Abstract: A method for adjusting parameters of a hearing prosthesis system includes adjusting a control to shift an audiogram associated with a first stimulator, applying a prescription rule using the shifted audiogram to adjust a cross-over frequency that defines a first frequency range and a second frequency range. The first stimulator is configured to apply stimulation signals in the first frequency range and a second stimulator is configured to apply stimulation signals in the second frequency range. The method also includes applying the prescription rule using the shifted audiogram to determine gain and maximum power output (MPO) levels for the first frequency range associated with the first stimulator.

Abstract: A method and system for fitting and adjusting the operation of an acoustic hearing prosthesis or a hybrid electric and acoustic hearing prosthesis. A graphic user interface allows for the acoustic and electric fitting parameters to be viewed and adjusted in a comparable way. The method further allows for the parameters for acoustic stimulation of the acoustic channels to be adjusted in response to behavioral or objective measurement of response to known stimuli, so as to achieve a desired response curve.

Abstract: The present application discloses systems, methods, and articles of manufacture for determining prescription rules for a hearing prosthesis. A method in accordance with the present disclosure includes identifying a threshold hearing level and an uncomfortable loudness level for a channel of a hearing prosthesis. In one example, the threshold hearing level and the uncomfortable loudness level are determined in response to a stimulation signal generated utilizing the hearing prosthesis in situ on a recipient. In the present example, the stimulation signal corresponds to the channel of the hearing prosthesis. The method further includes developing a prescription rule based on the threshold hearing level and the uncomfortable loudness level. Generally, the prescription rule includes at least one of a linear compression scheme and a wide dynamic range compression scheme.

Abstract: Methods and systems are disclosed for determining an amplitude of one or more stimulation signals corresponding to a subject signal for use by a stimulating medical device having a first group of stimulation channels mapping to a second group of electrodes, respectively. Such a method, for example, includes: obtaining the subject signal; filtering the subject signal with a first plurality of band-pass filters (BPFs) having substantially contiguous pass-bands, respectively, to obtain a first set of one or more signals; selecting at least one of the stimulation channels based on the first set; filtering the subject signal with a second plurality of BPFs having significantly overlapping pass-bands, respectively, to obtain a second set of one or more signals; and determining at least one stimulation amplitude for the at least one selected stimulation channel, respectively, based on the second set of signals.

Abstract: A cochlear prosthesis comprising an electrical signal analyser configured to process a first frequency sub-range of a detected sound signal for electric stimulation of the cochlea, and a delay circuit configured to impose a delay on at least one of an electrical signal delivery path and an acoustic signal delivery path, to provide for delivery of the electrical stimulation to the cochlea at a desired time relative to a time of arrival of acoustic stimuli at the cochlea, wherein the acoustic stimuli arriving at the cochlea and the electrical stimulation delivered to the cochlea at the desired time substantially simultaneously stimulate the cochlea.

Abstract: Methods and systems are disclosed for determining the stimulation channels for application of stimulation by a medical device, such as a cochlear implant or an auditory brain stimulator. In embodiments, the medical device filters a received signal to obtain a plurality of band-pass filtered signals, each corresponding to one or more stimulation channels. The medical device then selects a stimulation channel for application of stimulation based on the amplitudes of the band-pass filtered signals. The medical device determines whether to apply stimulation on the adjacent stimulation channels by determining if the amplitude of the corresponding adjacent stimulation channel exceeds an information limit. If the amplitudes for either adjacent channel fall below the information limit, the corresponding adjacent stimulation channel is eliminated from consideration.
