The Spooky Sound Emitter plays noise slightly further out than the visual radius sphere indicates.
Also, it seems like the radius of the sound doesn’t actually go under how 300 appears visually, so setting it to 100 or lower, for example, causes it to play sounds much further than you’d expect it to.
Notes / Media
(I stand still for the last like 5 seconds of the video because my recording software wouldn’t end the recording despite me spamming the end recording hotkey)
