    摘要： Methods and systems for normalizing a spectral profile corresponding to an audio signal include detecting a spectral profile of an incoming audio signal and comparing the spectral profile of the incoming audio signal to a reference spectral profile. The methods further include using the comparison to determine an adjusted spectral profile that more closely matches the reference spectral profile than does the spectral profile of the incoming audio signal and applying electrical stimulation representative of the adjusted spectral profile to a cochlear implant patient.
