I am beginning to appreciate, again, the wonderfullness of sportbikes
and naked bikes. On naked bikes the turbulence is not a problem, and
on the sportbike I have now I will be lowering the windshield to get
my helmet above the turbulence and up into the clean air.
It would seem that the helmets with the tightest fitting flip shield,
and the smoothest outside shape would have the least noise.
Right now I have a Bell Helmet that has a poorly fitting shield. It
sounds like a T-37. (USAF jet trainer) The cooling vents up at the
top-front of the helmet make a lot of racket too.
So, I'd like to hear any suggestions about your experiences. Which
helmet has the lowest noise at speed?
Thanks for any info.

The difference is the new one vent so much better.
That's the trick, if you want it to vent, it's just noisier.
I can't give you a specific model of helmet that is going to be the
quietest. What is the quietest helmet for one person will not necessarily
be the quietest for another. What I can tell you, is that no matter
which helmet you pick, including the most expensive helmets on the market,
none of them are adequate to protect your hearing without earplugs.
See this post of mine from September 2002, it is still relevant:

quoting part of it:

I wear an inexpensive HJC CL-12 helmet and I think it is a pretty decent
helmet for a low-priced item. It is much quieter and more comfortable
than my old Bieffe helmet. I am sure I could find an expensive helmet
that would be more comfortable and a little quieter, but in the end it
all comes down to which helmet fits you, and you may find the quietest,
most comfortable helmet isn't one of the top-of-the line models. You are
just going to have to try on a bunch and see.
If you do decide to take up wearing earplugs, I can heartily recommend
the Howard Leight green Max-Lite style, they are only $25/box of 200
pairs from PK Safety Supply:
http://store.pksafety.net/maxdisearlpa.html
Make sure you read and follow the directions for inserting, it is very
important to follow the directions exactly or the noise damping function
will be greatly reduced.
At the rate I am (re)using them this box will last me about 10 years...

IMO, its a GOOD Quality one, but the key is finding one that fits your head.

Shoei's "X-line" is purported to be the quietest. My RF900 is pretty
quiet versus my old RFR. They keep getting better. Gonna buy me a X-11
prolly this summer. Then again, Shoei fits my head. Your head may
vary...

Lately, I bought a kit to make my own fitted earplugs. I think the
quietest system I have now is to have a short foam earplug stuffed way
in with the fitted plastic one on the outside.
Be that as it may, I am still looking for the quietest helmet. It
would appear, from my AE background, that the smoothest surface with
the best seal on the flip shield would generate the least turbulence,
and, therefore, the least noise.
It also would seem that one of the models with the little flipvents
all over the place would be noisier that one without.
I would sure like to see a complete test for noise done by real
testers,... test engineers, etc.

Sounds interesting, I am looking into having custom plugs made with
earphone inserts by my good friend who is an audiologist with a hearing
aid manufacturer.
Stuffing the earplugs all the way in is the 'secret' to making them work.
I was wearing them for years without knowing how to insert them correctly.
Once I actually read the directions carefully, the difference was
enormous, basically, I might as well have not bothered to wear them
for all the good they were doing. Yes, they were cutting down the sound
a fair amount, but nothing like the amount that inserting them properly
would do. Live and learn. I despair of getting my wife to understand
how to put them in the right way, she complains because they stick out
too far and bug her because they are rubbing on her helmet liner. I
roll my eyes and explain to her one more time, that if they are sticking
out at all, she hasn't put them in the right way, and they aren't doing
the job they were designed to do. It's still better than not wearing
them, but knowing that she is exposed to harmful levels of sound even
though she thinks she is not, bugs me a fair amount.

In my experience the biggest contributor to noise is a poor seal
on the visor, and vents aren't a significant factor.

The MCN test that I referenced was as professional a test as you are
going to find, IMHO.

I just dumped a Bell, for a KBC. It is a good deal quieter, but for
anything but short hops I'll still be wearing earplugs. Don't like that
ringing in my ears.

Quieter means better sealed. Better sealed means less ventilation on a
muggy day.
Arais are the loudest helmets out there. Once moving though you get an
awesome breeze. Sucks in winter though!

Hint: Close the vents! ;-)

SNARF! rotflmao..oh shit. You'd thinks those damn yankees would have the sense
to close the vents and warm up a mite. Sheesh...that state is cold year round.

Only bad thing is then they fog up. :-(
Mag
Not if you don't stop they don't. ;^) Now those fools who just ride around
town...well they have to leave the vents open year round if they don't use a
Fog City shield on their visors.

Buckle up. It'll make it tougher for aliens to suck you outta your car.
Maybe tie a knot in your neck. That's a good way to keep a head cold
from goin' to yer chest, ya know!! <bg>
now watch. some idiot is gonna waste a bunch o' bandwidth sayin' i'm
givin' folks (newbies) bad ideas, and i'm gonna get somebody killed. :(
Heh heh. That's really only a problem for the mouth breathers. LOL
Actually, the only time I have problems with mine fogging up, is when
I'm wearing a thick neck warmer and blocking the flow. I usually just
pull the chin spoiler down if I'm getting nippy.

For a second, there, I thought you were referring to a different

Thanks. I didn't want to be the one.
I wish. With the vents closed it still leaks like a Harley. I suppose
I could tape them up, but that's for candyassed NeoCons.

Hey, Chuckles, what the hell happened to yesterday morning. I didn't
get to see the dude. But I *did* run into one of my cub scout's moms
in Austin. Small world, eh?

Like I said, the Foreman decided he wanted to sleep in. So the Boss and
I figured we would not miss an opportunity and did likewise.
