Re: loud exhausts save lives...
Not all the time but in some scenarios, particularly when filtering. I commute by car daily and look at the difference between standard cans and aftermarkets on the bikes coming past. Often I think people only move/look because they see I have.
The thing I see the most which still drives me facking insane is folded in mirrors, not only does it mean they can't see the bike approaching it means they haven't checked their mirrors ONCE since leaving their house to wherever we are...or don't care. Silent bikes and car drivers like that really make me worry. There have been instances on group rides where we've been doing a motorway section and have swapped leader to a louder can, just to get the traffic to part . There is definitely an increased chance of being heard.

I think most of the public just accept 'motorbikes are loud', there's no need to be hyper aware or worrying that you are annoying them. I remember people marveling at how far you could hear certain sportscars, not living far away from quite popular country roads we used to hear them a lot and guess what it was, never got annoyed. I think for most people fast/performance=loud and they accept that...what that has been proven to do is skew people's perception of speed which is my worry. If I'm on a bike with a loud can are people going to assume I'm screaming past really fast? Then imagine you are involved with an accident ; humans have a morbid interest in accidents, those people would probably bear witness that the bike was going 'way too fast' without really taking in anything other than the sound at the time it passed them and then piecing together the memories once they're aware there's an accident.

Re: loud exhausts save lives...
There are times I have used reverse psychology.
If I want to go fast I check the baffle is in. Why draw attention to myself through more reasons than necessary? |

Re: loud exhausts save lives...
There is some research into what we hear, what we associate it with in relationship to vehicles, etc. I don't think that I still have it, but will have a look, but I am sure that an Internet search will discover it if people are really interested.

Re: loud exhausts save lives...
Volume doesn't equal easier to locate.
The whine wop wop sirens of emergency vechles are a pain to figure out what direction they come from.

Re: loud exhausts save lives...
Nice post and a good find. I'll be sure to keep that study handy.
"Of course I wasn't speeding Officer, my v-twin is just a bit noisy" Seriously though it does give grounds to discredit any witness that says you were going too fast if your vehicle is noisy, thereby levelling the playing field once again. I may not be a good example of the average Joe, having obtained a degree in Sound Engineering.

Re: loud exhausts save lives...
the lower a note becomes the less directional it is. white noise is a fantastic directional noise that humans can hear where the source is. low frequency bass note on the other hand and you are less likely to hear the source, get below 30hz and you have no chance hearing where its source is.
i often wonder why they dont incorporate white noise into emergency vehicle sirens. |
