Abstract

Introduction: We aimed to investigate the clinical significance of the loudness discomfort level (LDL) test in tinnitus patients and its relationship with pure-tone audiometry, tinnitogram, and questionnaires.

Methods: We retrospectively reviewed the medical records of 320 tinnitus patients who visited a tertiary university hospital's tinnitus clinic and completed LDL tests between March 2020 and December 2022. Epidemiological data and psychoacoustic test results were collected.

Results: The LDL showed no significant differences between frequencies for both ears. The mean LDL did not correlate with mean pure-tone average or hearing thresholds at each frequency. The hearing loss group had a higher LDL at 8 kHz compared to the normal hearing group (p < 0.01). Objective sound intolerance was found in a quarter, correlating with subjective hyperacusis, anxiety, and depression. Weak negative correlations were found between most of questionnaire's scores and LDL on the left side. Tinnitus loudness weak negatively correlated with LDL at most frequencies, except 8 kHz.

Discussion/conclusion: Our findings suggest a notable association between LDL levels and emotional factors in tinnitus patients, rather than with auditory thresholds. While lateralized differences in LDL responses were observed, specifically on the left side, these preliminary results do not confirm a causal link and thus do not warrant changes to current clinical testing protocols without further research.

耳鸣患者的响度不舒适度测试分析
简介:我们旨在研究耳鸣患者响度不适水平(LDL)测试的临床意义及其与纯音测听、耳鸣图和问卷调查的关系:我们旨在研究耳鸣患者响度不适水平(LDL)测试的临床意义及其与纯音测听、耳鸣图和问卷调查的关系:我们回顾性地查阅了 320 名耳鸣患者的病历,这些患者于 2020 年 3 月至 2022 年 12 月期间在一家三级甲等大学医院耳鸣门诊就诊并完成了 LDL 测试。收集了流行病学数据和心理声学测试结果:双耳的 LDL 在不同频率之间无明显差异。平均 LDL 与各频率的平均纯音平均值或听阈没有相关性。与听力正常组相比,听力损失组在 8 kHz 时的 LDL 较高(讨论/结论:我们的研究结果表明,耳鸣患者的低密度脂蛋白水平与情绪因素而非听阈之间存在显著关联。虽然观察到低密度脂蛋白反应的侧向差异,特别是左侧,但这些初步结果并不能证实两者之间存在因果关系,因此在没有进一步研究的情况下,没有必要改变目前的临床测试方案。

期刊介绍: ''Audiology and Neurotology'' provides a forum for the publication of the most-advanced and rigorous scientific research related to the basic science and clinical aspects of the auditory and vestibular system and diseases of the ear. This journal seeks submission of cutting edge research opening up new and innovative fields of study that may improve our understanding and treatment of patients with disorders of the auditory and vestibular systems, their central connections and their perception in the central nervous system. In addition to original papers the journal also offers invited review articles on current topics written by leading experts in the field. The journal is of primary importance for all scientists and practitioners interested in audiology, otology and neurotology, auditory neurosciences and related disciplines.
