双耳助听器的好处是有据可查的，但许多助听器用户仍然只戴一个助听器。这是合理的，闭塞效应是部分原因，一些助听器用户不戴两个助听器。在这项研究中，我们量化了主观的闭塞效应，要求10个有经验的用户的双边助听器和参考组的10个正常听力的人来评价自己的声音的自然度，而阅读的文本样本大声。在单侧与双侧条件下，对耳模和定制助听器中的各种通风口设计的主观闭塞效应进行了评价。除非阻塞式耳塞选项外，所有通气孔设计的双侧助听器的主观阻塞效应显著更高。在单侧和双侧条件下，采用更开放的排气口设计可降低主观闭塞效应。假设闭塞效应是双侧助听器使用的障碍，这些结果表明开放式助听器配件有助于促进使用两种助听器。
The benefit of bilateral hearing aids is well documented, but many hearing-aid users still wear only one aid. It is plausible that the occlusion effect is part of the reason for some hearing-aid users not wearing both hearing aids. In this study we quantified the subjective occlusion effect by asking ten experienced users of bilateral hearing aids and a reference group of ten normal-hearing individuals to rate the naturalness of their own voice while reading a text sample aloud. The subjective occlusion effect was evaluated in the unilateral versus bilateral condition for a variety of vent designs in earmolds and in a custom hearing aid. The subjective occlusion effect was significantly higher for bilateral hearing aids with all vent designs with the exception of a non-occluding eartip option. The subjective occlusion effect was reduced with the more open vent designs in both the unilateral and bilateral conditions. Assuming that the occlusion effect is a barrier to bilateral hearing aid use, these results indicate that open-hearing-aid fittings can help promote the use of two aids.
