Benefit from a simulated monaural hearing aid was assessed in diotic and dichotic listening conditions in 92 subjects with bilateral, mild to moderate sensorineural hearing impairment. In diotic conditions, subjects scored better on a speech identification task with an 'aid' in their better hearing ear. However, in dichotic conditions, a 'hearing aid' the better hearing ear was of no benefit when the signal came from the side of the poorer ear, while a 'hearing aid' in the poorer ear was of benefit in all listening situations. These results support the hypothesis that patients' preference for using an aid in their poorer hearing ear (Swan et al., 1987) is based on the desire to minimise their disability in the most disadvantageous listening situations.
在92名患有双侧轻度至中度感音神经性听力障碍的受试者中，评估了模拟单耳助听器在双耳同时听和双耳分听条件下的益处。在双耳同时听的条件下，受试者在语音识别任务中，用较好听力耳佩戴“助听器”时得分更高。然而，在双耳分听条件下，当信号来自较差听力耳一侧时，较好听力耳佩戴“助听器”并无益处，而较差听力耳佩戴“助听器”在所有听力情况下均有益处。这些结果支持了以下假设：患者倾向于在较差听力耳佩戴助听器（Swan等人，1987年），是基于在最不利听力情况下尽量减少残疾的愿望。
