I can easily perceive a 5 db increase...I used to live near train tracks and I could tell when those bastards switched to the 110 db max horns from other horns that were "only" 96-100 or 100-105 db (I used a decibel meter to verify it for myself)...and yes I know that going from 105 to 110 db is even more significant than 87 to 92 db...
