Abstract:
Cochlear implants are neuro-stimulating devices helping severely deaf people to perceive sounds. This work proposes two models for the optimization of electrodes array stimulation in cochlear implants. The first model was developed according to wave propagation theory applied to the cochlea. The second one consisted on data processing using a Short Time Fourier Transform (STFT) in order to remedy to the first model limitations. The models were tested with an acoustic signal, which frequency belongs to the human hearing frequency range. Frequency and transient representations of the reconstructed signals were compared, emphasizing the better linearity of the STFT model.
