Listening effort during speech in noise recognition: a neurophysiologic evaluation of consecutive sound processors
The technological development in the cochlear implants (CI) has been producing external processors designed to increase performances in patients facing word in noise recognition conditions. In our study we investigated the neurophysiological responses underlying these abilities, firstly aiming at obtaining an electroencephalographic (EEG) measure of the listening effort experienced by patients. Secondly, we investigated whether the technological progress reduced such listening effort levels in these patients.
