Zusammenfassung:To address the technical problem of varying gain applied to different hearing impaired (HI) patients, a technical solution described herein includes application of a patient-specific noise reduction algorithm based on a patient-specific signal-to-noise ratio (SNR) loss function. HI patients vary in their ability to extract information in a given signal-to-noise ratio (SNR) environment. However, noise reduction algorithms often include a single noise reduction function for all SNR loss functions. For a HI patient with significant SNR-loss, they will receive little noise reduction in SNR conditions where the patient gains no benefit from the sound. Technical solutions described herein includes determining a HI patient's ability to extract information for various SNR values, and then using specific NR algorithm attenuation for specific SNR values according to the HI patient's determined ability to extract information.
