Delayed emissions are suppressed in proportion to the evoking burst’s audibility

Evidence

There are various ways of influencing the amplitude of the delayed evoked emissions with suppressing sounds. The most impressive effect is the suppression of the delayed evoked emissions by low-frequency sounds, with a period corresponding to the repetition rate of the evoking tone burst. The suppression of the delayed emissions corresponds very closely to the audibility of the evoking tone burst. This result points to the fact that threshold in quiet and the masked threshold are closely related to the different kinds of emissions; these relations are described in the next section. — Professor Dr.-Ing.
