Book Description
Though noise reduction and speech enhancement problems have been studied for at least five decades, advances in our understanding and the development of reliable algorithms are more important than ever, as they support the design of tailored solutions for clearly defined applications. In this work, the authors propose a conceptual framework that can be applied to the many different aspects of noise reduction, offering a uniform approach to monaural and binaural noise reduction problems, in the time domain and in the frequency domain, and involving a single or multiple microphones. Moreover, the derivation of optimal filters is simplified, as are the performance measures used for their evaluation.

Book Description
Noise is everywhere and in most applications that are related to audio and speech, such as human-machine interfaces, hands-free communications, voice over IP (VoIP), hearing aids, teleconferencing/telepresence/telecollaboration systems, and so many others, the signal of interest (usually speech) that is picked up by a microphone is generally contaminated by noise. As a result, the microphone signal has to be cleaned up with digital signal processing tools before it is stored, analyzed, transmitted, or played out. This cleaning process is often called noise reduction and this topic has attracted a considerable amount of research and engineering attention for several decades. One of the objectives of this book is to present in a common framework an overview of the state of the art of noise reduction algorithms in the single-channel (one microphone) case. The focus is on the most useful approaches, i.e., filtering techniques (in different domains) and spectral enhancement methods. The other objective of Noise Reduction in Speech Processing is to derive all these well-known techniques in a rigorous way and prove many fundamental and intuitive results often taken for granted. This book is especially written for graduate students and research engineers who work on noise reduction for speech and audio applications and want to understand the subtle mechanisms behind each approach. Many new and interesting concepts are presented in this text that we hope the readers will find useful and inspiring.

Book Description
Additive noise is ubiquitous in acoustics environments and can affect the intelligibility and quality of speech signals. Therefore, a so-called noise reduction algorithm is required to mitigate the effect of the noise that is picked up by the microphones. This work proposes a general framework in the time domain for the single and multiple microphone cases, from which it is very convenient to derive, study, and analyze all kind of optimal noise reduction filters. Not only that all known algorithms can be deduced from this approach, shedding more light on how they function, but new ones can be discovered as well.

Book Description
A young man begins a journey from Saudi Arabia, believing it will end with his death in England. If his mission succeeds, he will go to his god a martyr - and many innocents will die with him. For David Banks, an armed protection officer, charged with neutralizing the threat to London's safety, his role is no longer clear-cut: one man's terrorist is another man's freedom fighter: dangerous distinctions to a police officer with his finger on the trigger. Soon the two men's paths will cross. Before then, their commitment will be shaken by the journeys that take them there. The suicide bomber and the policeman will have cause to question the roads they've chosen. Win or lose, neither will be the same again...

Book Description
Over the past two decades there have been many major new developments in the field of urban sound environment. Jian Kang introduces and examines these key developments, including: the development of prediction methods for urban sound propagation establishment and application of noise-mapping software new noise control measures and design methods. Also covered is the new EU directive on noise and the substantial actions it has brought about across Europe. As the importance of soundscape, acoustic comfort and sound environment design have become widely recognized, Urban Sound Environments is a thoroughly useful book for students and practitioners in a wide range of fields, from urban planning and landscape through to architecture and acoustics.

Book Description
From the very beginnings of sound recording, engineers have strived to reproduce the original sound as purely as possible and overcome the noise that technology leaves in recordings. However, this desire denies the fact that technologically mediated sound is always shaped and filtered by themany channels it travels through as it is recorded and reproduced. The noise that each medium inscribes on recorded sound is not just inescapable - it is fundamental to the sonic contours that characterize recorded music. But how exactly do media technologies shape sound and music? And how have theychanged what we listen for in music over time?In The Logic of Filtering, author Melle Jan Kromhout develops an extensive media archaeological analysis of the 'noise of sound media' that covers all the disturbances, distortions, and interferences that media add to the sounds they reproduce. Combining theoretical, historical, and technicalperspectives on sound media, Kromhout sketches a broad history of the problem of noise in sound recording as he traces the ideal of sonic purity back to nineteenth-century acoustics, examines analog and digital technologies, and analyzes the relationship between noise and temporality. In thoroughlyrevising our understanding of how sound media impact the sonorous qualities of music, this book offers a fresh perspective on the interactions between music, media, and listeners.
