You explain to the whales nothing could be easier than repurposing some military submarine detection sound arrays already spread through all the world’s oceans. The whales are at first worried about the ethics, but you explain the US military is an unethical institution, so it’s not possible to commit a wrong by taking from it. Moral quandaries resolved, you and the whales quickly and easily reroute the entirety of the US navy's hydrophone system to play through your camp's speakers. Soon, you are surrounded by the sound of the world's whales, the ethereal quality of it seems to move around with you in space, mirroring their movement through the oceans. The audio installation is quite amazing, and a wonderful time is had by everyone.
