Dynamic welding process monitoring based on microphone array technology

Journal of Manufacturing Processes, 2021
In this paper, microphone array technology was used to monitor the dynamic pulsed GMAW process. At first, the splash sound signal is successfully separated out based on FastICA blind signal separation algorithm, and its frequency domain energy ...

An Analytical Method for 3-D Sound Source Localization Based on a Five-Element Microphone Array

IEEE Transactions on Instrumentation and Measurement, 2022
An analytical method for 3-D sound source localization based on a five-element microphone array is proposed in this work. With four time-difference-of-arrival (TDOA) values, the proposed method realizes the sound source localization by analytical ...
