All service dogs should have a set of muttmuffs in their outing gear, along with water, clean up kit and food. No matter how bomb-proof the service dog is, doggy ears are delicate and loud noises are everywhere - the construction you're passing, the DJ at the party, teens popping balloons outside the mall.
The dog should be able to request their ear defenders as needed.
And if you have a dog that tends toward being noise sensitive - like any hearing alert dog or herding breed dog - it should probably be on as a matter of course whenever you go into city environments.
