Dolphins ‘shout’ to compensate for human-made background noise

Research adds to concerns about the impact of human noise pollution on marine life

We have all experienced the frustration of trying to hold a conversation in a loud pub or restaurant. Now researchers have shown that dolphins may face a similar scenario, showing that they shout" to each other when faced with background noise.

The findings revealed that a noisy environment makes it harder for dolphins to communicate and cooperate on tasks, adding to concern about the impact of human noise pollution on marine life.
