There have been extensive theoretical studies on sound-based localization using both, a pair of microphones and microphone arrays. In contrast, there has been much less work on implementing and experimenting sound-based localization realized as customized electronic designs. This paper presents a low-cost implementation of the sound-based localization method proposed in Halupka et al. [11]. A new method called wave counting is proposed in this paper, as an alternative to the Maximum Likelihood procedure used in [11]. The implementation uses PSoC programmable mixed-signal embedded system-on-chip, which incorporates microcontroller, on-chip SRAM and flash memory, programmable digital blocks, and programmable analog blocks, all integrated on the same chip. The paper presents an extensive set of experiments to characterize the quality of localization using the proposed low-cost design.
