HASPI tracks directionality, spatial noise and reverberation effects on hearing aid output intelligibility at the group level, yet supra-threshold processing—not electro-acoustic SNR gain—best explains individuals’ benefits.
This study reveals that normal hearing individuals present with different profiles on vertical sound source localization wherein discrimination remains robust, identification abilities—especially in up-down and front-back localization, underscoring the need for comprehensive virtual spatial hearing assessments.
Using psychometric procedures for estimating Minimum Audible Angle thresholds, the study demonstrated that increased spectral complexity and higher presentation levels significantly enhance spatial resolution in normal-hearing individuals.
Implementation of a Bionic Acoustic Camera using an artificial head, to be used as a demonstrator for spatial hearing mechanisms and an algorithm testing platform.
