Bio-inspired coincidence detector for the geolocation of a sound source
We have developed a bio-inspired coincidence detector that allows the spatial geolocation (2D/3D) of a sound signal source or a target reflecting a signal, in a quasi-instantaneous way and with low energy cost.
This system can be used in many industrial applications:
This system can be used in many industrial applications:
- Leak detection and geolocation in the industry
- Improvement of noise monitoring on construction sites
- Improvement of supervision of industrial machinery monitoring and anomaly detection
- etc.



Solution
Our patented solution is based on a coincidence detector that, just like in the context of neurobiology, helps to distinguish the correlation and occurrence of two signals close in time, which represent the main mechanisms of auditory localization:
- ITD (Interaural Time Difference)
- ILD (Interaural Level Difference)

The interpretation of these metrics in an appropriate processing system allows the geolocation of the sound source.
The advantages of our geolocation detector are mainly:
