Aversiveness of loud sounds is a frequent complaint by hearing aid users, especially when fitted bilaterally. This study investigates whether loudness summation can be held responsible for this finding. Two aspects of loudness summation should be taken into account: spectral loudness summation for broadband signals and binaural loudness summation for signals that are presented binaurally. In this study, the effect of different symmetrical hearing losses was studied. Measurements were obtained with the widely used technique of Adaptive Categorical Loudness Scaling. For large bandwidths, spectral loudness summation for hearing-impaired listeners was found to be greater than that for normal-hearing listeners, both for monaurally and binaurally presented signals. For binaural loudness summation, the effect of hearing loss was not significant. In all cases, individual differences were substantial.
对响亮声音的不适是助听器用户经常抱怨的问题，尤其是当双侧佩戴时。本研究旨在探讨响度总和是否对此发现负责。响度总和有两个方面需要考虑：宽带信号的频谱响度总和以及双侧呈现信号的双耳响度总和。在这项研究中，研究了不同对称听力损失的影响。测量结果是使用广泛使用的自适应分类响度标度技术获得的。对于大带宽，发现听力受损者的频谱响度总和大于正常听力者，无论是单侧还是双侧呈现的信号。对于双耳响度总和，听力损失的影响不显著。在所有情况下，个体差异都很大。
