PhD degree successfully defended by Gusztáv Lőcsei

On Nov 15, Gusztáv Lőcsei successfully defended his PhD thesis titled "Lateralized speech perception with normal and impaired hearing".

Listeners with sensorineural hearing impairment often report difficulties with speech communication, predominantly in acoustic environments with multiple, spatially distributed interferers. Unfortunately, amplification which compensates for elevated hearing thresholds does not typically necessarily resolve these problems. In his thesis, Gusztáv Lőcsei explored potential links between temporal fine structure (TFS) coding abilities and binaural unmasking (BU) of speech in a variety of lateralized listening scenarios. His findings contribute to our understanding of how supra-threshold deficits affect speech intelligibility in complex acoustic scenarios, and underline the role of robust binaural TFS coding in the facilitation of BU. Overall, hearing-impaired listeners exhibited near-to-normal spatial release from masking. Thus, the problems they experience in complex acoustical environments are likely due to monaural rather than binaural processing deficits.
