Sound Localization for Ad-Hoc Microphone Arrays

Sound localization is a field of signal processing that deals with identifying the origin detected sound signal. This involves determining direction and distance source sound. Some useful applications this phenomenon exists in speech enhancement, communication, radars medical as well. The experimental arrangement requires use microphone arrays which record methods involve using ad-hoc microphones because their demonstrated advantages over other arrays. In research project, existing have been explored to analyze disadvantages each method. A novel routine has formulated uses both arrival (DOA) along location estimation three-dimensional space precisely locate source. consists four single Previously, localized six or more microphones. precision increase research, however, we minimized reduce complexity algorithm computation time method results novelty by less resources providing are at par complex requiring additional tools average accuracy system found be 96.77% an error factor 3.8%.
