摘要:
A hearing assistance device and method is presented. An electrode is configured to be disposed within a cochlea of a user. A processor is in communication with the electrode and is configured to stimulate the electrode. The processor is configured to receive an input audio signal, band-pass filter the input audio signal into a plurality of channel signals, apply a Hilbert transform to at least one of the plurality of channel signals to generate a transformed audio signal, and analyze the transformed audio signal to identify at least one positive-moving zero crossing of the transformed audio signal. Upon identifying the at least one positive-moving zero crossing of the transformed audio signal, the processor is configured to trigger an electric current pulse to be delivered to the electrode.
