The Book Provides Detailed Noise-controlling Strategies For Devices Generating Excessive Noise. The Main Three Categories Are Passive, Semi-active And Active, And Are Applicable To A Wide Range Of Devices, With Applications Including Vehicle Or Aircraft Cabins. With Noise Pollution A Pressing Concern World-wide, This Book Uses Cutting Edge Technology To Provide Methods To Reduce Noise At The Source. Some Of The Most Common Noise And Vibration Sources Are Devices And Machinery, And Commonly Used Sound-absorbing Methods Are Ineffective, Often Causing Further Problems Such As Increased Size, Weight And Potential To Overheat. This Book Solves These Issues Through Providing Three Solutions: Passive, Semi-active And Active. Focusing On Global Noise Reduction, Compact Technology And Efficiency, The Research Presented Acts Directly At The Source, Isolating It Acoustically From The Environment. Proposing A Range Of Specific Control Strategies For Noise-controlling Casings, The Book Provides A Theoretical Background To The Research, Looking At System Configurations, Signal Processing Implementation And Numerical Analysis. This Book Will Be Of Interest To Professionals And Students In The Field Of Acoustics, Signal Processing, Automotive And Aircraft Engineering-- Provided By Publisher.
