Abstract
The effects of cross-hearing from the non-test ear were examined during the acquisition of the auditory brain-stem evoked response (ABR). Effective masking levels were derived from a normal hearing subject and the results used to obtain masked versus unmasked ABR thresholds in varying types of unilateral hearing loss. The results indicate that in the presence of a hearing loss adequate masking of the non-test ear is essential for valid ABR results.
摘要
在听觉脑干诱发电位（ABR）采集过程中，研究了非测试耳交叉听力的影响。从一名听力正常的受试者得出有效掩蔽水平，并将结果用于获取不同类型单侧听力损失情况下的掩蔽与未掩蔽ABR阈值。结果表明，存在听力损失时，对非测试耳进行充分掩蔽对于获得有效的ABR结果至关重要。
