This study was designed to determine whether extended high-frequency audiometry was capable of better differentiating between participants with normal hearing who did or did not have subjective tinnitus.
A total of 96 study participants were enrolled: 36 patients with unilateral tinnitus, 28 patients with bilateral tinnitus and 32 volunteers as controls. All 96 participants exhibited normal audiometry findings and hearing thresholds. Extended high-frequency audiometry was used to evaluate these patients.
There were differences between the extended high-frequency hearing thresholds of affected and unaffected ears in those with unilateral tinnitus, and in the 20-29-year-old bilateral tinnitus group, at 11.2, 12.5 and 14 kHz. Unilateral tinnitus subgroups had higher extended high-frequency hearing thresholds than those in control subjects, at all extended high frequencies.
Extended high-frequency audiometry can offer additional information regarding the hearing status of patients with tinnitus who exhibit normal pure tone thresholds when analysed via conventional hearing thresholds.
本研究旨在确定扩展高频测听法是否能够更好地区分听力正常但有或无主观性耳鸣的参与者。
共招募了96名研究参与者：36名单侧耳鸣患者、28名双侧耳鸣患者和32名志愿者作为对照。所有96名参与者的听力测定结果和听力阈值均正常。采用扩展高频测听法对这些患者进行评估。
单侧耳鸣患者患侧和未患侧耳朵的扩展高频听力阈值之间存在差异，在20 - 29岁的双侧耳鸣组中，在11.2、12.5和14千赫时也存在差异。单侧耳鸣亚组在所有扩展高频下的扩展高频听力阈值均高于对照组。
当通过传统听力阈值分析时，扩展高频测听法可为耳鸣患者的听力状况提供额外信息，这些患者的纯音阈值正常。
