TTS2 of 20dB was produced in a group of subjects using a 1000 Hz pure tone. All TTS and related measurements were made at 1500 Hz. The recovery of TTS, and of TLS or 'temporary loudness shift' (measured against a reference tone at 20db, 40dB and 60dB SL in the opposite ear), as well as N1-P2 amplitude of the Vertex potential, were plotted. There was an orderly recovery of both TLS and TTS although the rate of recovery of the latter was noticeably more rapid. Recovery of N1-P2 amplitude was much less orderly, although it did recover in much the same way. When the amplitudes were measured at 40dB SL the recovery was more orderly and followed the course of TTS more closely. It was concluded that any relation between N1-P2 amplitude and growth of loudness was indirect.
使用1000赫兹纯音在一组受试者中产生了20分贝的暂时性阈移（TTS2）。所有TTS及相关测量均在1500赫兹下进行。绘制了TTS的恢复情况，以及响度阈移（TLS）或“暂时性响度变化”（相对于对侧耳中20分贝、40分贝和60分贝感觉级的参考音进行测量），以及顶点电位的N1 - P2振幅。TLS和TTS均有规律地恢复，尽管后者的恢复速度明显更快。N1 - P2振幅的恢复不太规律，尽管其恢复方式大致相同。当在40分贝感觉级测量振幅时，恢复更有规律，并且更紧密地跟随TTS的过程。得出的结论是，N1 - P2振幅与响度增长之间的任何关系都是间接的。
