Hearing aids with an integrated sound generator have been used to enhance the treatment of tinnitus. The main aim of this study was to verify whether the combined use of amplification and sound generator is more effective than conventional amplification alone in reducing tinnitus annoyance by means of the use of a new hearing aid with an integrated sound generator. A total of 49 patients underwent a blind randomized clinical trial. Tinnitus annoyance was measured by Tinnitus Handicap Inventory and numerical scales, and psychoacoustic measures of tinnitus were also performed. The sound generator was set at the lowest intensity capable of providing relief from tinnitus. Results showed that 62.5% of the patients presented a reduction in tinnitus annoyance in the combined fitting group and in the group with amplification alone, 78% showed a reduction. This difference between the groups was not statistically significant.
带有集成声音发生器的助听器已被用于增强耳鸣的治疗。本研究的主要目的是通过使用具有集成声音发生器的新型助听器来验证放大和声音发生器的联合使用是否比传统的单纯放大更能有效地减轻耳鸣的困扰。共有 49 名患者接受了盲法随机临床试验。耳鸣困扰通过耳鸣残疾量表和数字量表进行测量,并且还进行了耳鸣的心理声学测量。声音发生器设置为能够提供耳鸣缓解的最低强度。结果表明,在联合适配组和仅放大组中,有 62.5%的患者耳鸣困扰程度降低,78%的患者耳鸣困扰程度降低。组间差异无统计学意义。
