Quietest helmet
« on: August 29, 2015, 03:30:07 pm »
I want to get a new helmet, and alhough I like the good looking ons, it's no longer my biggest need, the awful noise inside my Shark helmet is!

I've been doing some Googling, and it seems that Schuberth are known to make the helmets which measures the lowest Decibell value.

Can anyone share any insight on this subject? Or offer some advice?

Get a Harley...then suddenly you won't even hear your helmet! Ha ha

Shoei Hornet is also good. Adjusting your screen angle/height, if possible, makes a lot of difference. The helmet's peak obviously makes the noise worse.

Strange - I find the hornet noisey - I have nothing to compare it with, except for off-road helmets - but the wind is pretty loud in there.

Don't think I'd buy another one

Yes, that's what I've been looking for. I've been sold a Nitro and an Aria on the promise that they are quiet and they are like standing behind a Boeing on takeoff. However, recently Grant Umpleby's side kick Joe sold me a helmet on the promise that it was ultra quiet. It was dirt cheap (less than R1000) and I bought it because it was so comfortable but it is really, really quiet. Closest to an anechoic chamber that is also a street legal helmet that I've found so far.  It is an HJC and the model appears to be CS14. Having said that, a great deal of the howl is from the gap around the nape of your neck and how the padding fits around your particular shaped head. I think I am a pretty regular shape though. Ian

That and the looseness of your jacket - it can make a huge racket around the shoulders/chest and back.

Understand a few simple things , everyone has a different shaped head and certain helmets fit certain heads better than others , for me personally Arai could have used my head for a mould and Shark and Nolan are both a good fit , Shoei and AGV on the other hand do not fit me well at all .
And then once we have decided which helmet offers the best fit , most people go for a helmet that is a comfortable fit , and that is also a mistake , generally a good idea is to take a helmet that is slightly uncomfortable and will be so for the first few times it is worn , generally after an hour or 2 of use the helmet lining will compress to the shape of the users head . Now bear in mind that the lining on a helmet that is a comfortable fit will also compress and then the helmet will become a loose fit , which is also not comfortable or quiet .

And of course there is also another factor and that is the bike and or fairing /screen on the bike , I have ridden bikes where my helmet has been beautifully comfortable for 800km , then ridden the same bike with a touring screen and after 250km the noise was unbearable because the touring screen had channeled the noisy wind directly onto my helmet whereas with the stock screen I had clean wind on the helmet . So at the end of the day the noisy helmet might be something other than a bad fitting helmet .

As they said, EARPLUGS!!

Much cheaper than a new helmet and your ears will thank you later...

Visit the "Ear Instute" for custom molded ones.

Shoei GT Air - all the reviews on the web are indeed true, not only the quietest but also the best lid that I've ever owned!

If anyone grew up, like me in the 80's/90's then you'll remember Barney Simon on 5FM's famous saying:

"If it's too loud, you're too old!"

Just kidding bud.

I suffer from Tinnitus, a constant ringing in the ears probaly from abuse when I was younger, but after riding wihtout earplus the ringing gets really intense for a few hours afterwards, wish I looked after my ears better when I grew up.
The more shit is on the outside of the helmet, ie vents, peak exposed screws etc the noisier it will be. i don't think we are going to find a DS helmet with a peak that can compare to a Schuberth road helmet though, but then we go a LOT slower than superbikes on a breakfast blast.

I use earplugs. You can buy tonnes of them for cheap cheap from a Builder's Warehouse. My hearing is valuable to me. Here are some interesting excerpts from an article that motorcyclists are at particular risk for permanent hearing loss:

Quote
Based on several research studies, the major contributor to hearing loss in the motorcycle industry remains the "silent killer" known as "wind noise."

Quote
if this issue is not addressed correctly from the beginning the amount of exposure to the inner ear is compounded every time the rider ventures out on his/her bike for hours at a time

Quote
To put this in perspective, according to OSHA's regulation of industrial noise exposure, an average worker surrounded by levels around 85-90dB for an eight hour day will not exceed the limits of exposure time within a 24 hour period of time.

However, when the sound levels exceed 100dB, your exposure time is reduced to two hours. When sound levels exceed 115dB, your exposure time is drastically reduced to 15 minutes. This puts riding a bike a whole other realm as "wind noise" at highway speeds can measure up to 103dB, or comparable to a running chainsaw. At these levels the rider is not only fatiguing physically from the excess noise exposure, but it also puts him into a position of needing a hearing aid later in life.

Quote
Riding position and style of windshield help in preventing "silent killers" ability to fully be experienced. But even the best helmets on today's marketplace provide little help when considering "wind noise" levels at normal highway speeds. Obviously, this factor is increased in half shell models as well as skullcaps, but the common helmets used in today's marketplace are designed to fit entirely over the head providing a snug fit. These types of helmets have the best attenuation value (reduction in noise) regardless of any airflow modifications done to the outside. But these helmets still produce wind noise readings of 110 to 116dB's, from 35mph [56 kph] to highway speeds. When reflecting back to the comparison chart, 116dB will only be suitable for 15 minutes of riding a day. Not a lot of time to enjoy your hobby.... Is it?

Quote
There is no significant difference in wind noise level as a function of speed, no matter what the helmet brand or model (all being full coverage).

Quote
Below 30mph [48 kph], machine, exhaust and environmental noises are heard. Once speeds exceed approximately 30mph, wind noise dominates completely.

Does the Ear Institute do the trick, Ratel? At the last count user - specific ear plugs were about R1000.

I went and fitted a number of these at Spirit. The XL size, their largest, was way too small for me. I tried their Adventure bike and roadbike range. My normal helmet is an Arai in XL and a Bell M1 (also XL or 61). These fit me like a glove. As others have said, try them on for size first. My guess is that they are sized for Chinese or similar peanut sized heads :ricky:

Yep for sure. I bought the No Noise plugs and they hurt after a few hours. The plugs made for you is the way to go,can wear them for hours without discomfort.
There is a chick in our Harley club that does it. Takes the moulds,then a week later you get your plugs. Cost is just under or just over R1k . Worth it I reckon.
