Hearing impairment has been associated with decline in psychosocial function. Previous investigations have reported that the utilization of hearing aids can ameliorate these reductions in psychosocial function. To date, few investigations have examined the effects of frequency modulation technology on hearing handicap, adjustment to hearing loss, and communicative strategies. The purpose of this investigation was to examine these effects and to compare them to the benefits obtained when using hearing aids alone. Subjects ranged in age from 34 to 81 years and had mean pure-tone thresholds consistent with a bilateral moderate to severe sloping sensorineural hearing loss. All subjects wore hearing aids only and hearing aids plus FM system in a randomized fashion. The Communication Profile for the Hearing Impaired (CPHI) was administered prior to fitting the study devices and once a month for three months in each of the two conditions. A statistically significant difference between device conditions was obtained for the Importance of Communication in Work Situations subscale. Additionally, statistically significant differences over time were noted in several CPHI subscales. Despite statistical significance, none of these results were clinically significant. The implications of these results will be discussed.
听力障碍与心理社会功能下降有关。先前的调查报道，使用助听器可以改善心理社会功能的这些降低情况。迄今为止，很少有调查研究过调频技术对听力障碍、听力损失适应情况以及沟通策略的影响。本研究的目的是检验这些影响，并将其与仅使用助听器所获得的益处进行比较。受试者年龄在34岁至81岁之间，平均纯音听阈符合双侧中度至重度斜坡型感音神经性听力损失。所有受试者以随机方式仅佩戴助听器以及佩戴助听器加调频系统。在佩戴研究设备之前以及在两种情况下的每一种情况下，连续三个月每月一次使用《听力障碍者沟通概况》（CPHI）进行评估。在“工作场合沟通的重要性”分量表中，不同设备情况之间存在统计学上的显著差异。此外，在几个CPHI分量表中，随着时间的推移也发现了统计学上的显著差异。尽管具有统计学显著性，但这些结果均无临床显著性。将讨论这些结果的意义。
