1. A calibration method including establishing a calibration mapping for calibrating a hearing system comprising a cochlea implant having a lead including an electrode array and a plurality of sensors configured to sense vibrations of the basilar membrane while in an implanted state, the calibration method comprising:
providing acoustic stimulation in the ear canal with an acoustic test signal with known spectrum, where after the middle ear converts the acoustic test sound to mechanical excitation of the basilar membrane, which responds with motion that performs a frequency-to-place conversion, measuring, via the sensor in the cochlea implant, the excitation pattern of the basilar membrane, comparing the measured excitation pattern of the basilar membrane with an expected excitation pattern based on the acoustic test signal, and establishing the calibration mapping by assigning characteristic frequencies to the excitated positions and the electrode array.
