How can I stop whistling in my helmet?

[Srengam]

I bought myself a (albeit cheap) helmet, (I've been using a borrowed one).

But it whistles, It's got three vents which I have closed but it still whistles, are there any tricks of the trade to stop it?

Cheers.

If it's cheap you probably can't take out the liner and tape up the offending vent...if it the vent.

Glad to help.

Are you wearing earplugs? If not, get some.

My helmet is a whole lot quieter when I wear a big chunky scarf. Stops the wind getting through under yer chinny chin chin.

While it's whistling move your hand in-front of your helmet and see what position the whistling stop, this should give you an idea as to what is causing it. Then fix it with either tape or as I used to stop my intercom whistling blu-tac.

Visor position can affect the wind and so the noise.
Also any screen fitted to the bike can help.

Just as long as you don't hear voices in your head!

That's what you get for buying cheap rather than a decent helmet, but you've learned now from your mistake and what brands to avoid in the future due to poor quality of workmanship and material.

Its whistling due to the airflow over your helmet. You're going to need to alter that airflow in some way to stop it.

You basically need to start playing around with the way the air flows over your helmet, and try to find out where the problem is. A simple way is by holding your hand in front of different places on the helmet to disrupt the flow. But its going to be a totally trial and error process.

Even if you find out where the problem is, the solution will be equally trial and error. Maybe you'll get lucky and its a vent/projection/gap you can stick some duct tape over. Changing/fitting a screen can cure whistling sometimes, and in other circumstances, cause it.

TL:DR - Potch about with it.

Headphones, shut all the vents & visor & if its still shit make a mental note to check the reviews of the lid before purchase.

Ear plugs work well, get some decent ones. You could try putting a bit of extra foam in but that tends to pull the ear plugs out

[Srengam]

Thanks all,

I found the neck warmer worked a treat, only a slight whistle gets through every now and then. It's the rear right vent that's the offender, I'm gonna look at taking it off and putting some gaffa tape underneath it.

I had a shoei xr1000 and a shoei XR 1100 - the XR1000 was horrendous for wind noise . My Suomy helmets are a bit quieter, but not by much. I dont care, i wear ear plugs or headphones when it bothers me...
