Progressive necrosis of the organ of Corti caused by a disturbance of the ionic composition of the Cortilymph resulting from the infiltration of endolymph into the organi of Corti after traumatization of its barrier against the scala media, is greatly intensified by posttraumatic stimulation with noise of physiological intensities. This effect is attributed to oscillation of the cochlear partition, with resultant greater blending of the Cortilymph and the endolymph. Stimulation augments necrosis fourfold towards the base of the cochlea and twofold towards the helicotrema. Posttraumatic stimulation is one of the factors which markedly potentiate the regressive effect of acoustic trauma.
在耳蜗中，由于其与中阶之间的屏障受到创伤后，内淋巴渗入柯蒂氏器，导致柯蒂淋巴离子成分紊乱，进而引起柯蒂氏器进行性坏死。而创伤后受到生理强度噪声的刺激会极大地加剧这种坏死。这种效应归因于耳蜗隔板的振荡，导致柯蒂淋巴和内淋巴的混合加剧。刺激使朝向耳蜗底部的坏死增加四倍，朝向蜗孔的坏死增加两倍。创伤后刺激是显著增强声创伤退行性效应的因素之一。
