    I heard about that, but I find it very unlikely that they could make a noise loud enough on the carbon fiber hull, not exactly known for it’s acoustic properties and the resin acts as a sound damper. I’m not a material or acoustic engineer though, so who knows. Plus, the article did say that the sounds had stopped.

      I feel like if there was a way to dampen sounds that well then military submarines would have adopted it long ago. No idea though.

        I don’t mean it’s meant to dampen sound, just that carbon fiber that the hull is made from doesn’t conduct sound waves like metal. But someone else kindly reminded me that I forgot about the titanium cap or the sub

      I believe the forward end cap (where the porthole is installed) is titanium, and exposed on both sides, so presumably that’s what they’d be banging on.
