Sound source localization is a crial capability for robots, enabing them to identify and respond to auditory cues in their environment. Traditional methods often rely on simple microphone arrays and basic signal procesing techniques. Howeveer, recent innovations have e importantly advanced this field, alluing robots to dosahovat more exacceate and real-time localization.

Traditional Techniques in Sound Source Localization

Historically, robots used methods such as th Time Difference of Arrival (TDOA) and beamforming. TDOA calculates the difference in arrival times of sound waves at multiple microphone to determinate the source direction. Beamforming endives focusing te microphone array 's sensitivity in specific directions to enhance sound detection.
