Hello thanks for your answer !
Yes definitely this is the wind that is the most loud thing when riding... Because my Motorcycle is a brand new model with really not a loud engine, I couldn't ride something too loud anyway ! LOL
Do you know the brand of this Helmet ?
The helmet in question is the Sena Momentum INC helmet. In my opinion, don't bother. Sena has missed the boat on this one. Fantastic concept, but it all ends there. About a year and a half ago, I came down with Tinnitus and freaked out...thankfully, short term. I thought my riding days were over. After a number of months, I decided that riding was just too important to me, so I started on a quest to minimize the risk of (further) noise-induced hearing loss. I researched motorcycles, motorcycle accesories (wind deflectors, etc.) and helmets extensively. I sold two of my beloved motorcycles(Harley Ultra Limited and a Honda Shadow Aero), because I thought they would put me at greater risk for worsening T (I now believe this was a little impulsive and unnecessary).
For a motorcycle, I bought a BMW R1200RT (supposedly, one of the quietest in the industry) and bought a Schuberth C3 Pro and later on added a Shoei GT Air (both highly rated in terms of wind/noise protection. This set-up made me comfortable enough for me to continue with riding. I had previously ridden a number of across the USA trips and was still skeptical about long distance trips. Since then, I have ridden from Massachusetts to Florida and back, as well as a cross-country from California back to Mass. I wear earplugs 100% of the time and I believe with a diligent, sensible approach to wind management, I can continue with my passion.
Back to the Sena INC helmet. I bought one right after they came out. I thought it would make the use of ear plugs unnecessary. I did head-to-head tests with the Schuberth, Shoei and Sena (all in the same day, under the same circumstances). Although the Sena might be an "okay" helmet in general, in terms of what it claims to be Intelligent Noise Control), it is a piece of garbage that lays idle in my cubbie.
As far as your decision to ride, that decision is yours! We can't erradicate risk, only minimize. For me, it comes down to passion and what I'm willing to do with that. I LOVE motorcycles!
