Experimental Research on Rapid Localization of Acoustic Source in a Cylindrical Shell Structure without Knowledge of the Velocity Profile

open access: yesSensors, 2021
Acoustic source localization in a large pressure vessel or a storage tank-type cylindrical structure is important in preventing structural failure. However, this can be challenging, especially for cylindrical pressure vessels and tanks that are made of ...

Through-Ice Acoustic Source Tracking Using Vision Transformers with Ordinal Classification

open access: yesSensors, 2022
Ice environments pose challenges for conventional underwater acoustic localization techniques due to their multipath and non-linear nature. In this paper, we compare different deep learning networks, such as Transformers, Convolutional Neural Networks ...

Fast Bayesian acoustic localization [PDF]

open access: yesIEEE International Conference on Acoustics Speech and Signal Processing, 2002
We derive a probabilistic formulation, based upon Bayes' rule, for the acoustic localization problem. The resulting formula is shown to be closely related to the energy of a conventionally beamformed signal. We then present a close approximation to both which is much faster to compute — by two orders of magnitude with our experimental setup.

Acoustic Based Localization of Partial Discharge Inside Oil-Filled Transformers

open access: yesIEEE Access, 2022
This paper addresses the localization of Partial Discharge through a 3D Finite Element Method analysis of acoustic wave propagation inside a 3-phase 35kV transformer with the help of COMSOL Multiphysics software. Due to the complexity inside transformers,

Source Localization in Random Acoustic Waveguides [PDF]

open access: yesMultiscale Modeling & Simulation, 2010
Mode coupling due to scattering by weak random inhomogeneities in waveguides leads to loss of coherence of wave fields at long distances of propagation. This in turn leads to serious deterioration of coherent source localization methods, such as matched field.
