A group of 40 elderly subjects were evaluated using a variety of audiological tests. Their mean age was 68 years. They had all come to the clinic because of hearing problems. The subjects were selected for this study because no cause of their hearing loss could be found other than presbycusis. They all had the typical moderately sloping pure tone audiogram configuration. The pure tone average hearing loss (PTA, average of 0.5, 1 and 2 kHz) ranged from 11 to 70 dBHL with a median of 40. The average air-bone gap was 3 dB. In addition to pure tone audiometry the following tests were performed: most comfortable loudness level and uncomfortable loudness level for pure tone; stapedius reflex thresholds; speech recognition threshold and maximum speech recognition score in quiet; distorted speech recognition; detection thresholds for frequency and intensity glides of a pure tone; slow evoked cortical potentials in response to frequency and intensity glides of a pure tone. The test results, when compared with those obtained on young subjects with normal hearing and with cochlear lesions, show a mixture of characteristics typical of cochlear, retrocochlear and central lesions.
一组40名老年受试者接受了多种听力学测试评估。他们的平均年龄为68岁。他们都是因为听力问题前来诊所的。选择这些受试者进行这项研究是因为除了老年性耳聋外，未发现其他导致他们听力损失的原因。他们都具有典型的中度倾斜纯音听力图构型。纯音平均听力损失（PTA，0.5、1和2千赫兹的平均值）范围为11至70分贝听力级，中位数为40。平均气骨导间距为3分贝。除了纯音听力测定外，还进行了以下测试：纯音的最舒适响度级和不舒适响度级；镫骨肌反射阈值；安静环境下的言语识别阈值和最大言语识别得分；畸变言语识别；纯音频率和强度渐变的检测阈值；对纯音频率和强度渐变的慢诱发电位皮层电位。与听力正常的年轻受试者和耳蜗病变受试者的测试结果相比，这些测试结果显示出耳蜗、蜗后和中枢病变典型特征的混合。
