This study investigated whether unique consonant recognition and confusion patterns are associated with hearing loss among elderly listeners. Subjects were all greater than 65 years, and had normal hearing, or gradually or sharply sloping sensorineural hearing losses. Recognition of 19 consonants, paired with each of three vowels in a CV format, was assessed at two speech levels in a background of babble (+6 dB signal-to-babble ratio). Analyses of percent correct scores for overall nonsense syllable performance and for consonants according to place, manner, and voicing categories generally revealed better performance by the normal-hearing subjects than by the hearing-impaired subjects. However, individual differences scaling analysis of consonant confusions failed to retrieve speech perception patterns that were unique to listener group. These results tentatively suggest that the presence and configuration of hearing loss among elderly listeners may affect the level of performance but not the specific pattern of performance.
本研究调查了老年听众独特的辅音识别和混淆模式是否与听力损失有关。受试者均年龄大于65岁，听力正常，或患有逐渐或急剧下降的感音神经性听力损失。在嘈杂背景（信号与嘈杂声之比为+6 dB）下的两个言语水平上，评估了以CV形式与三个元音之一配对的19个辅音的识别情况。对整体无意义音节表现以及根据发音部位、发音方式和浊音类别划分的辅音的正确得分百分比进行分析，结果普遍显示，听力正常的受试者比听力受损的受试者表现更好。然而，辅音混淆的个体差异标度分析未能找出听众群体特有的言语感知模式。这些结果初步表明，老年听众听力损失的存在和形态可能会影响表现水平，但不会影响表现的具体模式。
