Whale songs are some of the most beautiful, cathartic sounds in nature. These extraordinary creatures use sound to socialize, to mate, to find food, and avoid predators. But for aquatic animals, the sounds of human activity can be absolutely devastating. With underwater noise pollution on the rise, what can we do to ensure the survival of these amazing creatures? Featuring acoustician Al Jones, Professor John Hildebrand of the Scripps Institution of Oceanography, and Vox Senior Producer Christophe Haubursin. Twenty Thousand Hertz is produced by Defacto Sound.
