To determine the effectiveness of the provision of a hearing aid, some measure of benefit is desirable. Direct determination of benefit is difficult, not least due to the problems inherent in defining what benefit actually is. An alternative approach is to assess aspects of hearing aid use of performance that relate to benefit. Hours of daily use, satisfaction and self-rated performance are measures that might be expected to relate to benefit. The studies reported in this paper examine the relevance and repeatability of these measures. It is concluded that this three-parameter approach provides a simple, relevant and useful way of assessing benefit from amplification which has application in both individual and group studies.
为了确定提供助听器的效果，需要某种衡量益处的方法。直接确定益处很困难，尤其是因为在定义实际益处时存在内在问题。另一种方法是评估与益处相关的助听器使用表现的各个方面。每日使用时长、满意度和自我评估表现是可能与益处相关的衡量指标。本文报道的研究考察了这些指标的相关性和可重复性。结论是，这种三参数方法提供了一种简单、相关且有用的方式来评估放大带来的益处，在个体研究和群体研究中均有应用。
