Wind noise from mirrors?
« on: Oct 15, 2020, 01:29 PM »
Since getting a new helmet, I'm getting more wind noise.  I know this is more helmet related, but after much investigation, it appears the noise is hitting the sides of the helmet around the ears.  I've figured out following the airflow this is from the mirrors.

Any suggestions for rectifying this?

Thanks.

What mirrors do you have now?  Are those still the stock ones (hard to believe they lasted 11 years...   :008:).  Remove the mirrors and go for a ride.  If you can tell a significant difference, then it might be worthwhile investing in new mirrors.  Having changed mirrors (on a V-Strom) due to claims on some forums that they are a major cause noise and turbulence, I can tell you they aren't as big a contributor as some people claim.  That is, even with the "new and improved" mirrors, there still is noise and turbulence.  I solved the turbulence issue with a different screen on that bike. 

Anyway, you already know this change happened when you switched helmets, so the real root cause is helmet fit, not some change on the bike.  I realize it's a bit late to fix that, as it cannot be returned, but maybe you can fix the liner fit around your ears?  Sounds to me like the helmet is "rounder" than your head, which results in a gap in fit around your cheekbones.  Maybe a thicker pad could fix that?  Most helmets come in 2 or 3 shell sizes and the rest is done with different thickness foam padding.  Find cheekpads that are thicker than the ones that came with your size helmet.  That could solve it.

Do you wear earplugs?

The Aprilia mirrors (or their cheap clones) are often recommended for their aerodynamic shape, but keep in mind that they have a much smaller useful mirror surface area.


On the Versys I have these Bikemaster GP mirrors, they are a lot better at being mirrors than the Aprilia ones, due to their simpler and more rectangular shape:

Yes still the stock mirrors.  This helmet is actually a slightly more snug fit than my other.  However this is also a flip up, (applying to blood bikers so wanted flip up for in and out of hospitals etc).  So the cheek pads aren't quite as far forward, despite the inside being slightly smaller.

I was going to remove the mirrors for a test ride.  I've also got a second winter bike which is quieter, so yes the screen plays a part.    If I reduce the screen height I get blasted with chest wind.  If it's higher then I get helmet top buffeting.  The thing is, this bike is going to be used mainly for touring, so will be long days riding over several days, hence wanting it to be quieter.

Just wanted other experiences as I go through the elimination process.  (this morning was a scarf tucked inside neck warmer to add a buffer at the base of the lid against rising wind from body/arm deflection.

Yeah, weird one that. First time I've heard about mirrors as an issue for anything other than vibration distortion.

As a general rule, listen to Gustavo. He's quite clever.

Other things to check, most of which are very obvious so apologies if this doesn't help; do you have an intercom/camera attached to your lid? Mine makes an awful noise, so remove it as often as possible.

Also have a check on your visor. I spent months working with a very good lid but a really annoying whistle at a very specific speed range (55 to 75 mph). I hadn't quite fitted the visor properly and once it was fitted properly the noise disappeared. It was only out by a fraction of a mm, but it was enough to open up the seal on the right hand side.

If you have hand guards fitted; I was surprised how much they distorted the airflow. Perhaps they might be interacting with the mirror? Don't know, just trying to think a bit laterally.

yup, I do have helmet cam and intercom, wasn't an issue on the old lid with them. Might remove them and see as well.  Do have handguards as well....

My GOD, all my protective and useful stuff has to come back off???  :008:

Ear plugs are your friend.

My solution is to buy even more efficient earplugs. Works everytime for me - I have even found some cheap foam earplugs which really isolate me from the noise- from Screwfix!
