 | | It is difficult for us, because we live on land and rely more on our eyes than our ears, to comprehend the profound importance of sound to whales and dolphins. |
 | | These intelligent animals use sound to communicate with one another, to maintain their social group, to understand their environment, to navigate, to hunt and stun prey. |
 | | The effects of loud, man-made noise under water can range from masking the noises made by the animals themselves so they are no longer able to communicate with one another, through to frightening or chasing animals away from important habitat and, in the worst cases, loud noise can even kill. |
