Not just plastic, intense sound pollution also troubles marine life, as the researchers have claimed in the exhaustive study titled as ‘Sound the Alarm: A meta‐analysis on the effect of aquatic noise on fish behavior and physiology’.


In 1953, Jacques Cousteau, a popular explorer disclosed a documentary based on his adventures performed underwater with a title as ‘The Silent World’, after which a great number of scientists inspired to probe the world under the oceans. “For most of history, man has had to fight nature to survive; in this century he is beginning to realize that, in order to survive, he must protect it,” Cousteau said.

Now more discoverers are even concerned about the drastically rising levels of underwater noise pollution supplied by humans through various rowdy activities, which are really confusing, disturbing and even destroying the numerous species living in the aquatic world.

However, there are lots of different natural sounds taking place in the underwater world, due to which a huge soundscape of bubbles, rumbles, clicks and grunts is produced. Such sounds are formed because of the motions of sea water, atmosphere, animals and sea floor.

But nowadays, such sounds soundscapes also become more intense by the human-made noisy machines. It also includes the ping by military SONAR, roar of different motors and offshore development blasting.

A doctoral student, Kieran Cox from the University of Victoria said in a statement that, “In terms of fish behavior and physiology, it has negative responses across the board. Their foraging behavior, their perception of predation, all of these kinds of things is affected. Stress in fish is going up, across species and across experimental conditions.”
