Abstract
A computing system comprises an auditory system exposed to an environment. The auditory system comprises a microphone that receives sonic waveforms and outputs audio signals. A baffle structure comprising multiple paths for every arriving sonic waveform is located between the microphone and the environment. The baffle structure is configured to, based at least on an angle of arrival for a sonic waveform, induce frequency dependent amplitude differences and phase differences for the sonic waveform over a range of frequencies. A processing system is communicatively coupled to the microphone. The processing system is configured to receive audio signals from the microphone representing the sonic waveform, to identify a source of the sonic waveform based at least on the received audio signals, and to output an estimated angle of arrival for the sonic waveform based at least on amplitudes and phases of the received audio signals and characteristics of the baffle structure.
