Sound Pollution in the Ocean

In areas with heavy ship traffic, the sound that blue whales create is at the same frequency as noise created by the ship. So it's like being in a cocktail party, for example. Everyone's talking at the same time, and you know someone said your name, but you don't know where that sound is coming from. You know, it's just a murmur of sound. And so for whales, if everything's at the samefrequency, if I'm talking to you and someone's also talking across us at the same volume, then I can't hear you. But it must be pretty exhausting for these animals to have noise, constantly bombarding them day in and day out.
