Sound Source Localization with a Large Number of Blinkies

摘要

Sound-to-light conversion has a long history forrnvisualization and communication . It has alsornbeen used for the study of frog chorus in the field .rnRecently, we proposed such sensors, termed blinkies,rntogether with a video camera, as a practical wayrnof extending multichannel audio acquisition to radi-rncally large scale scenarios where sensors in the hun-rndreds can easily be distributed over a large area withrnfew constraints. Fig. 1 illustrates the system. Inrnthis previous work, we explored sound source local-rnization through numerical simulation with only arnfew blinkies and an algorithm from Chen et al.,.
