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. It also details the pitfalls one must avoid to ensure a reliable and stable system.

This book highlights the importance of sound produced by fluid flow or flow-induced noise. Noise created by unsteady flow creates high levels of environmental noise pollution, a known public health problem, and can compromise the acoustic qualities of marine vessels. There is a seemingly ever-growing list of modern technology that created flow-induced noise which includes aircraft, wind turbines, submarines, drones, high-speed rail, and cooling fans. More scientists and engineers are required to incorporate the effects of flow-induced noise in their work. This book also provides a comprehensive introduction to the theory underpinning the understanding of flow-induced noise.

FIND AND USE THE INFORMATION YOU NEED TO ACHIEVE YOUR FINANCIAL GOALS

With the boom in investor newsletters, magazines, and cable and Internet resources, the average person now has access to more crucial investment information than big-time money managers did 20 years ago. But having it and knowing what to do with it are two different things. With so much nonstop information and advice coming at you from hundreds of different directions, it's hard not to become confused, or worse, led astray by unscrupulous tipsters and scam artists.

In Getting Started in Financial Information, veteran financial journalists Daniel Moreau and Tracey Longo tell you how to mine the precious nuggets from the mountain of investor information. No matter what your investment goals or level of experience, you'll learn how to locate, interpret, and profitably apply all the important information you need to achieve your financial objectives. Among other valuable lessons, the authors show you how to:

• Recognize the difference between opinion and real news
• Research effectively in all print and electronic media
• Gauge the value of newsletters and online services
• Read between the lines in annual reports
• Focus on what's really important in stock tables
• Decipher mutual fund prospectuses
• Access 1, 3, and 5 year mutual fund returns-quickly and painlessly
• Obtain valuable information on risk and market performance
