Silvio P. Eberhardt is a Research Associate Professor in the Department of Speech, Language and Hearing Science. As a member of the Communication Neuroscience Laboratory he is involved with research on multisensory perception and lipreading using behavioral and electroencephalography (EEG) neuroimaging techniques. He has developed the lab’s custom and fully-automated systems for carrying out behavioral and EEG studies and reformatting the resulting data for analysis and graphical display. He has previously taught engineering and computer science courses at Swarthmore College and Villanova University, and has co-founded several engineering design companies. He is the inventor or co-inventor on ten U.S. Patents.

The Communication Neuroscience Laboratory carries out fundamental and applied research on the perceptual, cognitive and neural bases for speech perception and spoken word recognition. Current research areas include tactile perception of speech, development of perceptual training methods to improve speech-in-noise perception by individuals with hearing loss, and exploring why some individuals have trouble understanding speech in noisy environments despite having normal peripheral hearing.
