Hearing in a Noisy Ocean
Humans aren’t the only ones who have difficulty hearing in noisy settings.
Whales and dolphins are having problems hearing in the increasingly noisy oceans of the world. Whales and dolphins use sound to communicate and navigate over hundreds of miles. According to the United Nations, those signals are being drowned out by manmade sounds from commercial shipping, seismic surveys, and underwater sonar. As a result, marine mammals are having difficulty hunting, navigating and contacting others in their group.
One scientist called it an underwater cocktail-party effect, where “no one can understand each other anymore.”
