Well, intuitively, things do get louder as they near the ground, as they transit from being monopoles to 'hemipoles' (made that word up, but you know what I mean) and I wonder if this is frequency-dependent, so that they become 'bassier' as they near the ground (same principle as putting the subs on the floor to get a 3db lift).

It certainly worked but so did end making things slightly quieter as they got higher and increasingly higher in pitch. I cant help thinking of the way looney tunes cartoons intuitively picked up on this when making their sound effects(when roadrunner falls of a cliff a sound goes down - when he is blown into the sky a noise goes higher in pitch) . Intuitive I guess but its nice to see some of the science behind it .
