A system comprises an auditory device processor, an auditory device output mechanism, an auditory input sensor, a database including a reference bank of environmental sounds and corresponding sound profiles, and a memory. The auditory device processor is configured to: while the auditory input sensor is detecting a first environmental sound, receive a sound selection from the user, wherein the sound selection is associated with the first environmental sound; store a first sound profile in the reference bank corresponding to the first environmental sound; receive a second environmental sound detected by the auditory input sensor; analyze a frequency content of the second environmental sound; compare the frequency content of the second environmental sound with the reference bank of environmental sounds and corresponding sound profiles stored in the database; in response to the comparison, select one of the sound profiles corresponding to the second environmental sound; and automatically adjust the parameter settings.

Presented herein are techniques for determining an optimal or selected placement for an in-the-ear (ITE) coil configured to be removably positioned within an ear canal of a recipient of an implantable auditory prosthesis that comprises an implantable coil positioned adjacent to the ear canal of the recipient. The optimal placement for the ITE coil is used to fabricate/produce an ITE component that is configured to be worn within the ear canal of the recipient. The ITE component is constructed with an arrangement such that, when the ITE component is fittingly inserted into the ear canal, the ITE coil will be situated at the optimal placement within the ear canal. At the optimal placement, the ITE coil is configured to efficiently communicate with the implantable coil positioned adjacent to the ear canal of the recipient.

An exemplary evoked response measurement system includes a sound processor external to a patient and configured to direct a cochlear implant implanted within the patient to apply electrical stimulation to the patient. The measurement system also includes a headpiece configured to connect to the sound processor by way of a cable, affix to an external surface of a head of the patient, and facilitate wireless communication between the sound processor and the cochlear implant. The measurement system also includes a plurality of conductive contacts communicatively coupled to the sound processor and affixed to the external surface of the head of the patient to detect a signal representative of an evoked response generated by a brain of the patient in response to the electrical stimulation. At least one conductive contact is physically coupled to the headpiece and located between the headpiece and the external surface of the head of the patient.

A navigation system or combination of navigation systems can be used to provide one or more navigation modalities to track a position and navigate a single instrument in a volume. For example, both an Electromagnetic (EM) and Electropotential (EP) navigation system can be used to navigate an instrument within the volume. The two navigation systems may be used separately to selectively individually navigate the single instrument in the volume. Disclosed are also systems and processes to determine a shape of the single instrument either alone or in combination with the position of the instrument. The instrument may be navigated with the addition of tracking devices or with native or inherent portions of the instrument.

A method includes receiving first information regarding a pose of a structure in a first time period. The structure is configured to be inserted into a body portion of a recipient. The first information includes at least one of: a first estimate of the pose of the structure in the first time period, and a first measurement set including one or more first measurement values. At least some of the one or more first measurement values are generated using a plurality of sensors distributed along the structure. The one or more first measurement values are indicative of the pose of the structure in the first time period. The method further includes generating a second estimate of the pose of the structure using at least the first information and a probabilistic model of the structure and/or the body portion.

A sparse signal space model for a set of tissue response recordings has a signal space separable into a plurality of disjoint component manifolds including a neural action potential (NAP) component manifold corresponding to tissue response to electrical stimulation signals. A response measurement module is configured to: i. map a tissue response measurement signal into the sparse signal model space to obtain a corresponding sparse signal representation, ii. project the sparse signal representation onto the NAP component manifold to obtain a sparse NAP component representation, iii. when the sparse NAP component representation is greater than a minimum threshold value, report and recover a detected NAP signal in the tissue response measurement signal.

An optimization system for testing a patient's hearing comprises a controller, an ear piece, and a memory. The controller: provides a series of tones to the ear piece; receives feedback from the patient between each tone; generates a data point to be used in an audiogram after receiving each feedback; after each data point is generated, computes a statistical distribution based on the generated data points; identifies an area of the statistical distribution most in need of additional data; and selects a subsequent tone to provide in the series of tones. Each feedback indicates whether the respective tone was detected or not detected, and each data point is based on the respective feedback. Each subsequent tone provided in the series of tones is a tone represented in the area of the statistical distribution most in need of additional data at the time of selection.
