PURPOSE To study the perceptual consequences of changes in parameters of vocoded speech in various reverberation conditions. METHOD The 3 controlled variables were number of vocoder bands, instantaneous frequency change rate, and reverberation conditions. The effects were quantified in terms of (a) nonsense words' recognition scores for young(More)
This study assessed the effects of speech misidentification and cognitive processing errors in normal-hearing adults listening to degraded auditory input signals simulating cochlear implants in reverberation conditions. Three variables were controlled: number of vocoder channels (six and twelve), instantaneous frequency change rate (none, 50, 400 Hz), and(More)
BACKGROUND An important negative factor of EVAR is the radiation acquired during long-lasting procedures. The aim of the study was to document the radiation doses of EVAR and to discuss potential reasons for prolongation of radiological procedures. MATERIAL/METHODS Dose-area product (DAP) (Gy cm²) and air kerma (AK) (Gy) obtained during EVAR from 92(More)
