Fitting System Based on Base-Etation and Fitting Software for Fully Implantable Middle Hearing Device

We announced that fully implantable middle ear hearing device (F-IMEHD) has been researched in several papers. The F-IMEHD requires proper fitting process reflected properties of each device like other hearing aids. The F-IMEHD uses vibration transducer attached on ossicles for a sound transmission to human´s inner ear. The F-IMEHD is implanted under the skin. Therefore, the fitting process for F-IMEHD has to consider properties of the microphone and transducer. In this paper, fitting system which consist of basestation and fitting software, have been designed and implemented for fitting and control of F-IMEHD. We calculate proper parameters according to hearing threshold level of each patient using the fitting software, and the parameters are transmitted to implanted system from the base-station. The base-station has all control function for F-IMEHD using a wireless communication. Moreover the base-station is a relay station which fitting parameters send to implanted system from fitting software on a PC.
