^haha.... that's not exactly how it works for the aviary. Most aviaries are basically fencing/netting so the birds & whatnot are outside, but not "loose". Now I'm not exactly sure about the extent of aviary theming the Pteranodon coaster would've had (or the new one being built in Japan), but it wont be an "indoor" coaster because that structure would have to be huge & wouldn't be practical at all.... but my point is, the noise would be blocked because it wouldn't be enclosed like Mummy.
FunFact: the original design for JPRA featured an Aviary scene, but unfortunately it was cut from the final ride (obviously).
