在4周的噪音暴露[95 dB(A)]中，缺镁豚鼠的听力损失明显高于喂食富镁饮食的豚鼠。听力损失与淋巴周围Mg含量呈负相关（r = -0.86）。除了这种听觉效应外，细胞内Mg降低，心肌胶原蛋白增加，这两者都与听力损失有关，是由缺镁和噪声应激引起的。
Mg-deficient guinea pigs developed significantly increased hearing loss during 4 wk of noise exposure [95 dB(A)] as compared to animals fed a Mg-rich diet. The hearing loss was negatively correlated to the Mg content of the perilymph (r = -0.86). Besides this auditory effect, there was a decrease of intracellular Mg and an increase of collagen in the myocardium, both of which were correlated to the hearing loss and caused by Mg deficiency and noise stress.
