I've seen that result more than a few times, where the acoustic roll off kicks in quite a bit higher than where cabin gain starts. I've also seen guys measure low frequency peaks that shouldn't be there, which usually ends up being ambient noise ranging from heating/cooling equipment to road traffic, but those tend to be narrow bandwidth.
I've measured 20-25Hz content at major concerts that was at the same level whether the band was playing or not. It was audience foot traffic, road traffic, refrigeration equipment and generators. Taking a control measurement when the venue was empty it wasn't there.
