Product Description
The acoustic and vibration characteristics of vehicles remain vitally important factors to market success. Failure to meet customer expectations can seriously affect sales and ultimately company survival. Achieving appropriate quality and affordable costs is the engineering task that this volume addresses. "Vehicle Noise and Vibration 2002" includes contributions from across Europe covering technologies and applications from virtual vehicles to analysis methodology and from subsystems modelling and validations to the whole vehical approach. In view of the new measurement and assessment methodologies and better understanding of noise from brakes, this volume brings a collection of papers together under the following headings: brakes and friction induced NVH; virtual prototyping NVH engineering - best practice and challenges; driveline; whole vehicle; and powertrain. The text is aimed at executives, managers, specialists, engineers, scientists and all those concerned with NVH in the auto industry and supply chain companies.It should also be of interest to academics who are active - or considering working in - acoustics, vibration control and new measurement technologies in a dynamic environment. ...

Product Description
Gives basic requirements for reproducible methods for determining the sound power emitted by machines. The method is especially applicable in cases where direct measurements are not possible because of high background noise. The methods are only applicable to noise which is emitted by vibrating surfaces of solid structures and not to noise generated aerodynamically. ... Read more

Product Description
Discusses useful procedures in the design of industrial noise abatement systems and equipment to reduce the generation and transmission of noise to comply with standards of OSHA, the EPA, and HUD. ... Read more

Product Description

In this book, an international team of highly qualified experts treats important topics in "Acoustic Echo and Noise Control" and report the latest developments. Methods for enhancing the quality of transmitted speech signals are gaining growing attention in universities and in industrial development laboratories.

This book is organized in five parts: Part I gives a short introduction to acoustic echo and noise control. Part II deals with multi-microphone processing. In Part III, advanced methods for both linear and nonlinear echo cancellation are presented, and techniques for intelligent control of hands-free telephones are introduced. Part IV is devoted to noise reduction procedures. An in-depth treatment of conventional and of advanced methods is given, followed by a model based approach using Kalman filters. Finally, in Part V, selected applications of acoustic echo and noise control as well as speech and audio processing in general are outlined. Topics such as auditory scene analysis, wave field synthesis for spatial sound reproduction, in-car communication systems, and hearing aids are treated.

Product Description
"Aeroacoustic Measurements" provides a basis for assessing mechanisms of noise generation, and for developing methods of reducing noise to more acceptable levels. However, the measurements themselves are complex, and require a deep understanding of the experimental facility utilized (such as a wind tunnel), measurement instrumentation, and data analysis techniques. In this volume, recent advances in the measurement and understanding of aerodynamically generated sound are presented by leaders in the development of new techniques in this field. Both basic and applied problems are covered in detail. ... Read more

Product Description
This revised edition contains 30 pages of updated material presented in a supplemental format.This text covers the acoustical theory necessary to the practice of noise control. Example problems are used throughout to relate the basic laws of acoustics to practical applications. The book illustrates the uses of personal computers to evaluate noise problems and noise control techniques. Interpretation of data from measurements and theoretical predictions are emphasized, and alternative noise control techniques are examined. Real-world problems and case studies are used. Special features of this book are PC use integrated with noise control theory and practice; vector sound intensity and modal analysis; prediction methods for environmental impact, industrial noise, transportation noise; up-to-date OSHA, EPA and transportation noise standards and methods. ...

sophisticated maths treatment
Active noise cancellation is one of these nifty ideas that can be quickly described and understood using high school physics. And in the last 10 years, there have been more products out on in the marketplace, that apply this idea.

But if you want to delve deeper into the field, this book will give an appreciation of the complexity. Hansen takes you beyond a simple brochureware explanation. The subject combines electronics and mechanics, along with control systems. The discussion is sophisticated. Hopefully, the maths won't deter you. Though it can be formidable, even to someone with an undergraduate degree in engineering or the physical sciences.

He also gives a good discussion of the various commercial usages. ... Read more

Good Book on Noise but insufficient formulas
This book in industrial noise control has many useful information for beginners who want to learn about industrial noise but it does not have sufficient formulas on some important issues like estimating regenerated noise in ducts, pressure loss in air ducts and acoustic materials specs. I am expecting from a book like this for example to provide some information how noise is attenuated in lined ducts with respect to frequency, duct length and lining details. ... Read more

Advanced but thorough - a bible for the experienced acoustician
I have spent a number of years in the acoustics field and this book is the bible of industrial acoustics.

Having said that, this is not the "easiest" book to read and understand.It is aimed for those pursuing advanced studies in acoustics and acoustic control, with the assumption the reader has a thorough understanding of the fundamentals of math and physics.

The first few chapters in the book do give a brief introduction to sound (from a physics standpoint) and calculating sound levels for various sources.Anyone familiar with this information will recognize the information has not been significantly altered from Beranek's texts.Some information is given for current health & safety legislation but this is rather specific to the US.The initial chapters will not be adequate for someone new to the field of acoustics.

The "meat" of the book gives substantial treatment to noise control methods, noise in rooms, design of abatement equipment (both indoor and outdoor), industrial applications etc. however again the primary approach is from a mathematical/physics development.This does not mean one cannot immediately use the information effectively.The simple truth is noise abatement is not a "simple" field and the book doesn't attempt to "simplify" the complicated material.

The new edition of this book gives a good (if brief) description of the emerging field of active noise control.The primary limitation of this area is not the author's fault - there isn't enough practical data for active noise control at present.

One downfall of this book as a text is that very very few examples are provided for a student, and in the new version no chapter questions are included.For a student, I would recommend acquiring the 2nd edition of the text for the chapter questions.

Overally, an excellent resource for the experienced practioneer or advanced student. ... Read more
