AI Technical Summary

Technical Problem

Conventional sound source localization methods using variational inference require significant computational resources, making them unsuitable for real-time localization in dynamic environments.

Method used

A sound source localization apparatus that employs Projection Approximation Subspace Tracking (PAST) to calculate signal and noise subspaces without eigenvalue decomposition, combined with Delay-Sum Array and stochastic gradient descent to identify candidate vectors and optimize direction estimation, reducing computational load and enabling real-time localization.

Benefits of technology

The method achieves real-time sound source localization with high accuracy and reduced computational complexity, capable of tracking moving sources with minimal error.
