Acoustic emission leak source location
The Journal of the Acoustical Society of America, 1992A method and apparatus for locating a leak which produces a continuous acoustic emission having background noise and spikes, comprises continuously monitoring the acoustic emissions using spaced apart detectors which produce signals having background noise and spikes corresponding to those of the continuous acoustic emissions.

Acoustic source location using a neural network
The Journal of the Acoustical Society of America, 1997This paper presents an artificial neural network (ANN) approach to locate an acoustic source and determine its distance from a microphone. First, two sets of experiments were performed to locate a rattling bolt on a plate using the unwrapped phase method, by comparing the acceleration signal from the vibrating plate to the acoustic signal received by ...

Delta T source location for acoustic emission
Mechanical Systems and Signal Processing, 2007Acoustic emission (AE) source location provides a powerful tool for the engineer. Current methods, time of arrival (TOA) location and single sensor modal analysis location (SSMAL), are based on assumptions derived from a simplistic structure. In complex geometric structures these assumptions are incorrect.

Graphics of acoustic emission point source location
Proceedings. IEEE Energy and Information Technologies in the Southeast', 2003Spherical coordinates of acoustic emission point-sources are computed using test data collected using a specialized hardware/computer and the software developed for this purpose. A data file of spherical coordinates thus obtained is used for a visual display of acoustic emission point-sources, leading to determination of developing failure patterns for

Estimation of the location of a farfield acoustic source
The Journal of the Acoustical Society of America, 2005A backward integration method for estimating the location of a source of sound waves in the atmosphere is presented. This geometric acoustics method is based upon the analysis of microphone array measurements to determine the incoming ray direction in three dimensions.

Multiple Acoustic Sources Location Based on Blind Source Separation
2005In this paper we study location of multiple acoustic sources by blind source separation (BSS) method, which based on canonical correlation analysis (CCA). The receiving array is a sparse array. This array is composed of three separated subarrays. From the receiving data set, we can obtain the separate components by CCA. After a simple correlation, time
