Abstract
When competing speech sounds are spatially separated, listeners can make use of the ear with the better target-to-masker ratio. Recent studies showed that listeners with normal hearing are able to efficiently make use of this "better-ear," even when it alternates between left and right ears at different times in different frequency bands, which may contribute to the ability to listen in spatialized speech mixtures. In the present study, better-ear glimpsing in listeners with bilateral sensorineural hearing impairment, who perform poorly in spatialized speech mixtures, was investigated. The results suggest that this deficit is not related to better-ear glimpsing.
摘要
当相互竞争的语音在空间上分离时，听众可以利用目标与掩蔽声比例更佳的耳朵。最近的研究表明，听力正常的听众能够有效地利用这只“更佳耳朵”，即使它在不同频段的不同时间在左耳和右耳之间交替，这可能有助于在空间化语音混合中聆听的能力。在本研究中，对双侧感音神经性听力损失且在空间化语音混合中表现不佳的听众的更佳耳朵捕捉情况进行了研究。结果表明，这种缺陷与更佳耳朵捕捉无关。
