But the ones that have been unable to get used to it wouldn't be there anymore, 
would they?

The types of noise may have different effects on different species too.  The 
steady roar of a jet is very different to the sharp clatter of a helicopter, 
for example.  Some noise regulations even take the extra annoyance of 
"impulsive" noises into account by deeming them to be several decibels higher 
than the measured levels.
