Gena, i don't think we are discussing the same concept, or rather in different terms.

Yes, i can hear a jet plane 10,000 feet in the air from the ground.
Does that sound "fill" the entire air space around you?
No. Sound energy is dispersed in multiple directions and lost over the distance AND volume of the medium in which it is presented.
Volume is missing from this equation as is any in room variables that apply to reverberation per my earlier post.
Quit thinking linear.
