Audible sound drops to zero when listener is at a non-zero amplitude sound wave #15

To reproduce:

Open 'Intro' screen
Check 'Audio Enabled' and 'Listener'
Move the listener all the way to the right
The audio will be silent

The sound should have a non-zero amplitude at this point, consistent with the inverse-square law. This is an important pedagogical aspect that should block publication in my opinion. It should be relatively straightforward to track this down and implement the correct audio behavior.

The physics has been updated to apply the inverse square law correctly. Tested the audio on all screens and everything is sounding really good. Closing.
