Zitat von M3M im Beitrag #1 Honestly, after all these years of enjoying the quiet, I can't ride without earplugs. However, being a new owner of an Arai Corsair-X, I can say all the vents and the shield side covers do create more noise than my old Shoei's. But, the air flow and the fit is great. Try a scarf or kufiya loosely wrapped around your neck and tucked into your jacket. It'll function as a wind muff to minimize the turbulent flow noise generated between the bottom of your helmet and the top of your shoulders.

Excluding the significant factor of fit (i.e., the seal around the ear), the Arai shield pivot cover and latch mechanism are protuberances into the flow. As such, they will produce vorticity and tend to promote earlier transition to turbulent flow (i.e., flow noise). In that regard, the flush Shoei shield system is superior in my opinion. However, within the last generation or so of designs, Shoei has increased the size of their XL head shape to something that doesn't fit me anymore (too big) and I've migrated to Arai.

I have two Arai and they are very comfortable and have extremely good airflow...because of that they are very noisy with all the vents open. I have been riding with ear plugs ever since I started riding, so its like putting on a jacket for me, just used to it. I have been watching a lot of helmet video tests lately and it looks like my next helmet will either be the Shoei GT-Air II or Neotec II as they have tested the quietest lately with good airflow and still very comfortable. |

Zitat von Mr. 36654 im Beitrag #4 I've migrated the other way. Arai's visor retention mechanism is crude and noisy compared to the set up on Shoeis and HJCs. It always feels like you're forcing something. The Shoei also feels lighter than my Arai. It's strange, I spent the first 20 years of my riding career without earplugs, now I can't ride without them! |

Zitat von M3M im Beitrag #3 There is no generalisation about one make being quieter than another. Depends on the individual design. I have been a Shoei user for a while as they seem to fit well. My old XR1100 (RFxxxx in US) is not quiet due to the vented design. A friend tried to use one on a race track in a club event and had to ditch it due to the noise at high speed. My Neotec (original version) is quieter but still fairly noisy like most modular designs. Is there any reason why you do not use ear plugs? I know lots of people who have ridden for 3 decades who have degraded hearing as they did not wear ear plugs in their youth. |
Zitat von hyperm3 im Beitrag #5 For what it is worth, I have both the GT-Air 2 and Neotec 2. I find the Neotec 2 noticeably quieter than the GT-Air 2. |

Zitat von M3M im Beitrag #3 Your results will depend on whether or not the change you've made will impact the dominant noise source. If the noise source is in the internal flow passages, you'll likely impact it. If it is external to the vents, you may not impact it. Flow noise is a challenging field. As a result, most acousticians wuss-out and work in the field of structural acoustics (i.e., vibrations in structures)

Wear ear plugs, a lot of bikers have given themselves Tinnitus over the years by not using them, guess how I know. I got a tub of foam ones from a workwear store for pennies, a set of bluetooth plugs moulded to my ears and others. The only alternative is an open face and I'm guessing in PA in colder weather that's not an option. I have an Arai Tour X4 by the way. |

Using 2 helmets ATM the C3 Pro and the original Neotec. I find the C3 pro quieter than the Neotec then the Neotec has amazing airflow through the vents. I probably going to change to the C4 Pro towards the end of the year as from the review the C4 Pro has the edge over the Neotec II.

Zitat von M3M im Beitrag #13 depends on the angle & slope and how it helps air flow, surely? You see lots of steps and angles on F1 cars and aircraft. if you want a noise free helmet then you will need to wear a teardrop shaped one like the speed cyclists use but they will not be pragmatic on something worn for hundreds of miles a day as they will not have the vents, impact zones or manly appearance the consumer demands. A helmet is a compromise and the only way to find out which suits you best is to spend your $ and experiment. We are all pretty unique in our shape, the way we ride and our tolerance of noise. You will just go around in circles in a thread like this, creating more doubt. Whatever you decide, do reserve some $ for a pack of disposable earplugs as I have yet to find the Nirvana of a truly quiet helmet. Alternatively, buy a Goldwing and sit in a bubble of still air. |
