摘要为探讨连续或间歇性强噪声暴露引起的听力损失。建立了螺旋耳蜗液-固耦合的三维有限元模型。对模型的可靠性进行了验证，并对耳蜗枢性结构基底膜的应力和幅值进行了分析。结果表明，在同一高压声作用下，耳蜗区高频区的优先疲劳区主要引起耳蜗区的疲劳。较安全的区域是低于70分贝的声压级，而高于90分贝的声压级会加速对耳朵的损害。
Abstract In order to explore the hearing loss resulting from exposure to continuous or intermittent loud noise. A three-dimensional liquid-solid coupling finite element model of spiral cochlea was established. The reliability of the model was verified, and the stress and amplitude of the basilar membrane of the pivotal structure in cochlea were analyzed. The results show that under the action of the same high-pressure sound, the preferential fatigue area of the cochlear high-frequency area mainly causes fatigue in the cochlear. The safer area is a sound pressure level below 70 dB, while one above 90 dB accelerates damage to the ear.
