"Room Correction" what the H..?

My Behringer 2496 equalizer has an automatic equalization capability, using a calibrated mic. One option when performing the Auto Eq process is somthing called "Room Correction". To quote the owner's manual this "cuts the high frequencies and boosts the low frequency range by "tilting" the desired response curve by 1 dB/oct". There is no further explanation.

This is a very gradual tilt that extends uniformly over the full 20 - 20KHz range. I rather like the result, but wonder about the basis for this equalization. Is it some commonly used aspect of pro sound reenforcement that I as a lowly audiophile have never heard about?

That does seem like a strange "room correction". It assumes that rooms are bright and have linearly poor bass response, which is a very strange assumption. Bass issues usually peak or drop off at irregular intervals dependent on the room characteristics (e.g., dimensions). The calibrated mic is a good idea since it should pick up the uneven responses, but the 1db/octave linear boost of bass does not seem to be a room correction factor; it seems to be an equipment correction or personal preference adjustment.
