GPS enabled efficient sound source localisation using microphone array

Abstract

In this era of rapid technical developments in the field of sound source localisation, there is an urgent need to integrate these individual technologies to create an accurate and more power localiser. When the technique volumetric steered response power (V-SRP) is compared to steered response power (SRP), the former achieves a significant lower computational complexity. This is achieved without much decrease in the accuracy of location estimation. By appending a fine search stem to V-SRP, a refined version (RV-SRP) is achieved with improved compromise of complexity and accuracy. Experiments are performed using both the simulated as well as real scenario data to demonstrate the decrease in the computational cost. Further, in the experiment, the global positioning system (GPS) provides the accurate location coordinates of the source. It is to report newly developed system and methodologies which will be able to find approximate azimuth and elevation angle of sound source with integration of TDE-ILD-HRTF along with geo-positioning visualisations to help humanity to achieve its goal towards peace and harmony.
