Active Control of Sound
TLDR
This book brings together results from research in the two disciplines of acoustics and signal processing and presents the fundamentals of noise control in a unified manner. Expand
Active noise control
TLDR
Active noise control exploits the long wavelengths associated with low frequency sound. Expand
A multiple error LMS algorithm and its application to the active control of sound and vibration
TLDR
An algorithm is presented to adapt the coefficients of an array of FIR filters, whose outputs are linearly coupled to another array of error detection points, so that the sum of all the mean square error signals is minimized. Expand
Active control of vibration, 1st edition
This book is a companion text to Active Control of Sound by P.A. Nelson and S.J. Elliott, also published by Academic Press. It summarizes the principles underlying active vibration control and itsExpand
Aerodynamic sound production in low speed flow ducts
Abstract Measurements of spoiler aerodynamic noise, generated in a low velocity flow duct and radiated from an open exhaust termination, have been made in the form of sound power spectra. TheExpand
ESTIMATION OF ACOUSTIC SOURCE STRENGTH BY INVERSE METHODS: PART I, CONDITIONING OF THE INVERSE PROBLEM
This paper deals with the discrete inverse problem in acoustics. It is assumed that a number of acoustic sources are located at known spatial positions and that the acoustic pressure is measured at aExpand
Multiple-Point Equalization in a Room Using Adaptive Digital Filters
A method is presented for designing an equalization filter for a sound-reproduction system by adjusting the filter coefficients to minimize the sum of the squares of the errors between the equalizedExpand
Fast deconvolution of multichannel systems using regularization
TLDR
A very fast deconvolution method, which is based on the fast Fourier transform (FFT), can be used to control the outputs from a multichannel plant comprising any number of control sources and error sensors. Expand
Digital filter design for inversion problems in sound reproduction
When it is attempted to invert, or eliminate the influence of, a single-channel system such as a loudspeaker response or a room response, some frequencies are usually boosted by an excessive amountExpand
Boundary element simulations of the transfer function of human heads and baffled pinnae using accurate geometric models
This paper investigates various aspects of numerically modelled individualised head-related (and pinna-related) transfer functions (HRTF). The computer simulations are based on the exact solution ofExpand
