Used to live not too far from Brands. I'd only ever hear the 4's. I loved it though, sitting in the garden listening to the bikes across the fields and thinking "they're on it".
long wave low pitch noise travel further than short wave high pitch. give my back teeth for a local track.
In which case its odd how you hear an IL4 at high revs for longer than a V2. Although close up tye V2 always seems louder
Turn up on an open pipe Harley and watch them cry. Winds me up that we get "not for road use" stamped on a race pipe and pulled over by the plod, yet a Harley can chuck out more decibels than an earthquake and be considered fine.
I agree with Darko , maybe it's more a frequency issue , low bass appears louder than a swarm of hornets ..
Yet as bradders said you can actually hear a far away 4, far better than a twin. So... ducati defy the laws of physics... Another reason to ride red [emoji106]
thats long wave for ya. you can hear a jap coming. but ducs, and other good v.twins you can feel coming.
Welcome to my world guys .... The D16 only gets on track in Europe. The destinations do make for a cracking short break though. I've done Portimao twice) , Mugello, Misano, Magny Cours, Almeria and Jerez so far
I don't understand why it's so hard to grasp if being a little controversial here. Bikes are noisy... Panigales are VERY noisy... you either accept that or buy something else. Even with baffles they ARE noisy. Bikers are a minority and 99.9% of people don't want their day/morning/weekend ruined by noisy bikes just because they happen to live by a track. This is why most tracks run different noise limits based upon the day, so evenings are quieter usually... Just because we like the noise of bikes... doesn't mean others will.
Consider the noise when buying the house. You don't "happen" to live by a track that was there long before you moved in. Don't move in and then harp on about how you can't enjoy your garden on Sunday's because of the racing. No different to airports in my opinion. It just yells, "I want that house because it's cheaper than others of its size, but I also want the people who enjoy that track to stop doing so, so that I can have the bonus of a cheap house without the noise that made it so cheap". It's all I want, I want.
The answer is, of course, compromise. Home owners living near race tracks need to put up with some noise, bike owners need to minimise the noise their bikes make. Hence, db limits for track days, race days, etc. The limits are there: bike owners and manufacturers are aware of them. The only issue I would personally get incensed over is if tracks start reducing the db limits currently in place, either through the maximum levels or the annual number of days the maximums are allowed. That would represent an erosion of our current entitlements and is unacceptable. The fact that manufacturers are for whatever reason introducing noisier bikes, in these days where noise/emissions limits are increasingly being imposed on anyone wanting to have a good time, is a puzzle and the fact that consumers are buying these noisier bikes, is also puzzling.
I suppose the fact that they can "cheat" their way through noise & emission tests with flapper valves, doesn't help us lot at full chat at your local track
It's not always a choice. Sometimes circustances dictats where people live, buying a house 2 miles from a track shouldn't mean you get from 9am to 5pm of constant noise all day every day... I also doubt the councils change the policy of who's allowed what, when and how loud based upon 1 random person. I think it's pretty selfish to think bikes should be allowed to make noise all day every day just because bikers like it.
I see a lot of riders on here essentially blaming the actual circuits for the noise/dB limits and levels. Just to clarify, it is out of the circuits hands. They don't come up with the levels. It is the local councils. Circuits just have to enforce it because if they don't the track can be fined, or worse shut down. In the race controls there are monitors that record the drive by dB levels. Those records go to the council. If the council sees that we are not enforcing the noise they can fine the track. In addition, the static test is just a generalisation. It's the drive by that's most important. If you're not aware of it, the drive by meters are not on the pit walls or on the start finish line. Depending on the circuit they are around 20-30 meters away from circuit, so if you're loud when it's that far, well you're loud. FYI I personally work at one of th MSV circuits and I can tell you, we really don't care how loud a vehicle really is. We all work at the track because we all share a love and passion for Motorsports. It's just we have to enforce these rules so we don't get fined or shut down. We don't have any intentions to ruin you're day because your bike is to loud, but what you probably don't see is that on a daily basis our noise tester guy gets so much shite from the riders and drivers like its his fault, so sometimes he just gets fed up with and seems rude to you guys.
