Clinically, we find that tinnitus patients often have hearing loss. According to the most accepted mechanism of tinnitus, that is, the spontaneous discharge and abnormal synchronization of neurons after afferent reduction, tinnitus frequency is closely related to the frequency of hearing loss.
The purpose of this study was to investigate the correlation of tinnitus pitch with the frequency of hearing loss.
A total of 500 patients with unilateral or bilateral chronic tinnitus were enrolled in this study. All patients underwent pure tone audiometry (PTA) and tinnitus acoustic examination. Hearing loss levels and frequencies were recorded. The relationship between tinnitus pitch and hearing loss level and frequency was statistically analyzed.
Our results showed that 96.6% of the 500 tinnitus patients had hearing loss. Statistical analysis showed that low frequency (LF) tinnitus was correlated with LF hearing loss, but moderate frequency & high frequency (MF&HF) tinnitus was not significantly associated with MF&HF hearing loss. The coincidence of tinnitus pitch with the highest hearing threshold correlated with the degree of hearing loss.
The vast majority of patients with chronic subjective tinnitus had hearing loss, and the frequency of tinnitus correlated with the degree and frequency of hearing loss but not exactly fall within the frequency range of hearing loss.
临床上，我们发现耳鸣患者常伴有听力损失。根据耳鸣最被接受的机制，即传入减少后神经元的自发性放电和异常同步，耳鸣频率与听力损失的频率密切相关。
本研究旨在探讨耳鸣音调与听力损失频率的相关性。
共纳入 500 例单侧或双侧慢性耳鸣患者。所有患者均行纯音听阈测试（PTA）和耳鸣声学检查。记录听力损失水平和频率。对耳鸣音调与听力损失水平和频率的关系进行统计学分析。
我们的结果显示，500 例耳鸣患者中有 96.6%存在听力损失。统计分析表明，低频（LF）耳鸣与 LF 听力损失相关，而中频和高频（MF&HF）耳鸣与 MF&HF 听力损失无显著相关性。耳鸣音调与最高听阈的吻合程度与听力损失程度相关。
绝大多数慢性主观性耳鸣患者存在听力损失，耳鸣频率与听力损失程度和频率相关，但并不完全落在听力损失频率范围内。
