20120109006 | FITTING AN AUDITORY PROSTHESIS - 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 behavioural or objective measurement of responses to known stimuli, so as to achieve a desired response curve. | 05-03-2012 |

20080319508 | Automatic Determination of the Threshold of an Evoked Neural Response - Automatically analysing an evoked neural response. The method comprises: applying electrical stimulation to a target neural region at incrementally greater current levels beginning with an initial current level that is as close as possible to a typical threshold-NRT level; recording an NRT measurement of an auditory signal which generated by the target neural region in response to the stimulation; and utilizing a machine-learned expert system to predict whether the NRT measurement contains a neural response based on a plurality of features extracted from the auditory signal. | 12-25-2008 |
20130006328 | SIMULTANEOUS DELIVERY OF ELECTRICAL AND ACOUSTICAL STIMULATION IN A HEARING PROSTHESIS - 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. | 01-03-2013 |
20140350640 | Implantable Medical Device and Tool Sensors - Implantable medical devices and instruments (tools) including one or more implantable sensors. In certain embodiments, a hearing prosthesis comprises an implantable stimulating assembly configured to be implanted in a recipient's cochlea. At least one implantable sensor is disposed in the implantable stimulating assembly and is configured to monitor an insertion attribute. | 11-27-2014 |

20110077712 | SOUND PROCESSING METHOD AND SYSTEM - Coding of received audio signals and the resulting application of electrical stimuli applied to electrodes used in a cochlear implant system are disclosed together with a method of fitting this new coding strategy. One of the aims is to place specific stimulation representing pitch by applying near threshold electrical stimuli with limited and focussed excitation fields. A range of stimulation rates and a minimal range of current levels above threshold are used for creation of a dynamic loudness percept for a cochlear implant recipient. Another aim is to disclose a coding scheme based on a model of physiological measures (i.e. refractoriness, adaptation, spread of activation field, spatiotemporal acoustical cochlear activation patterns and spontaneous activity) to estimate the proportions of available excitable auditory neurons close to the electrodes available for stimulation. The spectral bands formed from the pre-processing of incoming audio signals are weighted by these proportions of excitability to control place, timing, rate and current level of electrical stimuli applied to the electrodes available in the array. | 03-31-2011 |
