The objective of this study was to assess the ease of handling, comfort, and general effectiveness of three types of earmould in patients who, due to their age, could be expected to experience handling difficulties. The three mould types were, meatal tip, skeleton and skeleton with the 'top prong' removed. The results indicated that the skeleton with the top prong removed was the best in all contexts but one. It was easiest and quickest to fit and least likely to be badly fitted. Only in feedback control did it perform less well. It was concluded that it should be routinely used for elderly patients fitted with low gain hearing aids.
本研究的目的是评估三种耳模对因年龄原因可能会在佩戴时遇到困难的患者的操作便利性、舒适度和总体效果。这三种耳模类型分别是耳道式、骨架式以及去除“顶叉”的骨架式。结果表明，去除顶叉的骨架式耳模在所有情况下（有一种情况除外）都是最佳的。它佩戴起来最简便快捷，且佩戴不当的可能性最小。只有在反馈控制方面它的表现稍逊一筹。研究得出结论，对于佩戴低增益助听器的老年患者，应常规使用这种耳模。
