The clinical use of the action potentials (SAP) of the acoustic nerve stimulated by sinustone bursts of relatively fast rise times has been described extensively elsewhere. The use of sinus tone bursts with relatively long rise times has the advantage of high frequency specifity. Thresholds for frequences of 500 Hz upwards may be found within a +/-12.5 dB SL confidence intervall. Judging the relation between the N1 amplitude in muV and the stimulus level in dBHL - the socalled Input/Output (I/O) curve - a differentiation between recruiting and non recruiting receptor behaviour can be made. The amplitude latency behaviour of the SAP gives additional information on the acoustic nerve's fibres in the high frequency range. The described method seems expecially useful to determine the Corti' organ's state in problematic cases of hearing defects in children.
由上升时间相对较快的短纯音猝发刺激听神经产生的动作电位（SAP）的临床应用在其他地方已有广泛描述。使用上升时间相对较长的短纯音猝发具有高频特异性的优势。对于500Hz及以上频率，可在±12.5dB SL置信区间内找到阈值。通过判断以微伏为单位的N1波幅与以dBHL为单位的刺激强度之间的关系，即所谓的输入/输出（I/O）曲线，可以区分募集型和非募集型感受器行为。SAP的波幅潜伏期行为在高频范围内为听神经纤维提供了额外信息。所描述的方法在确定儿童听力缺陷疑难病例中柯蒂氏器的状态时似乎特别有用。
