Shoei XR1100 wind noise.

anyone else with this lid thought there was a little too much wind noise? well i did and stumbled across these

Looking into it seems the recess for radio speakers etc. causes wind to swirl around. got some of the above pads and it has greatly improved it. in truth you could probably get away with sticking a bit of foam in the hole.

I made up similar ear pads for my Arai but I've added some small passive noise-cancelling speakers. Volume wise they're pretty loud and do cancel out a lot of wind noise. The hardest part was getting them the right distance from my ears. To close and they squeeze your ears. To far and the volume drops. I used thin layers of sponge and made up some sponge shims to get them at the right distance.

Now whenever I go on a long run I rock... But I knew that anyway.  :lol

There's an extra jack plug on the lead if I want to add power and make them active but so far I'm pretty happy with the results.

Did you do something like this KK?

Very similar except I didn't have to cut up the speaker housing. The speakers I used are from 'On the ear' headphones and are about 35mm diamiter X 15 mm deep as opposed to 'around the ear' (as in your link). I did have to dissmantle them but only to remove the steel head band.



When the power jack is turned at 90 degrees the earphones operate in passive mode. The power for the active noise canceling is supplied when both jack plugs are in a paralel position, however if there is no power the speakers go into a mute mode so I use it as a quiet switch as there is no volume control as such. It usualy gets pluged into my iPhone via coiled extension lead. The batteries connect to the other jack plug via a different lead with the two cell battery pack velcro'd to the helmet.

Can't hear that much difference between between the passive and the actice though. If anything I'd say the actice was better at lower speeds.

ok.. urinates all over my little addon lol

A quick warning: as I discovered a couple of years back, some cheaper headphones on eBay that are advertised as noise-cancelling are nothing of the sort. Instead of using a microphone to try to add an antiphase signal to cancel external noise, they just have a cheap amplifier to make the music a bit louder... completely useless in this application.

Awesome....just bought some, thanks for the info.  Mine's a Quest, but has the same cutouts.

Yay, glad I was of use to someone lol.


The whole noise cancellation thing does worry me a little. surely your ears are still subject to the movement of air therefore moving your eardrum. Just because the noise has been cancelled out electronically does this stop long term hearing damage?

I think I will stick with earplugs and in-ear phones for music and satnav.

cheers though

From a physics perspective two standing waves that are of the same frequency and amplitude but 180 degrees out of phase will cancel each other out to cause 0 noise. So proper noise cancellation (even electronically) shouldn't damage your hearing at all

yeah i am aware of the physics behind it but my point is that just because your ear no longer hears the noise does it mean it is no longer subject to the pressure wave? after all on a plane you still get the popping sensation in your ears.
This is turning into one of those "if a tree falls in a forest" questions lol
Anyway after looking at the guide above it does not do a great job of canceling out wind noise so i am happy with my £5 fix haha :lol

Electronic cancellation of the noise will only occur within the headphones' frequency range. Very low frequencies will be outside that range... unfortunately the noise produced by air thundering across the base of a crash helmet at 90mph does contain a lot of very low frequencies.
Then again, earplugs have a hard time filtering those out too.

Of course, but the cancellation technology is cancelling out noise. The fact that it can't cancel out frequencies out of its range bears no impact since without the tech you would be exposed to them regardless. I was mostly pointing out that using the technology wouldn't cause any additional noise on your ear and would in fact reduce it.

Also the reason for your ears popping on a plane isn't the noise, its the altitude and pressure. Noise cancellation for headphones will decrease pressure (due to cancelling the waves) - at least within its capable range
