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.

A system for validation of a hearing aid performance, especially in small children is disclosed. The validation of the performance of hearing aids after having being fitted to a small child who is not able to subjectively provide responses to sounds presented to the child via the hearing aids, is instead done in an objective manner, by using a naturally occurring signal, which has been modulated in order to create an ASSR evoking speech stimulus which is not considered as noise by a hearing aid.

A method for operating a hearing instrument, wherein a biometric parameter of a wearer of the hearing instrument is acquired by a sensor of the hearing instrument and/or an electrical input signal is generated from an ambient sound by at least one microphone of the hearing instrument, and the presence of a specific ambient acoustic situation is detected from a plurality of different ambient acoustic situations by an analysis of the input signal, based on the acquired biometric parameter or the detected ambient acoustic situation a critical stress level of the wearer is determined, and then, in accordance with the critical stress level thus determined, a parameter of a signal processor of the hearing instrument is adjusted to a predefined parameter value.
