Human noise threatens marine life

by Daniel Fink, MD, Chair, The Quiet Coalition

Noise is a health hazard and a public health hazard, causing auditory disorders (hearing loss, tinnitus, and hyperacusis) and non-auditory health problems, including hypertension, cardiovascular disease, and death.

This report by Jim Robbins in the New York Times discusses the hazards of noise for marine life. Noise hurts marine mammals, fish, and even plankton.

An evolutionary biology perspective is helpful in understanding why noise is a problem. Loud noise is rare in nature. All creatures on land or in the sea evolved in quiet. That is the natural state, for plants, animals, and humans.

It looks like all living things need quiet to thrive.

Dr. Daniel Fink is a leading noise activist based in the Los Angeles area. He is the founding chair of The Quiet Coalition, an organization of science, health, and legal professionals concerned about the impacts of noise on health, environment, learning, productivity, and quality of life in America. Dr Fink also is the interim chair of Quiet Communities’ Health Advisory Council, and he served on the board of the American Tinnitus Association from 2015-2018.

Is it too late to save the orcas?

Wanyee Li, Toronto Metro, reports that researchers are concerned about the state of the health of the 78 remaining orcas of the Salish Sea orca population.  “The killer whales are declining for a variety of reasons ranging from infection, starvation, and conflict with large ships, both head-on and from the noise pollution they emit.”  Researchers say they know what to do to save these animals, but the problem is finding the political will to do it.

Kim Dun, an oceans specialist with  World Wildlife Fund Canada, said that “noise pollution is among the biggest threats to the whales,” because a “noisy environment that makes it harder for the whales to do what they need to do to survive.”  The combination of threats is enough “to choke the iconic animals until there are not enough whales to keep the population alive.”

In related news, recordings show that baby humpback whales and their mothers “whisper” just in case killer whales are nearby.  Ecologists studying the humpbacks say that this determination highlights the need to regulate ocean noise, because the discovery “suggests that human-produced machinery sounds could be particularly harmful to calves and their mothers.”
