I am trying to find out how 'flat' is considered 'flat' (frequency
response) in a typical small listening room. I am searching for the
range SPL can vary over 20-20KHz to be considered flat in practice.

If your narrowband response varies +/- 12 dB, you'll be doing better
than the vast majority of rooms out there. Third octave response will
always look better than narrowband, of course.
