BMC Geriatr:发展中国家老年人可编程穿戴数字助听器的有效性研究

2021-08-09 AlexYang MedSci原创

助听器是听力康复的重要辅助设备。然而,

助听器是听力康复的重要辅助设备。然而,在一些发展中国家,常见的商业助听器的成本往往高于个人的平均月收入。因此,非常有必要在当地生产更便宜但仍然有效的助听器。泰国生产的P02助听器就是为了满足这一要求而设计的。

近期,有研究人员比较了P02助听器与两种常见的市售数字助听器(Clip-III™和Concerto Basic®)的效果

2012年10月至2014年9月,研究人员在泰国一个农村社区进行了一项交叉设计的前瞻性、随机对照试验。有73名中度至重度听力损失患者(平均年龄为73.7±7.3岁)纳入该研究,通过这些患者,研究人员评估了助听器的性能,包括探针麦克风的实耳测量、功能增益、语言辨别力,以及参与者对整体声音质量的感知和设备设计的满意度。

在评估的三种助听器中,功能增益和语言辨别力没有统计学上的显著差异(P值>0.05)。三种助听器的真耳测量结果在93%的参与者中符合目标曲线。遵循目标曲线的P02助听器的最佳真耳测量值在高频率下明显低于Clip-III™和Concerto Basic®(P值<0.05)。然而,参与者对P02助听器的总体音质评价高于Clip-II,但低于Concerto Basic®(p值>0.05)。参与者对P02助听器在设计和用户友好性方面提供了最高的满意度评价,且具有统计学意义(P值<0.05)。

三种助听器的功能增益和语言辨别力比较

综上所述,P02助听器对于有听力障碍的泰国老年人是一种有效的设备。此外,其现代化的设计、简单的使用和易于维护的特点使得该产品对这一群体具有吸引力。这些优点支持了这种助听器的康复潜力及其对发展中国家的老年人生活质量的积极影响。
