Healthy guinea pigs were exposed to broadband noise at 115 dBA for 7 days. When perfusion of the scala vestibuli was carried with artificial perilymph containing 43K, the 43K concentrations in the perilymph of the scala tympani were very low in both control and noise-exposed guinea pigs. The transport rate constant for K+ was computed by utilizing compartmental analysis. The results indicate that exposure to noise at 115 dBA for 7 days does not alter the permeability to K+ of Reissner's membrane or the lateral wall of the cochlear duct but does decrease K+ conductance of the organ of Corti.
将健康豚鼠暴露于115分贝的宽带噪声中7天。当用含43K的人工外淋巴进行前庭阶灌注时，在对照和噪声暴露的豚鼠中，鼓阶外淋巴中的43K浓度都非常低。通过利用房室分析计算K+的转运速率常数。结果表明，暴露于115分贝的噪声中7天不会改变Reissner膜或耳蜗管外侧壁对K+的通透性，但会降低柯蒂氏器的K+电导。
