Acoustic Guitar Design

by Richard Mark French

This book is for experienced luthiers and guitar designers in the industry, novice builders wishing to improve their designs, and guitar owners interested in knowing more about their instruments. It includes the most important technical information gathered from many sources, including the academic literature and the author’s own work, presented here in a clear, actionable form with a minimum of mathematics. The book begins with a historical survey on how important features of the acoustic guitar evolved over centuries. The review leads up to a chapter focusing on three iconic instruments that represent the most important types of acoustic guitars: classical, steel string flat top and archtop. As the guitar market is so strongly conditioned by familiar, traditional instruments, a successful builder must have a thorough working understanding of the most important designs to underpin their own work. Through this volume, Professor French lays out the entire design process and collects detailed information in one convenient source. Luthiers quite often compile notebooks of measurements, part numbers, specific design features and other details they routinely need. This book organizes much of that information, with tables of dimensions, material properties, and other details in one essential final chapter. The book also features concise side bar contributions by top guitar designers and builders including Tim Shaw, Chief Engineer at Fender Music; Bob Taylor, Co-Founder of Taylor Guitars; and Andy Powers, Master Guitar Designer and Partner.

Acoustic Invisibility for Elliptic Objects: Theory and Experiments for Underwater Sound (SpringerBriefs in Applied Sciences and Technology)

by Davide Enrico Quadrelli Francesco Braghin

The book investigates acoustic cloaking for elliptical targets, starting from the development of a systematic approach to deal with such non-axisymmetrical shapes by adopting transformation acoustics in elliptic coordinates, and concluding with numerical and experimental validation of a microstructured cloak in the underwater environment. The book thus comprises all the steps from theory to practice that led to the first experimental validation of acoustic invisibility for non-cylindrical objects, whose results are presented in the last chapter. Indeed, despite Transformation Theory is now an established tool to design material distributions capable to unlock the design of invisibility devices, it is not trivial to apply it for shapes different than the sphere and the cylinder, which are thus the ones mainly addressed in the literature. This book paves the way for exploration of other shapes, demonstrating the effectiveness of a pentamode cloak in reducing the acoustic visibility of an elliptical target, and discussing design choices that can make the implementation of the required microstructure less cumbersome despite the lack of axial symmetry of the problem, from both the numerical and manufacturing point of views.

Acoustic Levitation: From Physics to Applications

by Duyang Zang

This book systematically introduces readers to the fundamental physics and a broad range of applications of acoustic levitation, one of the most promising techniques for the container-free handling of small solid particles and liquid droplets. As it does away with the need for solid walls and can easily be incorporated into analysis instruments, acoustic levitation has attracted considerable research interest in many fields, from fluid physics to material science. The book offers a comprehensive overview of acoustic levitation, including the history of acoustic radiation force; the design and development of acoustic levitators; the technology’s applications, ranging from drop dynamics studies to bio/chemical analysis; and the insightful perspectives that the technique provides. It also discusses the latest advances in the field, from experiments to numerical simulations. As such, the book provides readers with a clearer understanding of acoustic levitation, while also stimulating new research areas for scientists and engineers in physics, chemistry, biology, medicine and other related fields.

Acoustic Levitation-Based Trace-Level Biosensing: Design of Detection Systems and Applications to Real Samples (Springer Theses)

by Akihisa Miyagawa

This book shows the availability and potential of the coupled acoustic-gravitational (CAG) field for trace-level biosensing. The proposed detection scheme also allows the evaluation of the kinetics and thermodynamics of the reaction occurring on a single microparticle (MP). This method has wide applicability in important fields, involving not only chemistry but also life, environmental, and medical sciences. The author proposes novel trace-level biosensing based on measurements of the levitation coordinate shift of an MP in the CAG field. The levitation coordinate of the MP in the CAG field is determined by its density and compressibility. The levitation coordinate shift is induced by the binding of gold nanoparticles (AuNPs) to the MP through interparticle reactions. Therefore, the quantity of molecules involved in the reaction can be determined from the levitation coordinate shift. The author demonstrates the zmol level detection for biotin, DNA/RNA, and organic molecules. In addition, the kinetics and thermodynamics are evaluated for various reactions occurring between the MP and AuNP, such as the avidin-biotin reaction, direct hybridization, sandwich hybridization, and aptamer-target complexation.This book provides a new concept based on the CAG field, in which the extent of a reaction is converted into the levitation coordinate shift, that is, “length.” The proposed method has many advantages over other methods, e.g., high biocompatibility, high applicability, and short analysis time. In addition, because the apparatus used in this study is inexpensive and easy to miniaturize, this method is useful in important practical fields, such as forensic and environmental science and diagnosis. Thus, this book inspires many researchers to apply the present method to their own fields of interest.

Acoustic Waves in Periodic Structures, Metamaterials, and Porous Media: From Fundamentals to Industrial Applications (Topics in Applied Physics #143)

by Noé Jiménez Olga Umnova Jean-Philippe Groby

This book delivers a comprehensive and up-to-date treatment of practical applications of metamaterials, structured media, and conventional porous materials. With increasing levels of urbanization, a growing demand for motorized transport, and inefficient urban planning, environmental noise exposure is rapidly becoming a pressing societal and health concern. Phononic and sonic crystals, acoustic metamaterials, and metasurfaces can revolutionize noise and vibration control and, in many cases, replace traditional porous materials for these applications.In this collection of contributed chapters, a group of international researchers reviews the essentials of acoustic wave propagation in metamaterials and porous absorbers with viscothermal losses, as well as the most recent advances in the design of acoustic metamaterial absorbers. The book features a detailed theoretical introduction describing commonly used modelling techniques such as plane wave expansion, multiple scattering theory, and the transfer matrix method. The following chapters give a detailed consideration of acoustic wave propagation in viscothermal fluids and porous media, and the extension of this theory to non-local models for fluid saturated metamaterials, along with a description of the relevant numerical methods. Finally, the book reviews a range of practical industrial applications, making it especially attractive as a white book targeted at the building, automotive, and aeronautic industries.

