Delayed evoked emissions respond linearly to impulses below about 18 dB sensation level

Evidence

In such a display of time functions produced by different sensation levels, it becomes clear that the relative amplitude remains equal at low levels. This means that the delayed evoked emission behaves linearly for sensation levels of evoking impulses smaller than about 18 dB. For larger sensation levels, the relative amplitude decreases, which means - as seen in Fig. 3.17 - that the absolute amplitude remains approximately constant. — Professor Dr.-Ing.
