Wind noise in the case of motorcycle riding is the noise produced by the hitting of wind with the helmet producing vibrations responsible for high-frequency noise.
This noise at highways can seriously affect your hearing causing permanent loss, so you need to protect your ears properly.
At the fastest speed, wind can produce noise as high as 115db into your helmet. Repeated exposure to even 85db can seriously affect your hearing and can make you lose your hearing permanently. 115db is 8 times the threshold where you can lose your hearing. For comparison mp3 at its full volume is 105db.
For hearing loss, not only the volume but the time of exposure is the factor too. If you are exposed to noise for a shorter period it can bear the high volume but for longer periods you need a low volume sound. More time and higher volume, THE WORST combination. Therefore, you need to reduce this wind noise to keep yourself healthy.
Wind noise not only causes hearing damage but also causes fatigue and weakness. You will notice after longer rides with no protection you will be exhausted. Fatigue is another danger for health itself.
The ringing sound in the ear after prolonged exposure to loud noise is called tinnitus.
You will not notice hearing damage instantly, tinnitus is you can say the first stage, these small incidents combine to make a big loss.
CAUSES OF WIND NOISE
● FLOW AND DIRECTION:
Not only riding wind but side winds are a hazard too.
Speed is a factor for producing wind noise but the flow and direction of the wind contribute more. With flow, we mean that when we ride a bike on a road with minimal traffic the wind is clean, it has fewer things to hit with, which means less
wind noise, more clean wind, and less damage. But when we drive near a big object like near a truck we notice a loud wind noise as the wind now has more and bigger things to hit and produce turbulence causing louder wind noise and being a source of damage.
Turbulence is the irregular flow of the wind.
The best flow of air with a minimal turbulence is around a drop of rain, so bikers try to copy the shape to have minimal effect of turbulence.
Making the bike as aerodynamic as it can get, but we can’t get that perfect shape of a raindrop so maybe turbulence is something we have to live with but there are methods to reduce the damage.
Windscreens on a bike are a source of turbulence too. As there is space between the screen and the helmet thus producing irregular flow and turbulence making wind noise louder.
Buffeting is a kind of turbulence. It produces high-frequency resonating sound by hitting the helmet, thus even shaking the helmet and producing blurred and extremely uncomfortable riding.
Thus, in conclusion, the following are the biggest factors of wind noise:
3. Riding position
4. Helmet design
5. Motorcycle design.
WAYS TO REDUCE WIND NOISE:
The Simplest ways to reduce wind noise are:
❖ Right Helmet:
A helmet that fits you correctly, always consult a helmet size guide to get a helmet. A Correctly fitting helmet isn’t just providing you with safety but also making your ride peaceful by reducing the wind noise.
Other than size there are helmets with more padding to keep you safe from the high sound on helmetsavvy.com.
And some are more aerodynamic In shape providing minimal turbulence thus less wind noise.
Another thing you can look for in a helmet if you are a beginner; is if it is open-face or full-face.
The Full-face helmet is more noise-free and comfortable. And they also provide safety in case of a crash.
The last thing you need to look at is if you have a helmet that has a visor, always keeps the visor down, to maintain the turbulence and less wind noise.
The thing you need to look for in a windscreen is its shape. Windscreens that are aerodynamically shaped produce less wind noise.
Next thing is to skip the windscreen; riding a naked bike will provide you with minimal turbulence and minimal wind noise.
▪ Add accessories:
Some accessories can provide a quieter ride.
First, a scarf, you can use a scarf to cover the gap under your helmet so less turbulence, more safety.
Second, earmuffs are a popular choice to consider too.
Third, face masks cover your face and neck and cover the gaps and will keep you safe from dirt and bugs too.
Fourth, earplugs can be used to keep you safe from excessive noise. Buy some quality earplugs that can fit under your helmet.
HAVE A SAFE RIDE!
