If i make it they in the same time it will sounds too much loud

I recorded this sound from Dead Space 2 and yes, Isaac have his own heart sound. So then in mod it sounds with suit *beep* like you asking :)

i say this because i think that the beeping is not consistent with the sound of the heart beating. it should be beeping whenever the heart is pounding at the same time lol

is the beeping sound overlapping the heartbeat sound? or is this the original sound file from the game?
