Using screening questionnaires we were able to detect individuals aged 50-65 years with hearing disability in a general practice population. Those who had better ear hearing levels of 30 dB or worse were invited to take place in a cross-over study comparing the acceptability of a monaural or binaural hearing-aid fitting. Fifty-five per cent ultimately opted for a binaural fitting and had greater hearing disability and worse mean hearing levels than those who opted for a monaural fitting. They made their choice for acoustical reasons, particularly on the basis of improved localization ability.
通过使用筛查问卷，我们能够在普通执业人群中检测出年龄在50至65岁之间的听力残疾个体。那些较好耳听力水平为30分贝或更差的人被邀请参加一项交叉研究，比较单耳或双耳助听器验配的可接受性。最终，55%的人选择了双耳验配，他们的听力残疾程度比选择单耳验配的人更严重，平均听力水平也更差。他们出于声学原因做出选择，特别是基于改善的定位能力。
