- Ok, what about if you fired a .45 ACP on Mars, or somewhere else
- with an extra thin (~1-2% of sea level pressure), would the noise
- the shooter hear be ~1-2% as intense as it would be at sea level,
- ie linearly proportionate to the pressure, or is it some other
- much more complicated calculation?

- (I don't know why I responded to this, but the image of figures
- in pressure suits running tests on 1911s was too much for me. %^)
