Abstract
A low latency hearing device includes a first sound receiver and a processor. The processor includes a predictor. The first sound receiver is configured to receive an input sound signal. The processor is configured to execute following steps according to the plurality of commands of the memory: predicting a noise reduction (NR) filter by the predictor for a current frame of the sequence of frames based on a previous frame of the sequence of frames that precedes the current frame; filtering the current frame using the predicted NR filter to generate a filtered sound signal; and outputting the filtered sound signal.
