I have hearing loss as well, and constant tinnitus, so trust me, I do know what you are talking about, but the motorcycle didnt cause it.
There is always someone out there who will complain about the sound level of your bike, or muscle car, or stereo, one mans music is another mans noise.
I dont know what you have for exhaust on your car, but even if its semi loud great sounding exhaust, its a good bet that someone has shook their fist at you as you drove by them

But I will agree with you on one thing, some bikes are REALLY loud, but then again, so are some cars.
