    Actually it does work with regular sand dunes. The sequential baked layers creates a reasoning champer that amplifies sound at certain frequencies.

    Which means Neil is actually upset with how much scientific world building Frank Herbert did, since it confuses people like him who haven’t studied sand dunes for decades.

      This doesn’t mention anything about it working with any kind of large impact, though. It’s all about higher frequency vibrations from layers of sand moving around. It’s an interesting phenomenon, but jot what is being talked about.

        The resonance depends on the size of the cavity. It’s conceivable that with different sand structure you could get different size resonating chambers. Plus even though a piano is tuned for higher frequency vibrations, it’ll still ring when you thump on it. I’d imagine that’d be the same with these chambers.

          I’m just here to appreciate that you’re explaining this to a user named ‘Cave’.

          What’s the opposite of nominative determinism?
