Book Synopsis Engineering Acoustics by : Michael Möser
Download or read book Engineering Acoustics written by Michael Möser and published by Springer Science & Business Media. This book was released on 2009-09-01 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: Suitable for both individual and group learning, Engineering Acoustics focuses on basic concepts and methods to make our environments quieter, both in buildings and in the open air. The author’s tutorial style derives from the conviction that understanding is enhanced when the necessity behind the particular teaching approach is made clear. He also combines mathematical derivations and formulas with extensive explanations and examples to deepen comprehension. Fundamental chapters on the physics and perception of sound precede those on noise reduction (elastic isolation) methods. The last chapter deals with microphones and loudspeakers. Moeser includes major discoveries by Lothar Cremer, including the optimum impedance for mufflers and the coincidence effect behind structural acoustic transmission. The appendix gives a short introduction on the use of complex amplitudes in acoustics.

Available in PDF, EPUB and Kindle. Book excerpt: Whcn the original German edition of this book first appeared in print, the undcrsigned was asked to review it for an English-language journal. In the course of this review process he was so struck by the book's unusual approach, as well as by the realization that no similar collection of information was available in English, that he conceived thc idea of undertaking this translation. Arrangements with the original authors and with the publisher were completed late in 1969; the translation task was begun at that. time and occupied nearly two and onc-half years-largcly because the undersigned's other professional act.ivities permitted him toderote only hisspare time to the translation effort. Because this passage of time also brought with it some advances in the state of t.he art, an attempt was made to include the most significant of these aclvances, as well as newer references and some minor correc tions, in the translatecl rersion. Except for these changes, which were macle with the enthusiastic endorsement and collaboration of the origi nal authors, the translatecl rersion remains very close to the original. In fact, the translator took special care to preserve not only the mean ing, but also the "flaror", of the original text. The translator is most grateful to Professor L. Cremer and Dr

Book Synopsis Wave Propagation Approach for Structural Vibration by : Chongjian Wu
Download or read book Wave Propagation Approach for Structural Vibration written by Chongjian Wu and published by Springer Nature. This book was released on 2020-10-28 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended for researchers, graduate students and engineers in the fields of structure-borne sound, structural dynamics, and noise and vibration control. Based on vibration differential equations, it presents equations derived from the exponential function in the time domain, providing a unified framework for structural vibration analysis, which makes it more regular and normalized. This wave propagation approach (WPA) divides structures at “discontinuity points,” and the waves show characteristics of propagation, reflection, attenuation, and waveform conversion. In each segment of the system between two “discontinuity points,” the governing equation and constraint are expressed accurately, allowing the dynamic properties of complex systems to be precisely obtained. Starting with basic structures such as beams and plates, the book then discusses theoretical research on complicated and hybrid dynamical systems, and demonstrates that structural vibration can be analyzed from the perspective of elastic waves by applying WPA.
Download or read book Auralization written by Michael Vorländer and published by Springer Science & Business Media. This book was released on 2007-10-27 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Structure-borne Sound Sources in Buildings by : Matthias Lievens
Download or read book Structure-borne Sound Sources in Buildings written by Matthias Lievens and published by Logos Verlag Berlin GmbH. This book was released on 2013 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structure-borne sound sources are vibrational sources connected in some way to the building structure. The mechanical excitation of the building structure leads to sound radiation. This is an important source of annoyance in modern light-weight buildings. The prediction of the sound pressure level from structure-borne sound sources is highly complicated because of the complexity involved in the coupling between source and receiver structure. The current standard on characterisation of service equipment in buildings EN 12354-5, can deal with sources on heavy structures (high-mobility source) but to date, there is no engineering method available for the case of coupling between source and receiver. A case study of a washing machine on a wooden joist floor is investigated in this thesis. In the first part, measurements in the coupled state are conducted. It is shown that the normal components are sufficient to predict the sound pressure level. However, this only applies to the coupled state. In the second part, a true prediction is calculated from independently measured source and receiver quantities. The difference between predicted and directly measured sound pressure level leads to considerable errors of up to 20 dB at low frequencies. This shows that the normal components are not sufficient to predict the coupling between a washing machine and a wooden floor.
