Existing real-time passive sound localization systems are mainly based on the time-difference-of-arrival (TDOA) approach, limiting sound localization to two-dimensional space, and are are not practical for use in noisy conditions.
Existing real-time passive sound localization systems are mainly based on the time-difference-of-arrival (TDOA) approach, but this limits sound localization to two-dimensional space. The most important problem is that TDOA sound localization systems are not practical for use in noisy conditions.
