Human noise pollution is harming ocean creatures
Noise from vessels, sonar, seismic surveys and construction can damage marine animals hearing, change their behaviors and, in some cases, threaten their ability to survive.
Humans are changing the way the ocean sounds, and it is having a profound impact on marine life.
A major new literature review published in Science on Thursday found that noise from vessels, sonar, seismic surveys and
construction can damage marine animals’ hearing, change their behaviors
and, in some cases, threaten their ability to survive.
“When people think of threats facing the ocean, we often think of climate change, plastics and overfishing,” Neil Hammerschlag, a University of Miami marine ecologist who was not involved with the paper, told The Associated Press. “But noise pollution is another essential thing we need to be monitoring.”

Noise pollution affects marine life worldwide
Man-made sounds in and around the oceans stress marine life and have an impact on marine species and ecosystems by changing the underwater acoustic climate. Hans Slabbekoorn from the Institute of Biology Leiden pleads for technical solutions to mitigate problems of noise pollution. Science review paper on 4 February.
Sound is fundamental to the sensory world of marine life. Animals, from jellyfish to whales, perceive and use sound for many aspects of their daily activities. They find food and each other by listening to the surrounding soundscapes, and hunt or seek shelter guided by acoustics. Global industrialisation of the ocean has led to the rise of noise pollution through noisy human activities in and around the water. Hans Slabbekoorn, associate professor at the Institute of Biology Leiden, investigates the effects of man-made sounds: ‘Noise pollution in and around the water has led to a decline in the presence of natu
Undersea habitats to change, fragment as human-made sounds drown out their voices: study
Scientists claim to have recorded fewer animals singing and calling than in the past with anthropogenic sounds fragmenting their habitats.

Not only are humans changing the surface and temperature of the planet, but also its sounds – and those shifts are detectable even in the open ocean, according to research published Thursday. Changes in the ocean soundscape affect wide swaths of marine life, from tiny snapping shrimp to huge right whales, the researchers found. Sounds travel very far underwater. For fish, sound is probably a better way to sense their environment than light, said Francis Juanes, an ecologist at the University of Victoria in Canada and a co-author of the paper in the journal
Scientists say noise pollution is harming sea life, needs to be prioritized
A metastudy to be published in the journal Science shows that humans have drastically altered oceans underwater soundscapes, in some cases deafening or disorienting whales, dolphins and other marine mammals that rely on sound to navigate.
