Characterization of Intrinsic Mode Functions of the Electrical Cochlear Response

Abstract

The aim of this paper was to characterize the Intrinsic Mode Functions (IMFs) of the Electrical Cochlear Response (ECR) obtained by Ensemble Empirical Mode Decomposition. Sample Entropy was used to identify the IMFs related to background noise, Cochlear Implant artefact, and ECR. Finally, Noise Reduction Percentage was used to quantify the decrease of artefact in the ECR reconstruction.
