Blast injury typically consists of a mixed conductive and sensorineural hearing loss. The sensorineural component includes temporary as well as permanent threshold elevations. Auditory brainstem evoked potentials (ABEP) are sensitive to functional changes in various levels along the auditory pathway. ABEP were recorded from 37 survivors of blasts and latency measures were correlated with clinical findings. Prolongation of peak latencies was correlated with the conductive component of blast-induced hearing loss, as well as with the TTS component of the sensorineural impairment. No central effects of blast on the auditory system were detected. In addition to their objectivity, ABEP hold the promise of differentiating between the permanent and temporary effects of blast on hearing.
爆炸伤通常包括混合性传导性和感音神经性听力损失。感音神经性成分包括暂时性和永久性阈值升高。听觉脑干诱发电位（ABEP）对听觉通路各水平的功能变化敏感。对37名爆炸幸存者进行了ABEP记录，并将潜伏期测量结果与临床发现进行了关联。峰潜伏期延长与爆炸所致听力损失的传导性成分以及感音神经性损伤的TTS成分相关。未检测到爆炸对听觉系统的中枢效应。除了其客观性外，ABEP有望区分爆炸对听力的永久性和暂时性影响。
