Abstract
-
The effect of reverberation on the phoneme discrimination ability of normal-hearing children, aged 5, 7, 9, 11, and 13, and a group of adults was determined by measuring discrimination of 114 VCV nonsense disyllables under three conditions of reverberation (0, 0.4, and 0.6-sec reverberation times). Experimental recordings were made through KEMAR and an associated Killion filter in an anechoic room and in a reverberation room. Testing was done via headphones in the binaural mode (non-reverberant, 0.4, and 0.6-sec condition) and the monaural mode (0.6-sec condition).;Analysis of variance techniques were used to determine the contribution of the factors of age and reverberation and of age and mode of presentation. Confusion matrices were also analyzed to determine patterns of errors for the children and adults.;The analyses revealed that the 0.4 and 0.6-sec reverberation times caused significant decreases in phoneme discrimination of all subjects.;Phoneme discrimination scores for the reverberant conditions improved with increasing age. Age differences were statistically significant.;Binaural listening was superior to monaural listening for all age groups. The monaural/binaural difference was statistically significant.;The pattern of phoneme errors obtained in the reverberant conditions was similar to that reported by other investigators. Place and manner errors were most common, while voicing and nasality errors were rare. The majority of the manner errors involved confusions between stops and fricatives.;In general, the children made the same type of errors as the adults, but made more errors. However, the younger children (5, 7, and 9-year-olds) did make some substitutions which differed from those of older children and adults. These errors included the features of voicing, affrication, and the consonantal feature.
