Whales rely heavily on their sense of hearing. The deep, dark waters they live in make it difficult for them to rely on other senses, so they evolved to become extremely sensitive to the sounds that surround them.

They are social animals who communicate through incredibly elaborated systems of sound. They recognise each other thanks to sounds, they use those sounds to tell each other things, noises warn them when a danger is coming and they even find food thanks to that stunning sense of hearing they have. 

Noise pollution makes all of this impossible for them. It makes it impossible to recognise or understand their world. It’s physically painful to them and it overshadows their voices.

Exactly why whales and dolphins strand is not fully known but factors can include sickness, navigational error, geographical features, a rapidly falling tide, being chased by a predator, or extreme weather.

Those are all hypotheses and sadly hypotheses are all we have when it comes to understanding this phenomenon. But I would like to mention yet another hypothesis, or better, one reason why “navigational error” might occur.

Noise pollution.
