Localization based on enhanced low frequency interaural level difference

The processing of low-frequency interaural time differences is found to be problematic among hearing-impaired people. current generation beamformers does not consider this deficiency. In an attempt tackle issue, we propose replace the inaudible in region with level differences. addition, a beamformer introduced and analyzed, which enhances sound sources using near-field transformation. proposed beamforming problem relaxed convex semi-definite relaxation. instrumental analysis suggests that are enhanced without hindering provided intelligibility. A psychoacoustic localization test done listening experiment, replacement into improves performance normal-hearing listeners for anechoic scene but reverberant scene.
