Description
Peng Zhang, Hongyuan Wen, Zhiyong Xu, and Zhao Zhao present a noise-hardy way to measure the time gap between two sensors hearing the same sound, in this 2023 paper. That gap pins down where a sound came from, but background noise scrambles it. Their method leans on a simple split: noise splashes arrive with random delays, while true signal points share one lag.
A four-step routine roughs out the delay, rearranges the time-frequency picture to part signal from noise, keeps the points flanking the delay ridge, and then refines the estimate. A sharpened second-order variant packs the signal energy tighter. In simulations and bench tests, the approach beat existing methods on both accuracy and robustness.
