Low-frequency rarefaction impulses completely suppress evoked emissions
Evidence
At a time that corresponds to the moment of the suppressor’s rarefaction maximum, the emission disappears completely. During the period which lies between the maximum of rarefaction and the maximum of condensation, the time function of the emission remains almost unchanged. In the neighbourhood of the condensation impulse, emissions are again reduced but not as much as near the maximum of the rarefaction. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
