This Cochrane Corner features "Sound therapy (using amplification devices or sound generators) for tinnitus" published in 2018. Sereda et al. identified eight clinical trials including 590 participants receiving sound therapy for tinnitus. None of the included studies addressed three main comparisons of the review (comparing hearing aids, sound generators and combination devices with a waiting list control group, placebo or education/information only). One study compared patients fitted with sound generators versus those fitted with hearing aids and found no difference between them in their effects on tinnitus symptom severity. The use of both types of device was associated with a clinically significant reduction in tinnitus symptom severity. Three studies compared hearing aids with a sound generator to hearing aids alone and measured tinnitus symptom severity. The use of both types of device was again associated with a clinically significant reduction in tinnitus symptom severity. This Cochrane review shows that both hearing aids and sound generators may be beneficial for reducing tinnitus severity in some patients, but that there is insufficient evidence at this stage to recommend one device over another, or whether these devices offer any improvement over a placebo treatment.
这篇 Cochrane Corner 特写介绍了 2018 年发表的“声音疗法（使用放大设备或声音发生器）治疗耳鸣”。Sereda 等人确定了八项临床试验，包括 590 名接受耳鸣声音疗法的参与者。纳入的研究均未解决综述的三个主要比较（比较助听器、声音发生器和组合设备与等待名单对照组、安慰剂或仅教育/信息）。一项研究比较了安装声音发生器的患者与安装助听器的患者，发现它们在耳鸣症状严重程度方面没有差异。两种类型的设备的使用都与耳鸣症状严重程度的临床显著降低相关。三项研究将助听器与声音发生器进行了比较，结果发现与单独使用助听器相比，这两种设备都能显著降低耳鸣症状的严重程度。这项 Cochrane 综述表明，助听器和声音发生器可能对一些患者减轻耳鸣严重程度都有益，但现阶段还没有足够的证据推荐一种设备优于另一种，也没有证据表明这些设备比安慰剂治疗有任何改善。
