The data of 46 adults with single-sided sensorineural deafness who were candidates for bone-anchored hearing aids (Baha) CROS (contralateral routing of signals) were analyzed. All candidates tested a Baha with a headband in their normal environment. Subsequently, 29 of the candidates chose a permanent Baha CROS fitting, and 17 declined, thus forming the two study groups. No significant difference regarding age, sex or duration of deafness was found between the two groups. Similarly, the transcranial attenuation was not significantly different between those who accepted and declined a Baha. Subjects with some residual hearing in their poorer ear tended to decline a Baha, but the effect was not statistically significant. For a subset of 28 subjects, the Bern Benefit in Single-Sided Deafness questionnaire was administered. The questionnaire consists of 10 visual analogue scales rating the subjectively perceived benefit of the Baha or any other CROS device in different situations. Scores were found to be significantly higher for speech understanding at some distance (p = 0.026), for speech understanding in noise (p = 0.037), for group conversations (p < 0.01), and for the overall benefit (p < 0.01) for those candidates who chose to use a Baha as a CROS device permanently.
对46名单侧感音神经性耳聋且适合骨锚式助听器（巴哈）对侧信号路由（CROS）的成年人的数据进行了分析。所有受试者在其正常环境中佩戴了头带式巴哈进行测试。随后，29名受试者选择了永久性巴哈CROS装置，17名受试者拒绝，从而形成了两个研究组。两组在年龄、性别或耳聋持续时间方面未发现显著差异。同样，接受和拒绝巴哈的受试者之间的经颅衰减也无显著差异。较差耳有一些残余听力的受试者倾向于拒绝巴哈，但效果无统计学意义。对28名受试者的一个子集进行了单侧耳聋的伯尔尼益处问卷调查。该问卷由10个视觉模拟量表组成，用于评定受试者在不同情况下对巴哈或任何其他CROS装置主观感知到的益处。结果发现，对于那些选择永久使用巴哈作为CROS装置的受试者，在一定距离处的言语理解（p = 0.026）、噪声中的言语理解（p = 0.037）、小组对话（p < 0.01）以及总体益处（p < 0.01）方面的得分显著更高。
