Abstract

Implantable hearing prostheses, especially of the type that electrically stimulate neural centers within the cochlear, incorporate complex signal processing and delivery systems that must be customized to suit the differing and individual needs of each user before the full and safe benefit of the prosthesis can be realized.

Title 

Cochlear implant self fitting system

Problem Addressed

Implantable hearing prostheses, especially of the type that electrically stimulate neural centers within the cochlear, incorporate complex signal processing and delivery systems that must be customized to suit the differing and individual needs of each user before the full and safe benefit of the prosthesis can be realized.

The customization or fitting of current art prostheses is performed by health care professionals, using specialized equipment in a sound proofed room at a hearing clinic. There, in some cases, more than fifty different operating parameters are set or optimized on the basis of trial and error adjustments guided by vocal and or neural feedback from the user.

Acute post-operative and long-term biological changes in the recipient usually necessitate several clinic-hosted adjustment sessions during the first year or two of implantation. Such fitting sessions are not only inconvenient and costly for the recipient, but they also place a high demand on the often scant resources of the health care sector.

A more efficient and cost effective method is needed to properly fit cochlear implants to an individual so that they may receive the maximum benefit from their prosthesis.

Novelty Statement

The disclosed invention is for a self-fitting system which allows the user of a hearing prosthesis to interactively adjust the operating parameters of their hearing prosthesis in the comfort of their home, so as to optimize, or at least improve, their hearing experience. This self-fitting system consists of a specific program of interactive audio and visual material recorded on a digital video disk (DVD) for replay on a domestic television.

Description (Components, Process)

This invention can help alleviate much of these costs and the inconvenience by allowing many, if not most, implantable hearing prosthesis users to interactively optimize the operation of their hearing prosthesis themselves, in the comfort of their home, at any time they wish. This is especially beneficial to cochlea implant users as they are normally required to regularly attend special hearing clinics for acoustic testing and adjustment of around 50 different personalized operating parameters of their prosthesis.

The invention facilitates "self-fitting" by presenting special sequences of pre-recorded audio and video program material that instruct a user and control the behavior of their prosthesis in order to execute various self-fitting software routines stored in the memory of the prosthesis. Interactive feedback is captured from the user by way of:

·         A variety of user-operated controls associated with their prosthesis and,

·         The device that is replaying pre-recorded sequences of the self-fitting program.
