Abstract: An exemplary system includes a sound processor configured to 1) divide an audio signal into a plurality of analysis channels and 2) generate one or more tonality indices each representing a tonality of one of the analysis channels, and an implantable cochlear stimulator communicatively coupled to the sound processor and configured to 1) generate one or more stimulation pulses configured to represent the audio signal in accordance with one or more stimulation parameters, and 2) adjust the one or more stimulation parameters based on at least one of the tonality indices.

Abstract: An exemplary signal processing unit includes 1) a microphone configured to detect one or more acoustic signals, 2) processing circuitry configured to process the one or more acoustic signals, and 3) a port configured to receive one or more electrodes that are configured to be placed on an outer surface of the head of a patient and to detect one or more central auditory potentials. The processing circuitry may be further configured to process the detected central auditory potentials.

Abstract: An exemplary method includes a sound processing subsystem 1) dividing an audio signal presented to an auditory prosthesis patient into a plurality of signals each representative of a distinct frequency portion of the audio signal and each contained within a distinct analysis channel included in a plurality of analysis channels, 2) determining a sound level of each signal included in the plurality of signals, and 3) setting an amount of noise reduction applied to each signal included in the plurality of signals in accordance with the determined sound level of each signal included in the plurality of signals. Corresponding methods and systems are also disclosed.

Abstract: An exemplary method includes a privacy management system 1) presenting, within a GUI, a patient list that initially includes a plurality of entries each comprising a plurality of obscured characters representative of patient information associated with a distinct patient included within a plurality of patients, 2) receiving user input representative of a search term comprising a sequence of one or more characters selected to identify a particular patient included within the plurality of patients, and 3) dynamically updating the patient list presented within the GUI in response to the user input by unobscuring a sequence of one or more obscured characters included in each entry of the patient list and that matches the sequence of one or more characters included in the search term and removing each entry included in the plurality of entries that does not include the search term from the patient list presented within the GUI.
