Oh noes, you didn't just science the stupidity did you?
I am not claiming that they can not be heard from in front of the bike.
You stated that a motorcycle exhaust is "omni-directional" which is factually not true.
Sound pressure is directed primarily in the direction of the exhaust exit. The amplitude of pressure waves will be highest when measured coaxially in relation to the exhaust exit. Higher amplitude means louder. They are not "omni-directional".
Comments like this in this thread give me a headache... continue on!Because deaf people, like blind people, tend to use their remaining senses better than the rest of us...and it's not a critical sense (like vision) that makes them unable to operate a vehicle.
However, if one day they suddenly HAD hearing again I think it would be naive to suggest they wouldn't once again use that sense to listen for things again while driving.
I said they're "basically" omnidirectional meaning that for the sake of this discussion they can be heard from all directions and orientations. I made no claims regarding intensities. As an electrical engineer I've referred to and used certain "omnidirectional" antennae which typically have torus ("donut") shaped radiation patterns:

Despite the radiation patterns not being perfectly spherical these antennae are still referred to as "omnis".
Given this precedence I don't feel my use of the term "omnidirectional" to be egregiously in error. But if you want to pull out your SPL meter and map out the lobe shapes of various motorcycle exhausts as you pick the flyshit out of the pepper be my guest.
Perhaps you could put that acumen to use to address those that claim that motorcycle exhaust noise is useless as a safety enhancer because it all goes out the back. Failing that, I'm sure there's some grammar or spelling somewhere you could attack next.
So what? There's no assurance or expectation that any of our conspicuity measures -- hi-viz, modulated headlights, auxiliary lighting, loud(er) exhausts etc -- are going to catch the attention of all drivers but if it catches the attention of even one guy about to lane change into you then it's worth it.
I don't know why people have to make things "all or nothing" deals; loud pipes won't catch the attention of a 16 yo moron ergo loud pipes are useless. It's a fallacious argument.
I guess the 48000km on my Vstrom since June 2013 and the 6000km on my DRZ since Sept 2014 were all done just circling Square One one lap at a time.
Didn't you post a pic of you and the gf the other day? Based on that alone, then yes, it was the bike's work.Any data to support I ride a motorcycle to get chicks and be cool?
Cause this thread sure demonstrates why the ladies love the guys who ride.
Comment is gender bias due to the lack of female participation but, I would imagine the same holds true for either male or female riders.

This makes sense to me. In my warehouse, all of our electric pallet jack machines used to have a constant beep when they were in motion. ~50 at any given time. People used to come in and say "how do you deal with all that beeping?" My reply? "What beeping?". Now that I have trained most to use their horns when backing up, approaching blind corners etc. incidents have decreased.Do you have your horn button shorted out so the horn sounds all the time you are riding? If not, why not? After all, isn't it worth it if it catches the attention of just one person who might not have got the message from your loud pipes?
What happens when EVERYONE, car and bike alike, go to loud pipes to gain that bit of a supposedly protective edge?

...making yourself look more silly by arguing semantics.
If only you could do the same with the loud pipes. So I guess you agree that loud pipes make a lot of unnecessary noise if the extra noise is really only needed a fraction of the time?If all that fails, I have the horn as a final back-up, if you will, that might get their attention on an as-needed basis.
I was sitting at the forks coffee shop yesterday talking to a new friend (Iceman) bikes coming and going the whole time. If any silent bike rode past I don't know about it. There were at least half a dozen bike where the conversation needed ceased because the exhaust (and one with loud stereo no guff lol) was over the top stupid loud. Just saying.
I don't need to. My exhaust provides a certain level of sound that, when combined with other things like hi-viz and "careful" riding goes a long way to ensuring my presence is known to other drivers. If all that fails, I have the horn as a final back-up, if you will, that might get their attention on an as-needed basis.
Then I'll have to go a bit louder I suppose. Yours in an interesting but useless hypothetical since cars and motorcycles have been around for more than 100 years and we've not had a noise-level arms race thus far.
It all goes to reasonable levels of sound. You guys are so fixated on the open-pipe fringe case that you're blind to the obvious benefit of reasonably engaging another of other drivers' senses for your own safety.

Thread title is too confining limiting discussion to loud vs quiet. Need happy middle ground. Is this doable?