Acoustical Analysis of the Tanpura: Indian Plucked String Instrument (Signals and Communication Technology)

by Asoke Kumar Datta Ranjan Sengupta Kaushik Banerjee Dipak Ghosh

This book addresses the acoustic signal analysis and spectral dynamics of the tanpura, an Indian plucked string instrument. In addition, it strives to provide a logical and objective explanation of Indian classical musicians’ cognitive experience. Issues of relevance in this regard include the rich, mellifluous sound; the undulation of the loudness; the somewhat cyclical variation of the timbre, which is strongly related to these undulations; and the occasional perception of virtual notes to which no strings are tuned. The book analyses the materials used in the tanpura, the instrument’s simple structure, the intricacies of the lower bridge, and the theory of string vibration with variable string length. Cognitive experiments to provide the basis for perceptual quality assessment, as well as a methodology for ranking, are described. This is followed by acoustic analyses, both temporal and spectral, for sounds produced by male and female tanpuras, for each individual string and the combined one. An important aspect related to the naturalness of perceived sound, namely the intrinsically associated random perturbations, is also discussed. The apparent irregularities perceived in the acoustic signal produced by the tanpura reveal the importance of examining the signal from the perspective of non-linear analysis, an aspect that is also covered in the book. Given its scope, the book will appeal to students and researchers in the fields of music acoustics, artificial intelligence, and cognitive science, as well as musicians and musicologists around the world.

Acoustics and Aerodynamic Sound

by Michael Howe

Music, calm speech, whispering leaves fluttering in a breeze are pleasant and desirable sounds. Noise, howling gales, explosions and screeching traffic are less so. A quantitative understanding of the sources of all such sounds can be obtained by careful analysis of the mechanical equations of motion. This is provided by Acoustics and Aerodynamic Sound, which serves as a short, one semester introduction to acoustics and aerodynamic sound at the advanced undergraduate and graduate level. Sound is treated as a branch of fluid mechanics, which is possible because students embarking on an advanced course in acoustics will be familiar with this topic. It is also desirable because an ability to relate acoustic events to hydrodynamic phenomena provides insight into acoustic principles, in particular into the role of vorticity in the mechanics of sound production by vibrating bodies and in the scattering and diffraction of sound.

Acoustics, Information, and Communication: Memorial Volume in Honor of Manfred R. Schroeder (Modern Acoustics and Signal Processing)

by Ning Xiang Gerhard M. Sessler

This book explores the life and scientific legacy of Manfred Schroeder through personal reflections, scientific essays and Schroeder's own memoirs. Reflecting the wide range of Schroeder's activities, the first part of the book contains thirteen articles written by his colleagues and former students. Topics discussed include his early, pioneering contributions to the understanding of statistical room acoustics and to the measurement of reverberation time; his introduction of digital signal processing methods into acoustics; his use of ray tracing methods to study sound decay in rooms and his achievements in echo and feedback suppression and in noise reduction. Other chapters cover his seminal research in speech processing including the use of predictive coding to reduce audio bandwidth which led to various code-excited linear prediction schemes, today used extensively for speech coding. Several chapters discuss Schroeder's work in low-peak factor signals, number theory, and maximum-length sequences with key applications in hearing research, diffraction gratings, artificial reverberators and de-correlation techniques for enhancing subjective envelopment in surround sound. In style, the articles range from truly scientific to conversationally personal.

The second part of the book consists of Schroeder's own memoirs, written over the final decade of his life. These recollections shed light on many aspects not only of Schroeder's life but also on that of many of his colleagues, friends and contemporaries. They portray political, social and scientific events over a period that extends from pre-war to the present. These memoirs, written in an inimitable and witty style, are full of information, entertaining and fun to read, providing key insight into the life and work of one of the greatest acousticians of the 20th century.

Acoustics of Bangla Speech Sounds (Signals and Communication Technology)

by Asoke Kumar Datta

This book presents the consolidated acoustic data for all phones in Standard Colloquial Bengali (SCB), commonly known as Bangla, a Bengali language used by 350 million people in India, Bangladesh, and the Bengali diaspora. The book analyzes the real speech of selected native speakers of the Bangla dialect to ensure that a proper acoustical database is available for the development of speech technologies. The acoustic data presented consists of averages and their normal spread, represented by the standard deviations of necessary acoustic parameters including e. g. formant information for multiple native speakers of both sexes. The study employs two important speech technologies:(1) text to speech synthesis (TTS) and (2) automatic speech recognition (ASR). The procedures, particularly those related to the use of technologies, are described in sufficient detail to enable researchers to use them to create technical acoustic databases for any other Indian dialect. The book offers a unique resource for scientists and industrial practitioners who are interested in the acoustic analysis and processing of Indian dialects to develop similar dialect databases of their own.
