Handling, Storage and Protection deals with improving control in construction sites to limit waste resulting from improper storage and handling of valuable or fragile materials. According to the Building Research Establishment in the United Kingdom, 10-20% of all materials delivered to the construction site either end up as waste or are illegally removed during the contract. Bigger construction contracts such as in housing developments require new kinds of materials in larger volumes and new construction techniques, leading to increases in waste. To be able to lessen wastage, site management must 1) anticipate the progress and problems of construction; 2) control men and materials with equal efficiency; 3) complete the contract within the programmed period; and 4) carry out the work according to specification. The book explains in detail the procedures for obtaining materials, materials handing (including unit loads, pallets, deliveries, offloading), storage (stockpile arrangements, protection, facilities, withdrawals), as well as implementing stock controls on sites (coordination, transfer, accounting). The text also addresses prevention of on-site damages through site supervision, out-of-hours supervision, and installing fire precautions. The book should prove valuable for construction engineers, foremen, project managers, plant administrators, warehouse keepers, and other personnel connected with materials handling, their storage or safekeeping.

Designing Sound by Andy Farnell Pdf

A practitioner's guide to the basic principles of creating sound effects using easily accessed free software. Designing Sound teaches students and professional sound designers to understand and create sound effects starting from nothing. Its thesis is that any sound can be generated from first principles, guided by analysis and synthesis. The text takes a practitioner's perspective, exploring the basic principles of making ordinary, everyday sounds using an easily accessed free software. Readers use the Pure Data (Pd) language to construct sound objects, which are more flexible and useful than recordings. Sound is considered as a process, rather than as data—an approach sometimes known as “procedural audio.” Procedural sound is a living sound effect that can run as computer code and be changed in real time according to unpredictable events. Applications include video games, film, animation, and media in which sound is part of an interactive process. The book takes a practical, systematic approach to the subject, teaching by example and providing background information that offers a firm theoretical context for its pragmatic stance. [Many of the examples follow a pattern, beginning with a discussion of the nature and physics of a sound, proceeding through the development of models and the implementation of examples, to the final step of producing a Pure Data program for the desired sound. Different synthesis methods are discussed, analyzed, and refined throughout.] After mastering the techniques presented in Designing Sound, students will be able to build their own sound objects for use in interactive applications and other projects
