A Data-driven Distance Metric for Evaluating the effects of Dynamic Range Compression in Adverse Conditions.

ABSTRACT: Dynamic range compression is a crucial component in hearing aids, aiming to restore audibility for hearing-impaired listeners. However, determining suitable compression parameters, such as the time constants for the level estimation stage, remains a topic of debate, as the perceptual benefit of different parameter configurations varies depending on the acoustic conditions. In this study, a data-driven distance metric based on physical metrics was developed to evaluate and compare the performance of various compression systems. This analysis encompassed fast-acting and slow-acting compression, as well as a "scene-aware" compression that dynamically adjusted the release time constant based on the presence of the target. A reference system called "source-independent compression" was also cons
