Twenty-nine adult volunteers with stable bilateral sensorineural hearing loss were treated by acupuncture. Subjects were randomly assigned to one of four experimental groups: active needling, active needling followed by sham needling, sham needling followed by active needling, and sham needling. All subjects received 30 treatments. Only one ear was treated by acupuncture. The second ear was kept for an intrasubject control. Prior to treatment a baseline of hearing was established. During the course of acupuncture, audiological assessments (pure tone thresholds and speech tests) were made after sets of five treatments. Hearing was again measured during the year following acupuncture. The results in individual subjects and statistical comparisons of active and sham groups showed that acupuncture did not produce significant shifts in hearing.
29名患有稳定双侧感音神经性听力损失的成年志愿者接受了针灸治疗。受试者被随机分配到四个实验组之一：主动针刺组、先主动针刺后假针刺组、先假针刺后主动针刺组和假针刺组。所有受试者均接受30次治疗。仅对一只耳朵进行针灸治疗。另一只耳朵作为受试者自身对照。治疗前确定听力基线。在针灸过程中，每进行5次治疗后进行听力评估（纯音阈值和言语测试）。针灸后一年再次测量听力。个体受试者的结果以及主动针刺组和假针刺组的统计比较表明，针灸并未使听力产生显著变化。
