Current Research

Martin Lindenbeck investigates selective hearing in cochlear-implant (CI) listeners. These hearing prostheses are currently the most successful treatment for severe hearing loss or deafness.

Despite substantial successes in speech perception in quiet since the early 1990s, there are still substantial deficits in so-called electric hearing, especially in spatial hearing and pitch perception. CI listeners thus have major problems with speech intelligibility with background noise or melody perception. Within the ITD PsyPhy project, an improvement of directional coding (interaural time differences, ITD) in pseudo-syllabic signals in electric hearing with modified pulse trains is investigated. Since ITDs and pitch are coded in similar parts of the acoustic signal, in his master's thesis and also within the ITD PsyPhy project Martin Lindenbeck investigated to what extent these new signals further affect pitch perception.

In principle, pitch can be perceived when stimulating with only one of the roughly dozen electrodes usually available. For selective hearing, however, more than one stimulating electrode is required, ideally as many as possible. In his doctoral thesis, Martin Lindenbeck is investigating the effects of the interaction of several stimulating electrodes on selective hearing, in particular ITD and pitch perception as well as speech understanding. To conduct this work, he received a two-year DOC Fellowship from the Austrian Academy of Sciences.
