对 40 名年龄和听力水平各异的受试者进行了安静、噪音和混响中元音识别的测试。刺激是在载体句子的 (b-t) 上下文中说出的 15 个英语元音，这些元音会因混响或噪音（12 个声音的胡言乱语）而被降级。元音识别分数与听力损失的各种测量值和年龄相关。 0.5、1、2 和 4 kHz 的四个听力级别的平均值（称为 HTL4）在所有三种听力条件下产生最高的相关系数。与年龄的相关性小于与 HTL4 的相关性，并且仅对于退化元音有意义。根据听力损失程度，对分配到四组的受试者进行了进一步分析。在噪音中，所有四组的表现都显着不同，而在安静和混响中，只有听力损失最严重的组的表现与其他组不同。根据可用于元音识别的声学线索，讨论了听力损失、年龄以及错误数量和类型之间的关系。
Vowel identification in quiet, noise, and reverberation was tested with 40 subjects who varied in age and hearing level. Stimuli were 15 English vowels spoken in a (b-t) context in a carrier sentence, which were degraded by reverberation or noise (a babble of 12 voices). Vowel identification scores were correlated with various measures of hearing loss and with age. The mean of four hearing levels at 0.5, 1, 2, and 4 kHz, termed HTL4, produced the highest correlation coefficients in all three listening conditions. The correlation with age was smaller than with HTL4 and significant only for the degraded vowels. Further analyses were performed for subjects assigned to four groups on the basis of the amount of hearing loss. In noise, performance of all four groups was significantly different, whereas, in both quiet and reverberation, only the group with the greatest hearing loss performed differently from the other groups. The relationship among hearing loss, age, and number and type of errors is discussed in light of acoustic cues available for vowel identification.
