To describe the effect of age and noise on high frequency hearing thresholds in an Italian population aged 70 years and older, in order to investigate the interaction between presbycusis and noise exposure.
We compared 460 subjects: 367 affected by presbycusis alone (204 women and 163 men) and 93 affected by presbycusis and noise exposure (eight women and 85 men). Pure tone average hearing thresholds, for each ear, were compared between groups, and between sexes and ages within groups.
A slight threshold difference was found between the two groups at 4 kHz. After adjusting for age and gender, this difference was found to be related only to differing patient age. Men's and women's thresholds differed significantly in both groups, especially at high frequencies, at which threshold deterioration was worse in men than women.
The threshold differences between patients with presbycusis with and without noise exposure were limited. Larger studies are needed to assess the relative effects of ageing and noise exposure on hearing thresholds.
描述年龄和噪声对70岁及以上意大利人群高频听力阈值的影响，以研究老年性聋与噪声暴露之间的相互作用。
我们比较了460名受试者：367名仅患有老年性聋（204名女性和163名男性）和93名患有老年性聋且有噪声暴露（8名女性和85名男性）。比较了两组之间以及组内性别和年龄之间每只耳朵的纯音平均听力阈值。
在4kHz时两组之间发现了轻微的阈值差异。在调整年龄和性别后，发现这种差异仅与患者年龄不同有关。两组中男性和女性的阈值均有显著差异，尤其是在高频，此时男性的阈值恶化比女性更严重。
有噪声暴露和无噪声暴露的老年性聋患者之间的阈值差异有限。需要进行更大规模的研究来评估衰老和噪声暴露对听力阈值的相对影响。
