In order to reduce measurement time we have used part of the interstimulus interval of the slow cortical responses to record fast brain stem responses. For this purpose we reconstructed a programmable audiometer and preamplifier which are controlled by a computer. These, with 1/4 ms-click and tone-burst stimulation simultaneously gained fast and slow responses, not only give a frequency-related view of the threshold and the kind of hearing loss--because of amplitude and latency--, but also in some cases--because of differences between both responses--give ideas of the possible location of the hearing impairment through the auditory pathways. The audiological value of this new method is discussed and explained by giving examples of two interesting cases, one central-neural hearing loss and one questionable aggravation.
为了缩短测量时间，我们利用慢皮层反应的部分刺激间隔来记录快速脑干反应。为此，我们重建了一台由计算机控制的可编程听力计和前置放大器。这些设备通过1/4毫秒的滴答声和短纯音刺激同时获得快速和慢速反应，不仅能从频率相关的角度，通过振幅和潜伏期了解阈值及听力损失类型，而且在某些情况下，由于两种反应之间的差异，还能通过听觉通路对听力损伤的可能位置有所了解。通过给出两个有趣病例的例子，一个是中枢神经性听力损失，另一个是可疑的听力恶化，来讨论和解释这种新方法的听力学价值。
