Added code to prevent loud sounds from being overtaken by quiet sounds. 

This prevents the weird effect where you hear a bunch of sounds of
majorly different volumes starting and stopping. If, for example, you
have several mines exploding nearby as well as several mines exploding
far away at the same time, you will hear the near ones and not the far
ones.
