This is weird

Put on headphones, make sure everything in the room is quiet, and listen to this. It's short, don't worry. It's a 3-D sound thing, and although it's really cheesy (fake Italian accents), it's really powerful. The narrator explains some things about why your brain processes the sound in the way that it does, but maybe Elizabeth can expand upon it? I feel like it's related to everything we've been discussing in class, especially in The Echo Maker.
