Описание: The book explores new ways to reconstruct and enhance speech that is compromised by various neuro-motor disorders – collectively known as “dysarthria.” The authors address some of the extant lacunae in speech research of dysarthric conditions: they show how new methods can improve speaker recognition when speech is impaired due to developmental or acquired pathologies; they present a novel multi-dimensional approach to help the speech system both assess dysarthric speech and to perform intelligibility improvement of the impaired speech; they display well-performing software solutions for developmental and acquired speech impairments, and for vocal injuries; and they examine non-acoustic signals and muted nonverbal sounds in relation to audible speech conversion.

Описание: The Fundamentals of Sound Science teaches the principles of the physics of sound, as well as basic principles of physics, by linking them to music and musical instruments.The book begins by asking students to question the meaning of sound itself. What is sound? How far and how fast does it travel? By asking students to think about sound in this way, the material is able to connect our daily experience of sound to principles of physics such as distance, velocity, scalars, and vectors. Through the next six chapters students learn about harmonic motion, waves, the sources and physical properties of sound, and measurements of loudness.The second half of the book uses music as the vehicle for a deeper exploration of sound. Students study some basic musicianship, including articulation, intervals, and harmonic series. These concepts become the springboard for an examination of the Fourier Analysis of Simplest Sound Spectra, which encompasses steady tones, periodic waves of arbitrary form, square, triangular, and sawtooth waves, and modulated tones.Different families of instruments are discussed in depth: percussion, strings, flutes and recorders, woodwinds, and finally the human voice. The book concludes with a chapter on room acoustics, which covers the precedence effect and reverberations.Each chapter is filled with detailed explanations, and numerous examples are used to enhance student understanding. Study questions are included to encourage critical thinking, and prepare students for tests. Chapter summaries aid retention by reviewing terms and relations.By finding the common ground between physics and music, The Fundamentals of Sound Science strengthens understanding of both, revealing that many principles of the physical world are a part of our common, taken for granted, daily experience. All we have to do is listen.The Fundamentals of Sound Science can be used for introductory courses in physics, including those at the high school level. The accessibility of the material makes the book appropriate for non-majors at the university level, and students can achieve mastery of the content without a background in mathematics, making the book ideal for general education courses.

Описание: This book provides a comprehensive introduction to the theory and practice of spherical microphone arrays, and was written for graduate students, researchers and engineers who work with spherical microphone arrays in a wide range of applications. The new edition includes additions and modifications, and references supplementary Matlab code to provide the reader with a straightforward start for own implementations. The book is also accompanied by a Matlab manual, which explains how to implement the examples and simulations presented in the book.The first two chapters provide the reader with the necessary mathematical and physical background, including an introduction to the spherical Fourier transform and the formulation of plane-wave sound fields in the spherical harmonic domain. In turn, the third chapter covers the theory of spatial sampling, employed when selecting the positions of microphones to sample sound pressure functions in space. Subsequent chapters highlight various spherical array configurations, including the popular rigid-sphere-based configuration. Beamforming (spatial filtering) in the spherical harmonics domain, including axis-symmetric beamforming, and the performance measures of directivity index and white noise gain are introduced, and a range of optimal beamformers for spherical arrays, including those that achieve maximum directivity and maximum robustness are developed, along with the Dolph–Chebyshev beamformer. The final chapter discusses more advanced beamformers, such as MVDR (minimum variance distortionless response) and LCMV (linearly constrained minimum variance) types, which are tailored to the measured sound field.Mathworks kindly distributes the Matlab sources for this book on https://www.mathworks.com/matlabcentral/fileexchange/68655-fundamentals-of-spherical-array-processing.

Описание: This book highlights technology trends and challenges that trace the evolution of antenna design, starting from 3rd generation phones and moving towards the latest release of LTE-A. The authors explore how the simple monopole and whip antenna from the GSM years have evolved towards what we have today, an antenna design that is compact, multi-band in nature and caters to multiple elements on the same patch to provide high throughput connectivity. The scope of the book targets a broad range of subjects, including the microstrip antenna, PIFA antenna, and the monopole antenna to be used for different applications over three different mobile generations. Beyond that, the authors take a step into the future and look at antenna requirements for 5G communications, which already has the 5G drive in place with prominent scenarios and use-cases emerging. They examine these, and put in place the challenges that lie ahead for antenna design, particularly in mm-Wave design. The book provides a reference for practicing engineers and under/post graduate students working in this field.
