According to Columbia University of New York, it's actually the other way around...

The difference to our ears between 101 Hz and 100 Hz is much greater than the difference between 1,001 Hz and 1,000 Hz. We don’t hear a change of 1 Hz for each; instead we hear a change of 1,001/1,000 (= 1.001) as compared to a much bigger change of 101/100 (= 1.01).

Change in lower frequencies are much more noticeable than changes higher up (surprised me, but makes sense when you think about it).
