Dolphins have to ‘shout’ to hear each other over noise pollution, research reveals

Dolphins have to ‘shout’ to hear each other over ocean noise pollution, a new study reveals. Dolphins in noisy environments struggle to communicate and cooperate on tasks, researchers from the University of Bristol, UK, have found. This could have wide ranging implications for marine life. Sound travels far further underwater than light, and up to three times faster in water than in air, making it an essential form of communication for dolphins and other marine mammals. They rely on vocalisation to find prey and mates, to navigate, and to work together. In recent decades, human-made underwater…
