+1 on this.

And I'm not talking about Sportsters with drag pipes......my EV with Lafranconis  or Superhawk with V&H were both loud enough to make the long legged forest rats move away from the road.

Though often when startled they go towards/across the road too. May depend how the noise travels or echos.

Same with loud pipes on the 405.  I hear them, but don't know where they are.  If I need to change lanes I put on my turn signal and they better be paying attention.

Loud pipes were never meant to save lives...they were meant to annoy others, same as unnecessary throttle blipping at a stoplight...if it annoys others around you...mission accomplished.

Yup............ that pretty much covers it.

If you've ever tried to get to sleep in a French town or village, when the local 15 year olds are showing off on their 50cc mopeds you'll agree that loud (or non-existent) pipes make you want to take lives.

No, cold shrinks.....Notice I said open pipes...Sporty sounding mufflers on a bike ridden with common sense in built up areas isn't annoying....

The problem is thatís one persons opinion. Noise levels and what is acceptable is a very individual thing.

  Yes, and when your noise offends me, you have now forced your opinion on me..In reality I pay little attention to most excessively noisy vehicles going down the road...

This conversation is a good indication of how the history of written laws and the enforcement methods of those laws came about. Simply answer, comment sense and respect for others or the lack of abounds.
Just an observation:)

It's also a question of where and when. I love the sound of a bike winding through the gears or signing at redline - on a race track. Not so much at 11pm screaming down a nearby road or the blipping of open pipes in my ear at a stoplight.

Bought my Griso with a 'custom' open pipe that sounded pretty cool at idle but could not be ridden on the road without pain - even with earplugs. Not sure what the PO was thinking but it turned a glorious bike into a loud obnoxious turd. It wasn't  the Guzzi 'sound' we love - just noise.

The selfish and inconsiderate few upset the masses and we wind up with blanket laws thrown at everyone. A little respect and consideration for others is all that's needed.

And the individual who believes open pipes loud enough to damage the hearing of those beside him is acceptable is a selfish immature needy jerk in my opinion.

But it begs the question...what is loud? I have friends and/or family who are darn near deaf and others who are noise sensitive. What dB level is irritating or tolerable?

That, my friend, is the right question. There is no right answer but it won't stop one side from trying to impose their collective will on the other.

120 dB and above is unsafe for any period of time. A short burst at 130 dB can cause permanent hearing loss.

     It's not just the loudness that causes damage for me. The low rumble of a guzzi or similar engine has to get quite loud before I find it unpleasant.

     For decades I never wore hearing protection while using a variety of equipment and machinery (including motorcycles), that changed when I started using little 2 stroke powered whipper snippers & brush cutters a few years ago.

     The higher pitched scream of those smaller 2 stroke engines, literally caused my ears to ache. I realized at that point my hearing was a finite commodity and started wearing hearing protection around all machinery, including my motorcycles. Preserve it or lose it.

The sad truth is that it does not take that high of a decibel level to damage our ears and causing ringing or tinnitus. I ruined my ears years ago at the firing range simply by forgetting to put my hearing protection on for just the first round, a few times over the years. Whatís too loud on a motorcycle is when your buddy wonít ride near you on a road trip🤔😂😂😂

I think most campgrounds want invertor generators under 60 db. Good rule for motorcycles too. Of course they also restrict the hours so no more nighttime riding either if we follow that rule.  yes sarcasm.

Another data point to my study, ready to pull out of a pull-off on the side of a Tn mountain and luckily I heard him in just enough time to stop pulling out, otherwise I'd have Kawasaki green all over my blue Chevy truck. His loud pipes definitely saved his ass on that one. He was well above the posted 25mph so it would have been nasty.
