Doubt it.
The person using a leaf blower isn't using one because they enjoy it. They have another 5000 places to manicure afterward—a rake no longer enters the equation since its coefficient of expedience is so low. This in turn, of course, impacts price. The employer of said manicurist passed the buck because they didn't have the time to rake it themselves.
I'd imagine that for those irritated by things of the sort, when it comes to irritants, unkempt yards would also somehow find a way to break concentrations as widely as loud leaf blowers.
