US Patent 12028684 Spatially differentiated noise reduction for hearing devices

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.
