Methods and systems for modifying the parameters of at least one hearing device for a patient with residual hearing provide needed orchestration of acoustic and electric stimulation of patients wearing such devices.

Electric and acoustic stimulation fitting systems and methods

A method of measuring electrically evoked auditory brainstem responses of a patient or animal body is provided. The method includes surgically implanting an auditory prosthesis having an electrode array, the electrode array positioned either intracochlear or substantially proximate a brainstem of the body. At least one electrode is stimulated in the electrode array. Electrically evoked auditory brainstem responses resulting from said stimulation are recorded using, at least in part, an electrode in the electrode array as a negative electrode, and a positive electrode positioned substantially proximate the vertex of the head of the body.

Electrically evoked brainstem response measurements via implant prosthesis

A hearing device has a housing and a first electrode arranged to abut the skin of the individual. The hearing device further comprises at least two different elements selected from the group comprising: a brain-wave measurement circuit receiving measurement signals from the first electrode and from a second electrode arranged to abut the skin of the individual; a communication circuit receiving communication signals from and/or transmitting communication signals to the first electrode; a touch-sensing circuit transmitting sensing signals to the first electrode; a thermoelectric generator thermally connected to the outer surface of the housing mainly through the first electrode; and a charge control circuit sinking a charging current in dependence on a voltage across the first electrode and a third electrode.

The application relates to a hearing assistance device comprising an implanted part and to a method of its operation. The disclosure aims at improving the identification and processing of recorded nerve response data in an implanted part. The implanted part comprises a) A multitude of electrodes; b) Stimulation circuitry electrically coupled to a stimulation electrode during a stimulation time period; c) Measurement circuitry electrically coupled to a recording electrode during a measurement time period; d) A control unit configured to control the timing of the application of the stimulation signal in the stimulation time period and to control the measurement time period relative to the stimulation time period; and e) A processing unit configured to record the measured signal in the measurement time period and to identify a response from the auditory nerve based on said measured signal. The invention may e.g. be used for cochlear implant type hearing aids.

Hearing assistance device comprising an implanted part for measuring and processing electrically evoked nerve responses

A system for determining cochlear implant operating parameters for electrode contacts in an implantable electrode array. A first electrode contact is stimulated with an initial stimulation signal, and a channel fitting process is performed including: checking for a channel fitting response condition; if present then setting a channel operating parameter for the current electrode contact based on the channel fitting response condition, and ending the channel fitting process if parameters have been set for all electrode contacts. Otherwise, if the channel fitting response condition is not present or if channel operating parameters have not been set for all electrode contacts: selecting a next electrode contact, changing the stimulation level by a channel fitting increment, if a stimulation level limit has been reached, ending the channel fitting process, otherwise, stimulating the currently selected electrode contact with the stimulation signal at the current stimulation level and repeating the channel fitting process.

Progressive parameter scan for cochlear implants

Objective measurement of cochlear implant operation is described which coordinates the delivery to a patient of an acoustic signal and an electrical signal. The acoustic signal is developed as an acoustic stimulation input to the ear canal of a patient, and the electrical signal is developed as an electrical stimulation input to intracochlear electrodes of a cochlear implant. The evoked response in the patient to the delivered signals is then measured.
