It is. Every second, no, but 100,000 times more than a man mowing his yard. Like I said, there's a known time limit on yard mowing, and you know you got a week or two break in between. Try having a Sunday grill out in town, and it will be barking dogs, rap music, and loud bike exhaust every few seconds.
Are you unable to address the offenders and ask them to stop?
FWIW, a few years back, one neighbor within hearing distance complained about hubby working on bikes late at night so now we have a strict 10PM cut off time for any motor related testing.
Perhaps you have only to ask.
