Abstract

Theta and Alpha EEG rhythms appear useful for the listening effort estimation. In particular, Alpha would inhibit irrelevant stimuli, and Theta underlies working memory and processing. The balance between them seems essential for the word recognition, therefore evaluating the listening effort experienced by hearing impaired patients appears worthy, since noise/distortions in a speech signal increase listening effort. Aim of the study was the estimation of the effort during word in noise recognition under different noise conditions, and along the task. Results showed an increase in the frontal Theta and parietal Alpha for a difficult (but not the most difficult) noise condition, and for Theta in correspondence of the stimulus. Additionally, frontal Theta activity increased along the task for the same difficult noise condition during and after the stimulus. This evaluation was preliminary for a neurofeedback application of the effort management by CI users, since it could affect performances and attitudes. Such assessment appears extremely worthy of investigation since the symbiotic interaction between cochlear implant devices and deaf patients for the decoding and processing of the incoming auditory signal.
