Added Ability for Looping Sounds to be heard from further away. (#4857)

# Allows Looping Sounds to be heard from further away. 

# Explain why it's good for the game
allows for looping alarms to be proximity based and heard from more than
1 room away should one desire.



side note... I was eating pizza and there was hella black ash on the
bottom. I think they burned garlic bread. It was nasty.


# Testing Photographs and Procedure
screenshot a sound? 

okay uhh... I uhh... adjusted settings and played a looping sound and
walked away from it.
