How about wind noise, aka the "silent killer?"

I recently installed a Dart fly screen on my Scrambler.

I always wear foam ear plugs when I ride. Noise reduction ~30 dB.

This web site ( ) says that wind noise on a motorcycle can reach up to 120 dB.

My files indicate that:

Gradual hearing loss may occur after prolonged exposure to 90 decibels or above.
Exposure to 100 decibels for more than 15 minutes can cause hearing loss.
Exposure to 110 decibels for more than a minute can cause permanent hearing loss.
At 140 dBA noise causes immediate injury to almost any unprotected ear.
So even with earplugs that reduce noise by 30 dB, if I'm on the bike and wind is at 120 dB, I'm still getting 90 dB at my ears. And for sustained lengths of time that damages my hearing. More than it already is.

Also, and this is the question re the Dart, I swear that the wind noise is now much greater than it was before. I'm 6'6" tall and have a correspondingly longer torso.

Have any of you noticed more noise with the Dart?

I won't argue with the article but I don't think I have hit 120db however I use a windscreen and have pretty quiet helmet....

Had my hearing checked a year or so ago.....even at 47 its still in the near perfect least thats what the doc said.....he was impressed it was still that good at my of the few things still working at factory spec.

Wind noise is different for each size of rider, the bike, the windscreen or fairing AND the helmet combined with the jacket collar configuration.
It boils down to how the flow of air hits you and then, what it does.

You probably aren't up at 120 dB but that is a WAG.

The decibel scale is logarithmic. Cutting the volume in half shows up as just a 3 db drop on measurement the scale. So if your helmet provides only an additional 3 db of noise attenuation and your earplugs give you 30 that drops the worst case from 90 db at the ear to 87, which is half the volume. That is why we see that only a small increase in the db means damage can occur in a much shorter time span.

Seriously, I always wonder about riders without helmets on straight pipe bikes. They must be causing themselves big time hearing loss.

If you do a lot of riding invest in a pair of custom made ear plugs. You can get them filtered to allow voice level conversations but block just about everything above that. Just about any hearing place can make them for you.

I've never had much success with any other plugs as they tend to work their way out from my ear canal, so I go with the custom ones.

i wear earplugs every time i ride . . . like a helmet , i wouldn't consider riding without them .

doing avalanche control , i detonate explosives on a regular basis in the winter time and have always been careful to cover my ears . we get our hearing tested every year and mine at 56 is still pretty darn good , just showing normal aging .

So much less fatigue with ear plugs. Custom ones are like $30 , I won't ride without them.

I think those decibel limits only apply with brain-buckets or no helmets at all. I have a modular helmet and have been riding without a shield on lately. Without plugs in I would still estimate that it's under 100dB.

For me, it's not the loudness, but the length. Anything over about a half hour at highway speeds I put plugs in.

Google "wind noise the silent killer" and you'll get a ton of articles about hearing damage and motorcycle riding. I thought it was curious as well but that's what "they" call it.

I can't ride without earplugs. Occasionally I'll forget to put them in, and when I get up to about 35mph, it just drives me crazy. Feels like I got in the shower and forgot to take my clothes off. I have to pull over immediately and put them in. I use the Hearos Xtreme with 33NRR. Only plugs I've ever found that are effective on my oddly shaped/oversized left ear canal.
