Automatic Selection of Reduction or Enhancement of Transient Sounds

摘要

A system and method of generating electrode stimulation signals for electrode contacts in an electrode array associated with a hearing implant is presented. An input audio signal is processed to generate a plurality of band pass channel signals each representing an associated band of audio frequencies. A stationary noise reduction is applied so as to provide a stationary noise reduced channel envelope from each channel signal. A transient in one or more of the channel envelopes is detected. The channel envelopes are modified as a function of whether the transient is transient noise or transient speech, so as to form transient modified envelope. The transient modified envelopes are used to generate electrode stimulation signals to the electrode contacts.

1. A method of generating electrode stimulation signals for electrode contacts in an electrode array associated with a hearing implant, the method comprising:
processing an input audio signal to generate a plurality of band pass channel signals each representing an associated band of audio frequencies; applying stationary noise reduction so as to provide a stationary noise reduced channel envelope from each channel signal; detecting a transient in one or more of the channel envelopes; modifying the channel envelopes as a function of whether the transient is transient noise or transient speech, so as to form transient modified envelopes; and using the transient modified envelopes to generate electrode stimulation signals to the electrode contacts.
