NOISE AND VIBRATION ANALYSIS
 
Complete guide to signal processing and modal analysis theory, with coverage of practical applications and a plethora of learning tools
 
Featuring numerous line diagrams and illustrations, the newly revised and updated Second Edition of Noise and Vibration Analysis is a comprehensive and practical guide that combines both signal processing and modal analysis theory with their practical application in noise and vibration analysis. This new edition has been updated with three new chapters covering experimental modal analysis, operational modal analysis, and practical vibration measurements.
 
Taking a practical learning approach, the text includes exercises that allow the content to be developed in an academic course framework or as supplementary material for private and further study, including multiple choice questions at the end of each chapter. An accompanying website hosts a MATLAB(r) toolbox, additional problems and examples, and videos.
 
Written by a highly qualified author with significant experience in the field, Noise and Vibration Analysis covers topics such as:
* Dynamic signals and systems, covering periodic, random, and transient signals, RMS value and power, and the Continuous Fourier Transform
* Time data analysis, covering the sampling theorem, analog, digital, smoothing, and acoustic octave filters, time data differentiation, and FFT-based processing
* Statistics and random processes, covering expected value, errors in estimates, and probability distribution in random theory, and tests of normality and stationarity
* Fundamental mechanics, covering Newton's laws, alternative quantities for describing motion, frequency response plot formats, and rotating mass
 
Noise and Vibration Analysis is an excellent resource for researchers and engineers from the automotive, aerospace, mechanical, or electronics industries who work with experimental or analytical vibration analysis and/or acoustics. The text is also valuable for graduate students enrolled in vibration analysis, experimental structural dynamics, or applied signal analysis courses.
