The objective was investigating the effect of age on speech-in-noise perception (SINP) using word perception score in white noise (WPS in WN). This cross-sectional study was conducted on 76 participants, including 30 elderly (older than 61 years) and 46 young adults (between 14 and 35 years) with normal levels of stress, night sleep and mini-mental states. Audiological evaluations included acoustic immittance testing, pure tone audiometry, determination of speech reception threshold and WPS in WN. Data analysis were performed using Mann-Whitney and Tukey HSD tests. Based on the results of the tests, the participants were divided into three groups: (1) young adults with normal hearing (n = 30), (2) elderly adults with normal hearing (n = 16), (3) elderly adults with mild to moderate high frequency hearing loss (n = 14). In both groups of old adults, the means WPS in WN differences were significant only in the left ears (Pv = 0.008, 0.033, 0.025 for SNR = 0, +5, +10 dB). In the three groups and in the right ears, there were the significant differences between the means of WPS in WN (Pv = 0.002, 0.000, 0.001 for SNR = 0, +5, +10 dB), and also the left ears (Pv = 0.000, 0.002, 0.002 for SNR = 0,+5, +10 dB).There is a relationship between increasing age and decreasing WPS in WN. The deleterious effects of aging on SINP decline are greater than that of hearing loss.
目的是使用白噪声中的单词感知分数（WN中的WPS）来研究年龄对噪声中言语感知（SINP）的影响。这项横断面研究对76名参与者进行，包括30名老年人（61岁以上）和46名年轻人（14至35岁），他们的压力、夜间睡眠和简易精神状态水平正常。听力学评估包括声导抗测试、纯音听力测定、言语接受阈测定和WN中的WPS。使用Mann-Whitney和Tukey HSD检验进行数据分析。根据测试结果，参与者被分为三组：（1）听力正常的年轻人（n = 30），（2）听力正常的老年人（n = 16），（3）轻度至中度高频听力损失的老年人（n = 14）。在两组老年人中，WN中WPS的平均差异仅在左耳显著（SNR = 0、+5、+10 dB时，Pv分别为0.008、0.033、0.025）。在三组中以及右耳，WN中WPS的平均值之间存在显著差异（SNR = 0、+5、+10 dB时，Pv分别为0.002、0.000、0.001），左耳也是如此（SNR = 0、+5、+10 dB时，Pv分别为0.000、0.002、0.002）。年龄增长与WN中WPS降低之间存在关联。衰老对SINP下降的有害影响大于听力损失的影响。
