在海洋里生活的鲸类动物拥有极为精密复杂的发声系统和声音处理系统,它们能利用声音来实现个体间通讯、导航、定位、寻找食物以及逃避天敌的目的。严重的噪声污染,会损伤鲸类的听觉系统,甚至导致生命体死亡。科学家发现,大型船只的低频声会覆盖鲸类的通讯发声,进而影响它们的活动如迁移行为。低频噪声会使得北大西洋露脊鲸的糖皮质激素降低,导致生命体的代谢紊乱。军舰使用的中频声呐会引起鲸类听觉器官受损,引发大规模搁浅。海上爆破产生的噪声会导致附近海域的中华白海豚脑部充血等等。 Cetaceans living in the oceans have extremely sophisticated vocal systems and sound processing systems that use sound to communicate, navigate, locate, find food and evade predators. Severe noise pollution can damage whale-like hearing systems and even lead to the death of living beings. Scientists have found that the low-frequency sounds of large vessels cover the whales’ communication sounds, which in turn affect their activities such as migration. Low-frequency noise can reduce the glucocorticoids in the Northern Atlantic right whales, leading to metabolic disorders in the living body. The intermediate-frequency sonar used by the warships can cause damage to the cetacean cords, causing large-scale stranded. Noise generated by blasting at sea can lead to congestion of the brain of the Chinese white dolphin in nearby waters.
