Screens and helmet noise?

[Maha]

Perhaps alter the angle of the screen?

Exactly...its what I did, I have the same size screen and my head is still, even at around xxx kph
I would suggest to tilt it forward a cm or so , wont need much.
I dont, never have and never will use ear plugs.

[nzspokes]

sound strange to me.

what kind of plug are u using?
nrr?
are they worn correctly?

i suggest you to buy a pair of silicon mould plugs...

Just foam ones. I read an old thread on the mould ones so may try to find someone to make some.

I think ours are the same, mine is right forward. What Ive just done rather than take it off is drop it back. About to try it out...

Interesting. I am the exact opposite - won't ride without plugs. Without, I hear all that mechanical noise from the engine - sounds like it's falling to bits...maybe it is..? :

I find the plugs dull the engine noise but it is still hearable, but boy do they cut the wind noise so the ears don't get tired and I can still pick up changes in the engine note.

There is a technique for fitting foam ear plugs, get it wrong and you may as well not be wearing any.

There is heaps of info about correct fitting.

3M have a U tube video that can be found by searching " fitting foam earplugs"

Wont cure the buffeting though, but it will stop you doing damage to your hearing. Lots of deaf motorcyclists about, don't be one of them.

Good to see you on the Shelly Beach ride last Saturday too.

I'm looking at wearing ear plugs for longer open road rides but am curious as to why you don't wear them Maha.

I also recommend that 3M you tube video. Changed the comfort and effectiveness of my foam plugs once I stop trying to just mash them in my ear and fitted them properly. Doesn't take much longer and they don't fall out.

[NordieBoy]

I can't ride without plugs.

The bike sounds too "falley aparty" without them.

Was good to meet new people out there.

thanks for the U tube link. Yes I have been doing it very wrong. Will go get some new plugs and try that out.

It's the screen. I am yet to use anything but a very small fly-screen that DOESN'T make a gawd awful racket - regardless of angle, its height, helmet, ear plugs - or bike.

The taller you are the worse it is. Easiest solution is to remove the screen. I simply hates 'em.

[Devil]

Yes, I agree with Large David. It's usually the screen, particularly if there's vibration involved. VStroms are terrible for it (as an example), my current bike has a fantastic screen though, no buffeting issues for me.

[Big Dave]

no buffeting issues for me.

You are 'small' enough to fit inside the bubble it creates - for a tall guy to do so needs a screen so big it impacts on the handling of the bike.

Best to lower the level of turbulent air so it hits as low on the torso as possible.

simple question: why?


my answer at yours:

you're wrong.
from the Cost 327 report: "the noise level on a bike is well sufficient to result in hear damages".

noise levels in a helmet have been measured at a mean of 90 dB at 65 kmh, 96 at 90and 120 dB at 160kmh.
two hour exposure at noise levels higher than 96 dB are above the large part of job's safety regulations.

the problem is aerodynamic noise.
starting from 20 kmh the engine noise is mixed with air's one, which become the higher at 35-40kmh.
fairing do not help, at least not for sure, as it's not completely possible to calculate the way fluxes impact on your torso and lower head after the end of the fairing, and how they interact with the helmet. in some cases it seems that there is a higher noise with the perturbation induced by a fairing than in a helmet put in a clear airflow on a naked bike.
obviously a full fairing well around your shape helps, so on a k1600gtl i'm pretty confident you'll have no aerodynamic booms around your ears...

now your point is (i suppose) "i don't hear the street around me", and that's your fault.
McCombe (1992) and Binnington (1993) reports state that "below 50-55 kmh the alert sounds recognition is found to be better without plugs", but "above 64 kmh plugs help in street noise and alert sound identification."
As for the Cost 327 those results "confirm what have been found in various industrial environment studies".

so the advice is: wear plugs.
have your silicone done and keep them in the jacket.
within the city, below 50-60kmh and for short trips, you can handle it alone.
above that speed pull over and put those plugs in your ear...

Which helmet did they test with?
