A new adaptive technique of estimation of steady state auditory evoked potentials

A novel technique of fast estimation of steady state auditory evoked potentials (SSAEPs) for rapid assessment of the functionality of the human auditory nervous system is presented. The proposed SSAEP signal estimation is based on a new nonlinear adaptive signal processing method that has shown a great promise in the fast extraction of weak signals buried under large amounts of noise. Currently, the main technical impediment in the widespread clinical use of the SSAEP testing for hearing assessment is the excessively long measurement time needed for the estimation process due to the presence of large amounts of background noise. The studies in this paper show significant reduction in the measurement time achieved by the proposed technique.
