Reports of hearing disabilities, particularly those acoustically and perceptually dynamic circumstances, are associated with compromised binaural capacities. Those disabilities that are compromised largely correspond to the areas where benefits of bilateral fitting over unilateral fitting emerge. The singular exception is for disabilities in "Sound quality and naturalness". When binaural capacities are measured by traditional static masking level difference paradigms, relationships between compromised binaural capacity and self-reports of disability are largely absent. However, when masking level differences are assessed using dynamic parameters that are more representative of the conditions experienced in everyday living then significant associations between binaural capacities and self-reports of disability do emerge. We contend that, for both the self-report domain and the psychoacoustical domain, procedures should be more properly representative of the dynamic environments that listeners are routinely exposed to.
听力残疾的报告，尤其是那些在声学和感知动态环境下的报告，与双耳功能受损有关。那些受损的残疾情况在很大程度上与双侧佩戴优于单侧佩戴的受益领域相对应。唯一的例外是“声音质量和自然度”方面的残疾。当通过传统的静态掩蔽级差范式来测量双耳功能时，双耳功能受损与残疾自我报告之间基本不存在关联。然而，当使用更能代表日常生活中所经历情况的动态参数来评估掩蔽级差时，双耳功能与残疾自我报告之间就会出现显著关联。我们认为，对于自我报告领域和心理声学领域而言，相关程序都应该更恰当地代表听众日常所接触的动态环境。
