A Survey of Sound Source Localization Methods in Wireless Acoustic Sensor Networks

<div>Node communication steps in CUSUM-based TOA estimation. (a) One of the nodes detects the sound event and sends an event warning alert to the other nodes. (b) The nodes estimate their TOAs and send it to a central node.</div>
