本研究的目的是描述 55 至 65 岁健康、耳科筛查人群中特定听力图配置的流行情况。通过人口登记处收集了 1147 名受试者（549 名男性和 598 名女性，年龄在 55 至 65 岁之间）的听力图，并根据听力损失的配置进行分类。通过统计确定性别和噪声/溶剂暴露对不同听力图形状患病率的影响。在我们的人群中，“平坦”听力图占主导地位（37%），其次是“高频缓倾斜”听力图（35%）和“高频陡倾斜”听力图（27%）。 “低频上升”听力图、“中频 U 形”听力图和“中频反 U 形”听力图非常罕见（总共不到 1%）。 “平坦”配置在女性中更为常见，而“高频陡坡”配置在男性中更常见。暴露于噪音和/或溶剂中并没有改变这一发现。此外，与男性相比，听力图“平坦”的女性总体听力损失明显更大。此外，我们的数据揭示了“高频陡坡”听力图的患病率与噪声/溶剂暴露程度之间存在显着关联，尽管非暴露对象中相对较高比例也显示“高频陡坡”听力图。
The aim of this study was to describe the prevalence of specific audiogram configurations in a healthy, otologically screened population between 55 and 65 years old. The audiograms of 1147 subjects (549 males and 598 females between 55 and 65 years old) were collected through population registries and classified according to the configuration of hearing loss. Gender and noise/solvent-exposure effects on the prevalence of the different audiogram shapes were determined statistically. In our population 'Flat' audiograms were most dominantly represented (37%) followed by 'High frequency Gently sloping' audiograms (35%) and 'High frequency Steeply sloping' audiograms (27%). 'Low frequency Ascending' audiograms, 'Mid frequency U-shape' audiograms and 'Mid frequency Reverse U-shape' audiograms were very rare (together less than 1%). The 'Flat'-configuration was significantly more common in females, whereas the 'High frequency Steeply sloping'-configuration was more common in males. Exposure to noise and/or solvents did not change this finding. In addition, females with a 'Flat' audiogram had a significantly larger amount of overall hearing loss compared to males. Furthermore, our data reveal a significant association between the prevalence of 'High frequency Steeply sloping' audiograms and the degree of noise/solvent exposure, despite a relatively high proportion of non-exposed subjects showing a 'High frequency Steeply sloping' audiogram as well.
