This is a textbook on the basic sciences of sound. It contains sufficient latest information on the subject and is divided into four parts that fit into the semester structure.The first part deals with basic Newton's second law of motion, simple harmonic oscillation, and wave properties. Newton's second law, 'the net force is equal to the rate of change of momentum,' is used to derive the speed of waves in a medium. The second part focuses on the psychoacoustics of our perception of three attributes of sound: loudness, pitch and timbre. The third part discusses the basic physics of some musical instruments and human voice. From the point of view of physics, musical instruments and human speech are similar. They are composed of a sound source and a resonator. Human ingenuity has produced various aesthetic-looking and ear-pleasing instruments for musicians to perform. Magical human evolution has also shaped our vocal folds and vocal tract so that we can dynamically change loudness, pitch, and timbre in an instant, in a manner that no other musical instrument can emulate. The fourth part includes electricity and magnetism, room acoustics, digital technology in acoustics, effects of noise on human hearing, and noise regulations for hearing protection that are relevant to sound wave production, transmission, storage, and human ear protection. Our ears are extremely sensitive. Without proper protection, loud noise including loud music can damage our ears. Government regulation and education serve as a first line of protection in working environments.This small book is comprehensible, understandable and enjoyable to all eager students.

This book is about recent research in the area of profiling humans from their voice, which seeks to deduce and describe the speaker's entire persona and their surroundings from voice alone. It covers several key aspects of this technology, describing how the human voice is unique in its ability to both capture and influence the human persona -- how, in some ways, voice is more potent and valuable then DNA and fingerprints as a metric, since it not only carries information about the speaker, but also about their current state and their surroundings at the time of speaking. It provides a comprehensive review of advances made in multiple scientific fields that now contribute to its foundations. It describes how artificial intelligence enables mechanisms of discovery that were not possible before in this context, driving the field forward in unprecedented ways. It also touches upon related and relevant challenges posed by voice disguise and other mechanisms of voice manipulation. The book acts as a good resource for academic researchers, and for professional agencies in many areas such as law enforcement, healthcare, social services, entertainment etc.

This book highlights the mathematical and physical properties of acoustical sources with singularities located in the complex plane and presents the application of such special elements to solve acoustical radiation and scattering problems. Sources whose origin lies in the complex plane are also solutions of the wave equation but possess different radiating properties as their counterparts with real positions. Such mathematical constructions are known in the fields of optics and electrodynamics, but they are not common in acoustical research. The objective of the book is to introduce this concept to acousticians and motivate them to engage themselves in further research and application of complex sources. Such sources are particularly useful to formulate Green's functions and related equivalent source and boundary element methods in half-spaces.

This book provides an introduction to Acoustic Emission Testing and its applications to different materials like concrete, steel, ceramics, geotechnical materials, polymers, biological structures and wood. Acoustic Emission Techniques (AET) techniques have been studied in engineering for a long time. The techniques are applied more and more to practical investigations and are more and more standardized in codes. This is because the degradation of structures due to ageing urgently demand for maintenance and rehabilitation of structures in service. It results in the need for the development of advanced and efficient inspection techniques. In mechanical engineering and concerning the monitoring of machines and mechanical components, AE is a widely accepted observing deterioration in the frame of structural health monitoring. The advantages of AE like sensitivity, damage localization potential, non-intrusive nature as well as developments in signal analysis and data transmission allow applications that could not be considered decades ago. As such, AE techniques draw great attention to diagnostic applications and in material testing. This book covers all levels from the description of AE basics for AE beginners (level of a student) to sophisticated AE algorithms and applications to real large-scale structures as well as the observation of the cracking process in laboratory specimen to study fracture processes. This book has proved its worth over the past twelve years. Now in its second edition, it will be a resource that sets the standard and equips readers for the future. All chapters from the 1st edition have been updated and rewritten and eight extra chapters (e.g also regarding AE tomography, AE in plate-like structures and AE for investigations of hardening of fresh concrete) have been added.

The book describes analytical methods (based primarily on classical modal synthesis), the Finite Element Method (FEM), Boundary Element Method (BEM), Statistical Energy Analysis (SEA), Energy Finite Element Analysis (EFEA), Hybrid Methods (FEM-SEA and Transfer Path Analysis), and Wave-Based Methods. The book also includes procedures for designing noise and vibration control treatments, optimizing structures for reduced vibration and noise, and estimating the uncertainties in analysis results. Written by several well-known authors, each chapter includes theoretical formulations, along with practical applications to actual structural-acoustic systems. Readers will learn how to use vibroacoustic analysis methods in product design and development; how to perform transient, frequency (deterministic and random), and statistical vibroacoustic analyses; and how to choose appropriate structural and acoustic computational methods for their applications. The book can be used as a general reference for practicing engineers, or as a text for a technical short course or graduate course.

This book presents sixteen chapters in Volume 1. This Volume I of the Proceedings of the Worldwide Music Conference 2021 offers a smorgasbord of scientific approaches to music. The congress is one of a kind; it is dedicated not to a specific field but to the interdisciplinary developments and the interaction with the representatives from actual scientific disciplines. The languages of mathematics, computer science, semiotics, palaeography, and medicine are in the mix; geography of the studies is also impressive-Greece, Mexico, China, Russia, India, Poland, and USA, to name just a few. The purpose of such juxtaposition is to see how the terminology, categorical apparatus, and interpretations of music vary from science to science and how this can enrich the terminology of music theory. They cover a wide range of topics that the editors divided into four subfields: music in interdisciplinary contexts, music and current technology, musical instruments and voice, and music pedagogy and medicine. The opening section of the Proceedings is thus dedicated to the idea of interdisciplinarity, relationship of creator of theory of harmony Rameau to sciences of his time, the idea of number in music, co-creation, and the category of musical network. Three more chapters here deal with Russian palaeography, Indian musical genre, and the idea of musical semiotics. It is a kind of opening statement from music theorists. Part two, music and current technology, united three chapters, on "zero gravity" concept in modern music, discussion of scales as mathematical networks, and the innovation in digital music making, transforming it from stationary to mobile applications. The third part, musical instruments and voice, is of special interest because it is in the study of the instruments, the design, acoustic characteristics, and tuning, and sciences have cooperated with music theory for centuries. In addition to instruments, one chapter here is dedicated to voice. The last part, musical pedagogy and medicine, takes the reader even further into the interdisciplinary domain. The Proceedings is written in standard English language, prepared for the pleasure of reading of wide circles of professionals in different fields. The purpose of the editors is to bring this rather diverse set of texts into the context of a fruitful dialogue.
