It is well documented that the majority of individuals with normal hearing have a right ear advantage for dichotic speech material. There is evidence, however, that individuals with flat sensorineural hearing loss demonstrate a left ear advantage after they have used amplification on the left side. The present study examined whether these findings could be extended to a population with high-frequency hearing impairment. The subjects were administered dichotic consonant-vowel syllable tests prior to a monaural hearing aid fitting, and the tests were repeated after 1 month and again after 6 months of hearing aid use. The results revealed a group right ear advantage prior to the hearing aid fitting, although there was considerable individual variability. No consistent changes in the test scores were shown to be associated with monaural hearing aid use in either the right ear or the left ear.
有充分的文献记载，大多数听力正常的人在双耳分听言语材料时表现出右耳优势。然而，有证据表明，患有平坦型感音神经性听力损失的个体在左耳使用放大设备后表现出左耳优势。本研究探讨了这些发现是否可以推广到高频听力受损人群。在单耳佩戴助听器之前，对受试者进行了双耳辅音-元音音节测试，并在佩戴助听器1个月后和6个月后再次进行测试。结果显示，在佩戴助听器之前，该组存在右耳优势，尽管个体差异较大。在右耳或左耳使用单耳助听器后，测试分数没有显示出一致的变化。
