Custom sound is always loud regardless of distance

I have a custom sound set up like this:

For whatever reason, it always comes out playing at full volume regardless of how far I am from the source.

 

This is the sound file: https://dl.dropboxusercontent.com/u/109892108/SomeDayMyPrinceWillCome01.wav

 

What am I doing wrong?
