Going from 120-110 down to 100-90 isnt really a significant decline, it went from unbearably torturous to really annoying. Airports nowadays still create significant noise pollution in their surroundings.
- amelius 3y agoYes, from the graph it seems we've almost reached the asymptote and noise isn't going down much from here.
- marcinzm 3y ago>it went from unbearably torturous to really annoying That's like saying the difference between getting stabbed and pushed isn't big since both are physical assaults. It is. 120 is at the level of ear injury and pain even in the short duration of a takeoff. 90 isn't.

- class3shock 3y agoI'm not going to say 100db isn't loud but db is a logarithmic scale, so even 110 down to 100 isn't a 9% reduction but an order of magnitude drop. Literally the difference between a jackhammer and a nail gun. Sound drops 4x for each 2x increase in distance from the source. So another way to put it is, if you cut sound by 10x, you are cutting the distance of severely noise polluted area around by more than 4x.
