Actually, it depeneds on the frequency. Humans are least sensitive to the bass frequencies and high frequencies, so we're more apt to notice changes in the midrange. (2500-5000hz is the range we are most sensitive to, due to the resonance of our ear canal). See this page for more info: http://hyperphysics.phy-astr.gsu.edu/hbase/sound/eqloud.html

So what makes sense is that in the upper midrange, 2-3db might sound twice as loud, but for us to make the same distinction for the very high or very low frequencies, it may require a 6db difference or more.
