Assess the impact of a reduction of tinnitus intensity achieved through sound stimulation during sleep on the improvement in the patients' quality of life.
Acoustic stimuli consisted of a highly customized sound that reproduced the spectral and intensity characteristics of the tinnitus in each patient. This stimulus was uploaded into a portable electronic device and delivered through customized ear buds during sleep, every night for three months.
Twelve patients with subjective idiopathic chronic tinnitus were studied.
Results were assessed through: (1) the measurement in dB SPL of tinnitus intensity reduction over time; (2) the results of three psychometric tests: Tinnitus handicap inventory (THI), Tinnitus reaction questionnaire (TRQ), Tinnitus functional index (TFI); and (3) a Visual analog scale (VAS) for tinnitus annoyance. After three months of treatment, we observed an average decrease in tinnitus intensity of 14.1 dB SPL (p < 0.001), implying a 62% reduction of the perceived sound. This improvement was followed by a statistically significant decrease of TRQ (78%), THI (65%), and TFI (77%).
These results suggested that the intensity reduction achieved through the protocol used in this study had a direct impact on the improvement in the patients' quality of life.
评估睡眠期间通过声音刺激降低耳鸣强度对患者生活质量改善的影响。
声学刺激由高度定制的声音组成，该声音再现了每位患者耳鸣的频谱和强度特征。此刺激被上传到便携式电子设备中，并在睡眠期间通过定制的耳塞每晚播放，持续三个月。
对12例主观性特发性慢性耳鸣患者进行了研究。
通过以下方式评估结果：（1）随时间测量耳鸣强度降低的分贝声压级（dB SPL）；（2）三项心理测量测试的结果：耳鸣障碍量表（THI）、耳鸣反应问卷（TRQ）、耳鸣功能指数（TFI）；以及（3）耳鸣烦恼视觉模拟量表（VAS）。治疗三个月后，我们观察到耳鸣强度平均降低了14.1 dB SPL（p < 0.001），这意味着感知到的声音降低了62%。这种改善之后，TRQ（78%）、THI（65%）和TFI（77%）在统计学上显著下降。
这些结果表明，通过本研究中使用的方案实现的强度降低对患者生活质量的改善有直接影响。
