...So Ur in school to get Ur PhD, and U have a class in H.F. & Ergo. So I'am thinking the safety and warning must be in the HF side of the field and not Ergo..
So how Much noise is necessary to be able to be called a warning system
without too much noise to be considered it as a nuisance or damaging one's hearing, and still be considered safety...
The more I think about this, its one weird study...By that I mean how to obtain information.

You're question about how much noise is interesting and I don't know the answer to it. I find firetruck horns and train horns pretty annoying, but they were designed to be that way - to grab your attention and not let you tune it out. With pipes, the goal is not to be annoying, but to sound good and hopefully alert drivers. I'll have to think about that some more.
Obtaining good data mainly depends on how well the experiment is designed, and what statistical analysis is used. I'm sure this will go through several iterations because you're right, it can be difficult.

Using pedestrians or people sitting at a cafe would be interesting - that could help answer the annoying pipes question. If I find a certain range that effectively alerts drivers, I could then qualitatively test how annoying it is for people in homes, or walking down the road.

...it seems to me that this is more a study in a drivers reaction to sound. maybe checking out something about how they come up with the different sirens that they came up with might be interesting...
...and just an additional thing that might be added would be the location of the motorcycle to the car. obviously the bike coming in the opposite direction is the most dangerous, etc. then being next to the car...

I foresee managing the location of the sounds as a one of the more difficult aspects of the study. I'll definitely need to consult with some people when I get to that stage.

To be serious for a minute though, the study will not be designed with a clear bias - that's kinda like saying someone is cheating or stealing, and though it's obvious you can see the future, you don't know me that well.

I have loud pipes. I like the sound. Im not delusional.
Unless we start facing them forward we are kidding ourselves. Since the sound is directed back we aren't warning anyone but people we have passed. Lol or the dumbass ont he cell phone beside you.
Emergency vehicle sirens have been studied to death. There's a reason the sirens face forward and even then they have limited usefulness as cross traffic and distance/speed all impact the effectiveness of the siren.

Which is the one exception to the "loud pipes save lives" argument I've come to recognize as possibly credible but I still don't think it's worth it in the long run considering the ever increasing crackdowns on noise that we're reading about across the country.

As a 24 year line fire fighter, I can attest to the fact that the sirens usefulness is far more limited than the lay person would ever imagine. It's amazing, and frightening, how close we get to some folks before they ever react to the noise.

I know my pipes are way too loud and as such i avoid areas i know are being targeted for street racing/noise/EPA ect. I arrive home from work at midnight and try to coast along at an idol to not enrage my neighbors.
Next bike will have quieter pipes as between the loud pipes, wind noise and resulting ear buzzing a damn Fire Engine took 5 yrs off my life with the air horn last week.
