[openal] Attenuation Roll-Off problems (too silent)

I'm still trying to figure out why the attenuation in OpenAL is not 
working properly.

According to the documentation a roll-off of 1 is the default or 
"natural". If I use this though and I have let's say a sound source a 
couple of meters above ground (think of an airplane or similar) with 
gain set to 1 then it is pretty much inaudible a couple of meters below 
on the ground. I tried setting the gain like to 10 but this does not 
help much. I ended up using a roll-off of 0.05 to make the sound audible 
on the ground.

This sounds wrong to me. Is the documented roll-off default value wrong? 
Is something else wrong? Can't be a sound is only audible a few meters 
away even if it is like a large engine running which you can hear over a 
great distance.

Yours sincerely
