Abstract
An exemplary hearing device includes a memory storing instructions and a processor communicatively coupled to the memory. The processor may be configured to execute the instructions to receive an input audio signal having a range of input frequencies, adaptively adjust a cut-off frequency for the input audio signal such that a value of the cut-off frequency varies between a predefined minimum cut-off frequency value and a predefined maximum cut-off frequency value as a continuous function of the input audio signal, and generate an output audio signal by mapping the range of input frequencies to a range of output frequencies determined based on the adaptively adjusted cut-off frequency.
