Abstract: 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.

Abstract: Disclosed herein, among other things, are systems and methods for spatially differentiated noise reduction for hearing device applications. A method includes sensing sound signals with a hearing device. A front-facing directional beam and a rear-facing directional beam are produced using the sensed sound signals, and the front-facing directional beam and the rear-facing directional beam are combined to obtain an output directional beam. The front-facing directional beam or the output directional beam is compared to the rear-facing directional beam to determine a front-rear differential. Responsive to a determination that the front-rear differential indicates that the rear-facing directional beam is dominant, the amount of noise reduction of the output directional beam is increased. Responsive to a determination that the front-rear differential indicates that the rear-facing directional beam is not dominant, an amount of noise reduction of the output directional beam is reduced.
