Zur Wahrnehmung verhallter Sprache mit Cochleaimplantaten

Abstract

The results of the current investigation indicated that reverberation results in decreased speech understanding of CI users.

Impact of Reverberation on Speech Perception and Sound Localization Accuracy in Cochlear Implant Users With Single-Sided Deafness

“…It was also shown that late reflections mainly contributed to the decrease and that early reflections may not be detrimental to speech perception of CI users. Mühler and colleagues reported a significant decrease in speech perception scores in noise with increasing reverberation time in unilaterally tested CI users (co-located masker condition (29)). However, the results obtained are not comparable to the results of the presented study.…”

“…Sound localization was assessed in a virtual auditorium with a size of 22 m  16 m  10 m. The mean reverberation time was 0.51 seconds, based on the small reverberation time used by Kerber and Seeber in 2013, who found effects of reverberation on localization in bilateral CI users (28). Speech perception was assessed in a virtual auditorium with smaller dimensions (size: 16.0 m  12.0 m  7.4 m) and the mean reverberation time was 1.2 seconds, as Mu ¨hler and colleagues found in 2014 that higher reverberation times resulted in higher effects of reverberation on speech perception (29).…”

Binaural Sound Processing in Noise and Reverberation for Listeners with Cochlear Implants

“…Listeners with BCIs also demonstrated poorer speech understanding ability than listeners with NH in noise [4]. Regarding the reverberation effect, it was found that speech perception performance decreased as reverberation time increased and the performance started to be affected at 0.3-0.7 s reverberation time for listeners with unilateral cochlear implant (UCI) [7]. The adverse combined effect of noise and reverberation was found for listeners with UCI [8].…”
