I have seen many streamers already knowing if the character died or survived an expedition just by the sound of the shelter trapdoor opening, but it is very difficult for me to know what each sound is, I know they are different but it is difficult for me to detect them, can someone explain it to me please?

skurrpless bro when theres one member in the shelter and u send them if the door close sound is very fast and high pitch they dead bro and if the sound of the door is slow they alive bro

dead= fast high pitch like zrzg

alive= slow like zzkrkgrg
