摘要：
An exemplary system includes a detection facility configured to detect an input sound level of an audio signal presented to an auditory prosthesis patient； and an adaptive gain control (AGC) facility configured to 1) determine whether the detected input sound level is in a quiet region, an intermediate region, or a loud region, and 2) apply a gain to the audio signal in accordance with an AGC gain function that specifies the gain to be substantially equal to or less than a first gain threshold if the detected input sound level is in the quiet region, substantially equal to or less than a second gain threshold if the detected input sound level is in the loud region, and greater than the first and second gain thresholds if the detected input sound level is in the intermediate region. Corresponding systems and methods are also disclosed.
