Audiometric data are presented from a cross sectional and longitudinal population study of 70 and 75 year old people in Gothenburg, Sweden. The population studied included 1148 randomly selected 70 year old men and women. A subsample of 376 was tested with pure tone and speech audiometry. Five years later 261 of those were tested again with the same methods. The mean pure tone thresholds were only 8 to 10 dB. higher than data chosen as representative for presbycusis in selected populations. Between the ages of 70 and 75 there was no detectable change in the pure tone thresholds for men. The hearing threshold in women had deteriorated throughout the entire frequency range and most were at 4 and 8 kHz. Speech discrimination scores were unexpectedly high. Seventy-five per cent of the women and 50 per cent of the men had discrimination scores equal to or better than 92 per cent at the age of 70. At the age of 75 about 65 per cent of the women and 35 per cent of the men had the same excellent speech discrimination
听力测定数据来自瑞典哥德堡对70岁和75岁人群的横断面和纵向研究。研究对象包括1148名随机抽取的70岁男性和女性。对376人的一个子样本进行了纯音和言语听力测定测试。五年后，其中261人再次用相同方法进行了测试。平均纯音听阈仅比选定人群中作为老年性聋代表的数据高8至10分贝。70至75岁之间，男性的纯音听阈没有可检测到的变化。女性的听力阈值在整个频率范围内都有所恶化，大多数在4千赫和8千赫处。言语辨别分数出乎意料地高。75%的女性和50%的男性在70岁时辨别分数等于或优于92%。在75岁时，约65%的女性和35%的男性有同样出色的言语辨别能力
