Consonant perception was investigated for 120 normal-hearing adults who listened to 16 consonants in a phrase context and made similarity judgements of 256 diadic stimulus pairs on a 9-point equal-appearing interval scale. Stimuli were presented at subjects' most comfortable listening levels in 3 low-pass filtered and one nonfiltered conditions. Subjects' ratings were converted to 16 X 16 full symmetric similarity matrices and submitted to INDSCAL analyses. Results revealed perceptual features common to all groups, as well as group-specific features (i.e., sibilancy, stop/continuancy, and place for nonfiltered; plosive and place for 4000-Hz low-pass; stop/continuancy and place for 2000-Hz low-pass; and voicing and stop/continuancy for 500-Hz low-pass). These results were similar to those found earlier for hearing-impaired subjects having sensorineural losses compatible with these frequency cut-offs.
对120名听力正常的成年人进行了辅音感知研究，这些成年人在短语情境中听16个辅音，并在9点等距量表上对256对二元刺激对进行相似性判断。在3种低通滤波条件和1种未滤波条件下，以受试者最舒适的聆听水平呈现刺激。受试者的评分被转换为16×16的完全对称相似性矩阵，并进行INDSCAL分析。结果揭示了所有组共有的感知特征，以及特定组的特征（即，未滤波时的咝音、塞音/延续音和发音部位；4000赫兹低通时的爆破音和发音部位；2000赫兹低通时的塞音/延续音和发音部位；以及500赫兹低通时的浊音和塞音/延续音）。这些结果与早期对患有与这些频率截止值相符的感音神经性听力损失的听力受损受试者的研究结果相似。
