Whales 'cannot out-sing' human noise pollution

February 26, 2024

Baleen whales have evolved a special voice box to help them to sing underwater -- but this could also make them uniquely vulnerable to being drowned out by human noise pollution, according to new research published Wednesday. While toothed whales have a nasal vocal organ, filter-feeding baleen whales use a larynx, although scientists had not figured out exactly how it created the vocalisations. But the scientists also found a potentially serious challenge for the whales: the struggle to make themselves heard over noise pollution from ships. This is particularly important at mating sites where, depending on the season, noise pollution can disrupt reproduction. Researchers say there is an urgent need to regulate underwater noise.
