Several studies in the literature suggest that poor health is related to hearing loss. One hundred subjects claiming occupational hearing loss were chosen randomly for this study. Information was obtained on employment, noise exposure, medical history, family history, and use of cigarettes, alcohol, and medication. Physical examination audiometric tests, and biological tests were carried out. Computer analysis of the data with chi-square test did not show conclusively that noise-induced hearing loss is related to poor health, indicated by abnormal biological or physical findings, or both. There were, however, some indications that the presence of cardiovascular risk factors may influence hearing loss.
文献中的几项研究表明，健康状况不佳与听力损失有关。本研究随机选取了100名声称有职业性听力损失的受试者。获取了有关就业、噪声暴露、病史、家族史以及香烟、酒精和药物使用情况的信息。进行了体格检查、听力测试和生物学测试。用卡方检验对数据进行计算机分析，并未确凿显示噪声性听力损失与健康状况不佳有关，健康状况不佳由生物学或体格检查异常结果或两者共同表明。然而，有一些迹象表明心血管危险因素的存在可能会影响听力损失。
