Abstract

Sound source localization using a microphone array embedded on an unmanned aerial vehicle has been studied to detect and localize people who need help in a disaster-stricken area. Because such sound source localization should work in outdoor environments, the design of the microphone array is crucial. We thus developed two types of microphone array; 16ch two-storied hexagonal and 12ch spherical microphone arrays. These two microphone arrays were evaluated via numerical simulation with discussions on the appropriate design of microphone arrays.
