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 EditionRevised, expanded, and updated information in every chapterAdvances in feedforward control algorithms, DSP hardware, and applicationsPractical application examples of active control of noise propagating in ductsThe use of a sound intensity cost function, model reference control, sensing radiation modes, modal filtering, and a comparison of the effectiveness of various sensing strategiesNew material on feedback control of sound transmission into enclosed spacesNew 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 controlA completely revised chapter on control system implementationNew material on parametric array loudspeakers, turbulence filtering, and virtual sensingMore material on smart structures, electrorheological fluids, and magnetorheological fluidsIntegrating 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 gathers the latest advances and innovations in the field of flow-induced vibration and noise, as presented by leading international researchers at the 4th International Symposium on Flow-Induced Noise and Vibration Issues and Aspects (FLINOVIA), which was held in Sydney, Australia, in May 2023.

This book gathers the latest advances and innovations in the field of flow-induced vibration and noise, as presented by leading international researchers at the 4th International Symposium on Flow-Induced Noise and Vibration Issues and Aspects (FLINOVIA), which was held in Sydney, Australia, in May 2023. It explores topics such as turbulent boundary layer-induced vibration and noise, noise due to ingested turbulence, rotor noise, fluid-structure interaction problems, innovative measurement methods, and noise control techniques. The authors’ backgrounds represent a mix of academia, government, and industry, and several papers include applications to important problems for underwater vehicles, aerospace applications, and commercial transportation. The book offers a valuable reference guide for all those interested in measurement, modelling, simulation, and reproduction of the flow excitation and flow-induced structural response.

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.
