Since the publication of the first edition, considerable progress has been made in the development and application of active noise control (ANC) systems, particularly in the propeller aircraft and automotive industries. Treating the active control of both sound and vibration in a unified way, this second edition of Active Control of Noise and Vibration continues to combine coverage of fundamental principles with the most recent theoretical and practical developments. What’s New in This Edition Revised, expanded, and updated information in every chapter Advances in feedforward control algorithms, DSP hardware, and applications Practical application examples of active control of noise propagating in ducts The use of a sound intensity cost function, model reference control, sensing radiation modes, modal filtering, and a comparison of the effectiveness of various sensing strategies New material on feedback control of sound transmission into enclosed spaces New material on model uncertainty, experimental determination of the system model, optimization of the truncated model, collocated actuators and sensors, biologically inspired control, and a discussion of centralised versus de-centralised control A completely revised chapter on control system implementation New material on parametric array loudspeakers, turbulence filtering, and virtual sensing More material on smart structures, electrorheological fluids, and magnetorheological fluids Integrating the related disciplines of active noise control and active vibration control, this comprehensive two-volume set explains how to design and implement successful active control systems in practice.
Building or architectural acoustics is taken in this book to cover all aspects of sound and vibration in buildings. The book covers room acoustics but the main emphasis is on sound insulation and sound absorption and the basic aspects of noise and vibration problems connected to service equipment and external sources. Measuring techniques connected to these fields are also brought in. It is designed for advanced level engineering studies and is also valuable as a guide for practitioners and acoustic consultants who need to fulfil the demands of building regulations.I
This book provides an up-to-date presentation of a broad range of contemporary problems in inverse scattering involving acoustic, elastic and electromagnetic waves.
A delightful journey through the psychology and science of music, WHY YOU LOVE MUSIC is the perfect book for anyone who loves a tune.
Music plays a hugely important role in our emotional, intellectual, and even physical lives. It impacts the ways we work, relax, behave, and feel. It can make us smile or cry, it helps us bond with the people around us, and it even has the power to alleviate a range of medical conditions. The songs you love (and hate, and even the ones you feel pretty neutral about) don’t just make up the soundtrack to your life–they actually help to shape it.
In WHY YOU LOVE MUSIC, scientist and musician John Powell dives deep into decades of psychological and sociological studies in order to answer the question “Why does music affect us so profoundly?” With his relaxed, conversational style, Powell explores all aspects of music psychology, from how music helps babies bond with their mothers to the ways in which music can change the taste of wine or persuade you to spend more in restaurants. WHY YOU LOVE MUSIC will open your eyes (and ears) to the astounding variety of ways that music impacts the human experience.
For intermediate programmers, beginning sound designers.
Sound gives your native, web, or mobile apps that extra dimension, and it’s essential for games. Rather than using canned samples from a sample library, learn how to build sounds from the ground up and produce them for web projects using the Pure Data programming language. Even better, you’ll be able to integrate dynamic sound environments into your native apps or games–sound that reacts to the app, instead of sounding the same every time.
From the basics of using camera, handheld, lavalier, and shotgun microphones to camera calibration and mixer set-ups, Location Audio Simplified unlocks the secrets to clean and clear broadcast quality audio no matter what challenges you face. Author Dean Miles applies his twenty-plus years of experience as a professional location operator to teach the skills, techniques, tips, and secrets needed to produce high-quality production sound on location. Humorous and thoroughly practical, the book covers a wide array of topics, such as:* location selection* field mixing* booming techniques* using different kinds of microphones (including wireless systems) and booming* camera calibration, interview techniques, and much moreLearn the secrets of a real-world professional with easy-to-follow, non-technical tips and techniques that you can apply in the field on your own projects immediately.
Learn to use inexpensive and readily available parts to obtain state-of-the-art performance in all the vital parameters of noise, distortion, crosstalk and so on. With ample coverage of preamplifiers and mixers and a new chapter on headphone amplifiers, this practical handbook provides an extensive repertoire of circuits that can be put together to make almost any type of audio system.A resource packed full of valuable information, with virtually every page revealing nuggets of specialized knowledge not found elsewhere.
Trees can reduce noise by sound reflection and absorption and this is the first book bringing together the widely scattered literature on noise abatement by urban trees. The book will interest those concerned with environmental management, noise control, and urban forestry. It is an invaluable source of information for environmental managers, foresters, acousticians, engineers, architects, scientists, and students.
Materials development has reached a point where it is difficult for a single material to satisfy the needs of sophisticated applications in the modern world. Nanocomposite films and coatings achieve much more than the simple addition of the constitutents – the law of summation fails to work in the nano-world. This book encompasses three major parts of the development of nanocomposite films and coatings: the first focuses on processing and properties, the second concentrates on mechanical performance, and the third deals with functional performance, including wide application areas ranging from mechanical cutting to solar energy and from electronics to medicine.
There has always been a close connection between physics and music. From the great days of ancient Greek science, ideas and speculations have passed backward and forward between natural philosophers (physicists) and musical theorists. Measured Tones: The Interplay of Physics and Music, Second Edition explores the story of that relationship in an entertaining and user-friendly way.
Environmental Noise Barriers is a unique one-stop reference for practitioners, whether acoustical engineers, landscape architects, or manufacturers, and for highways departments in local and central authorities. This extensively revised new edition is updated in line with UK and EU legislation and international provision of barriers.
This book presents a MATLAB®-based approach to solving the problems of undesirable noise generation and transmission by structures and of undesirable vibration within structures in response to environmental or operational forces. The book will be of considerable interest to the student of vibration and noise control and also to academic researchers working in the field. It’s tutorial features will help practitioners who wish to update their knowledge with self-study.The fundamentals of acoustics, vibration and coupling between vibrating structures and the sound fields they generate are introduced including a discussion of the finite element method for vibration analysis.
