Adaptive hearing normalization and correction system with automatic tuning

Abstract

A hearing normalization and correction system and process provides accurate correction for users with mild to moderate hearing loss by using actual measured hearing response at multiple sound pressure levels. User measured hearing data is collected at considerably higher resolution and accuracy at multiple sound pressure levels and is automatically converted to multiple accurate correction responses. Dynamic adaptive cross-fade response correction is used to deliver hearing normalization at varying sound pressure levels. Adaptive release response allows the hearing normalization system to accurately track the envelope of the incoming audio signal providing greatly enhanced accuracy and transparency. Adaptive headroom control is also applied to increase both input and output headroom providing professional dynamic range performance. The hearing normalization and correction system delivers audio fidelity and performance transcending that of normal hearing aid technology.
