It's not nonsense to use acoustic events to detect slow failures in engineering structures. In fact this is somewhat common, for example to detect failing steel inside reinforced concrete structures.[1] It's definitely nonsense to assume that because the boat didn't immediately implode after a big cracking sound was heard that you're all good.

- numpad0 3y agoI mean, if I were jumping on a wooden board and it started reducing in snapping noises, I'd probably feel the board weakening, not hardening and improving. The logic in above quoted sentence seems to be drawing a completely opposite conclusion from intuition.
- AlexandrB 3y agoIt probably depends on all kinds of things - like the materials involved and the nature of the overall structure. I could see there being "settling" events where a structure is stronger overall after a bunch of noises but I suspect that doesn't apply to a carbon fibre cylinder.
