Abstract
In this study the effects of presentation level and signal-to-noise ratio on phonemic confusions are investigated in 25 hearing-impaired subjects. The confusions of initial consonants, vowels and final consonants in the perception of nonsense CVC words were determined at three presentation levels in quiet and three signal-to-noise ratios in noise. The group results of the different presentation conditions were analyzed by means of INDSCAL analyses. The presence or absence of interfering noise proved to be the most dominant factor: the presence of noise caused a reduced use of low-frequency information. The effects of presentation level are of secondary importance. Dans cette étude les effets du niveau de présentation et du rapport signal/bruit sur les confusions phonémiques on été étudiés chez 25 sujets sourds. Les confusions des consonnes initiales, des voyelles et des consonnes finales dans la perception de mots CVC sans signification ont été déterminées à trois niveaux de présentation dans le silence et pour trois rapports signal/bruit. Les résultats groupés des différentes conditions de présentation ont été analysés au moyen de INDSCAL. La présence ou l'absence de bruit s'est révélée ětre le facteur dominant: la présence de bruit a entraiˇne une réduction de l'utilisation de l'information basse fréquence. Les effets du niveau de présentation sont d'importance secondare.Keywords
