Introduction Hypertension (HTN) is a common health problem, diagnosed in every one out of four individuals. It is associated with various complications; however, its impact on hearing loss is not well studied. In this study, we will determine the impact of HTN on hearing. Methods This cross-sectional study was conducted in Jinnah Sindh Medical University from August 2020 to March 2021. Three hundred (300) patients with documented diagnosis of HTN, between the ages of 21 and 50 years, were enrolled in the study. Another 300 non-hypertensive participants were enrolled as a reference group. Participants were sent to trained otolaryngologist technicians, who performed audiometry at six different frequencies for each year (0.5, 1.0, 2.0, 3.0, 4.0, and 6.0 kilohertz (kHz)). The final hearing level was calculated by taking mean of hearing levels of both ears. Results The hearing levels in audiometry were significantly higher in hypertensive participants compared to non-hypertensive participants (23.4 ± 8.67 dB vs 18.3 ± 6.02 dB; p-value: <0.0001). Participants who had been diagnosed with HTN for more than five years had higher hearing levels in audiometry test compared to participants with less than five years of HTN (24.21 ± 8.92 dB vs. 22.6 ± 8.02 dB; p-value 0.0001). Conclusion Based on our study, HTN is positively correlated with hearing loss. Therefore, longstanding hypertensive patients should be screened regularly in order to assess the status of their hearing abilities.
引言
高血压（HTN）是一个常见的健康问题，每四个人中就有一人被诊断患有此病。它与多种并发症相关；然而，其对听力损失的影响尚未得到充分研究。在本研究中，我们将确定高血压对听力的影响。
方法
本横断面研究于2020年8月至2021年3月在真纳信德医科大学进行。研究纳入了300名年龄在21至50岁之间、有高血压确诊记录的患者。另外300名非高血压参与者作为参照组。参与者被送至训练有素的耳鼻喉科技术人员处，这些技术人员每年在六个不同频率（0.5、1.0、2.0、3.0、4.0和6.0千赫兹（kHz））进行听力测定。最终听力水平通过计算双耳听力水平的平均值得出。
结果
与非高血压参与者相比，高血压参与者的听力测定听力水平显著更高（23.4±8.67分贝对18.3±6.02分贝；p值：<0.0001）。与高血压病程少于五年的参与者相比，被诊断患有高血压超过五年的参与者在听力测定测试中的听力水平更高（24.21±8.92分贝对22.6±8.02分贝；p值0.0001）。
结论
基于我们的研究，高血压与听力损失呈正相关。因此，长期高血压患者应定期进行筛查，以评估其听力状况。
