If we're trying to leverage how sound works in real life. The suggestion was blow out canopy, enter Coriolis where there's actually an atmosphere, eject UA, listen. Risky though, when I tried ejecting a standard canister inside a Coriolis to see if it was possible it bounced off the walls a few times (but was fine).
I would love to see an entire station filled with commanders with blown canopies... LISTENING!!!!
