To determine whether listeners with primarily high-frequency sensorineural hearing loss (HF SNHL) perceived benefit from amplification provided by completely-in-the-canal (CIC) hearing aids.
The Hearing Handicap for the Elderly-Screening version, the Abbreviated Profile of Hearing Aid Benefit, and the Satisfaction With Amplification in Daily Life questionnaires were mailed to 2 groups of listeners (n = 79) who matched preset criteria, including threshold at 2000 Hz and use of CIC amplification. Sixty-seven percent (n = 53) of the questionnaires were returned and were divided into 2 groups. Group I (n = 26) consisted of listeners with normal hearing through 2000 Hz, and Group II (n = 27) consisted of listeners with normal hearing only through 1000 Hz.
Results revealed that both groups perceived significant hearing handicap, hearing aid benefit, and hearing aid satisfaction. Differences between the 2 groups on the 3 measures, however, were not statistically significant.
Listeners with HF SNHL perceived benefit and satisfaction from amplification with CIC hearing aids. Individuals with SNHL limited to the high frequencies should be considered candidates for amplification.
确定主要患有高频感音神经性听力损失（HF SNHL）的听力受损者是否能从耳道式（CIC）助听器提供的放大功能中获益。
将《老年人听力障碍筛查版》《助听器效益简要概况》和《日常生活中对放大功能的满意度》问卷邮寄给两组符合预设标准的听力受损者（n = 79），这些标准包括2000赫兹处的听阈以及使用CIC放大功能。67%（n = 53）的问卷被收回，并分为两组。第一组（n = 26）由2000赫兹听力正常的听力受损者组成，第二组（n = 27）由仅1000赫兹听力正常的听力受损者组成。
结果显示两组都感受到了显著的听力障碍、助听器效益和助听器满意度。然而，两组在这三项指标上的差异无统计学意义。
患有HF SNHL的听力受损者从CIC助听器的放大功能中获得了益处和满意度。高频受限的感音神经性听力损失患者应被视为放大功能的适用对象。
