db is a logarythmic scale (spelling?)
so if you double the decebels, you're actually increasing the noise level by a LOT.
of course, most people who know this dont know another important fact: the human ear drum actually compensates for this!
if the ear drum moved in direct accordance with incrase in noise levels, we'd all break our ear drums every time a truck drove past.
the ear drum moves more as sound increases, but not in direct proportion. it's not quite logarythmic, but it's similar.
