This is sleep-learning, where you get a tape recorder, you put it beside your bed and it turns on in the middle of the night when you're sleeping, and you're supposed to be learning from this.
It's very powerful. And I have to admit, it feels a bit spooky to walk down to the ice in the nights, changing batteries in my sound recorder while being surrounded by these loud, strange sounds.
