The benefit obtained from wearing a hearing aid in either ear was assessed in 52 subjects using an audiovisual test. The sound source was located directly in front of the subject. Overall the subjects obtained more benefit with their aid in their better hearing ear, despite having expressed a preference for using the aid in their poorer hearing ear. Seven of the subjects who had asymmetrical hearing were tested further using an auditory test with the sound source either in front of the subject or to either side. The results suggest that the subjects' preference for the poorer hearing ear are based on a desire to minimise their disability in the most disadvantageous listening situations.
通过视听测试评估了52名受试者佩戴单耳助听器的益处。声源位于受试者正前方。总体而言，尽管受试者表示更倾向于在听力较差的耳朵佩戴助听器，但他们在听力较好的耳朵佩戴助听器时获益更多。对7名听力不对称的受试者进一步进行了听觉测试，声源分别位于受试者前方或两侧。结果表明，受试者对听力较差耳朵的偏好是基于在最不利听力情况下尽量减少自身残疾的愿望。
