The purpose of the study was to examine the test-retest value of tinnitus pitch and loudness in patients with tinnitus and noise-induced hearing loss (NIHL).
The study sample consisted of 30 patients of mean age 35 +/- 6.7 years with long-standing tinnitus and hearing loss due to exposure to noise during military service. Ten patients had unilateral tinnitus, and 20 had bilateral tinnitus. All presented with a typical NIHL audiogram on the affected side(s). None of the patients was receiving drug therapy.
There was no statistically significant difference in tinnitus pitch or loudness between the 2 tests for the whole group and separately in patients with unilateral or bilateral tinnitus.
Subjective testing of pitch and loudness of tinnitus secondary to NIHL is accurate and reproducible, making it a valuable tool for diagnosis and follow-up. The lack of differences between patients with unilateral or bilateral tinnitus indicates that both types may be managed in a similar manner.
本研究旨在探讨耳鸣音调与响度的复测值在耳鸣伴噪声性听力损失（NIHL）患者中的意义。
研究对象为 30 名平均年龄为 35 +/- 6.7 岁的患者，他们均因在军队服役期间暴露于噪声而导致长期耳鸣和听力损失。10 名患者为单侧耳鸣，20 名患者为双侧耳鸣。所有患者的患侧均呈现典型的 NIHL 听力图。所有患者均未接受药物治疗。
对于整个组以及单侧或双侧耳鸣患者，两次测试的耳鸣音调或响度均无统计学差异。
NIHL 引起的耳鸣音调与响度的主观测试准确且可重复，是一种有价值的诊断和随访工具。单侧或双侧耳鸣患者之间无差异表明这两种类型可能以相似的方式进行管理。
