Free Download Noise Pollution and Ergonomic Intervention by Acoustic Material
English | 2025 | ISBN: 3031663071 | 90 Pages | PDF (True) | 3.4 MB
This book is based on the understanding as well as the use of information technology extensively, to explore OHS related risk in major risky sectors due to noise and a framework is suggested through the systematic analysis of the barriers and its implementations. Ergonomic analysis is done to investigate problems associated with hearing. Acoustic materials are fabricated and tested. A case study is conducted to reduce noise by placing accoustic material.

Free Download Multilayer Integrated Film Bulk Acoustic Resonators By Yafei Zhang, Da Chen (auth.)
2013 | 154 Pages | ISBN: 3642317758 | PDF | 4 MB
Mulilayer Integrated Film Bulk Acoustic Resonators mainly introduces the theory, design, fabrication technology and application of a recently developed new type of device, multilayer integrated film bulk acoustic resonators, at the micro and nano scale involving microelectronic devices, integrated circuits, optical devices, sensors and actuators, acoustic resonators, micro-nano manufacturing, multilayer integration, device theory and design principles, etc. These devices can work at very high frequencies by using the newly developed theory, design, and fabrication technology of nano and micro devices. Readers in fields of IC, electronic devices, sensors, materials, and films etc. will benefit from this book by learning the detailed fundamentals and potential applications of these advanced devices. Prof. Yafei Zhang is the director of the Ministry of Education’s Key Laboratory for Thin Films and Microfabrication Technology, PRC; Dr. Da Chen was a PhD student in Prof. Yafei Zhang’s research group.

Free Download Distributed Acoustic Sensing in Borehole Geophysics
English | 2025 | ISBN: 1394179243 | 615 Pages | PDF, EPUB (True) | 330 MB
Borehole geophysics involves measuring, imaging, and monitoring subsurface structures and activities by putting instruments into wellbores. Distributed acoustic sensing (DAS) technology is emerging as an effective and reliable tool in borehole geophysics because fiber-optic cables deployed at depth can produce high-quality data and images, even in harsh high-temperature and high-pressure environments.

Free Download Justin K. Burnett, "Theory and Uses of Acoustic Emissions "
English | ISBN: 1612099602 | 2012 | 289 pages | PDF | 12 MB
Acoustic Emission (AE) is a naturally occurring phenomenon whereby external stimuli, such as mechanical loading, generate sources of elastic waves. AE occurs when a small surface displacement of a material is produced due to stress waves generated when there is a rapid release of energy in a material, or on its surface. This new book presents current research in the study of the theory and uses of acoustic emissions. Topics discussed include acoustic emission from rocks generated in the course of a variety of experiments; applying the acoustic emission technique to estimate the defect density and strength of adhesively bonded couplings and structural health monitoring of ships and offshore structures using acoustic emission testing.

Free Download Surface Acoustic Waves in Inhomogeneous Media By Dr. Sergey V. Biryukov, Prof. Yuri V. Gulyaev, Prof. Victor V. Krylov, Dr. Victor P. Plessky (auth.)
1995 | 389 Pages | ISBN: 364263348X | PDF | 27 MB
Surface Acoustic Waves in Inhomogeneous Media covers almost all important problems of the interaction of different types of surface acoustic waves with surface inhomogeneities. The problems of surface acoustic wave interaction with periodic topographic gratings widely used in filters and resonators are under careful consideration. The most important results of surface wave scattering by local defects such as grooves, random roughness, elastic wedges are given. Different theoretical approaches and practical rules for solving the surface wave problems are presented.

Free Download Fundamentals of Acoustic Waves and Applications (Synthesis Lectures on Wave Phenomena in the Physical Sciences) by Sanichiro Yoshida
English | March 2, 2024 | ISBN: 3031481992 | 180 pages | MOBI | 26 Mb
This book discusses acoustic waves in five chapters. Chapter 1 reviews the general properties of waves. Chapter 2 presents the acoustic waves in fluid and solids, including the wave equations in the respective media. Chapter 3 discusses the propagation of audible acoustic waves in the air. The discussion includes analyses of speech and music we hear in the time and frequency domains. Chapter 4 discusses the propagation of acoustic waves in solids. Unlike in the air, sound waves take complicated forms in solids; they can be both in longitudinal and transverse modes, and mode conversions can occur upon reflection. Although these behaviors make the analysis difficult, we can apply them to engineering problems. Chapter 5 describes the transduction of acoustic signals. It presents acoustic transmitters and sensors along with their operation principles. Finally, Chapter 6 presents several techniques used in engineering. It is also useful to consider applying acoustic and optical techniques to engineering problems.
