How to soundproof a motorcycle helmet?

In this blog, we will go through some of the best ways to reduce helmet noises. With these methods, you will enjoy your long and high-speed rides.

Nothing destroys the thrill of driving down the highway on a motorcycle like ear-piercing noise. While most helmets are supposed to be soundproof, not all helmets are created equal, and it’s not uncommon for a rider to find up with a raucous helmet.

The noise inside your helmet might exceed 115 dB at fast speeds. And that would be just the wind sounds. When other traffic noises are taken into account, the total noise level rises. When this occurs, you’ll have to take action to lessen the noise, which might be difficult if you’re unfamiliar with motorcycle helmets.

Hearing loss begins when you are exposed to noise at 85 dB, according to studies. Hearing damage is more likely in riders when the decibel level exceeds 115 dB. This explains why every rider should always use a quiet helmet.

Aside from the risk of hearing loss, riding in a noisy environment is quite unsafe. It is exhausting to be in a setting where there is a lot of noise. This is the absolute last thing a rider requires. The trip becomes more enjoyable when the helmet is quiet. All noises can be reduced to below 85 dB with the right helmet.

These are some soundproofing techniques for your motorbike helmet to help you reduce noise and enjoy a more pleasant ride.

  • Choose your helmet wisely 
  • Get a well-fitted helmet 
  • Wear a Wind Blocker
  • Earplugs
  • Change the Riding Position
  • Invest in a Scarf/balaclava
  • Make Windscreen Adjustments
  • Ensure You Have a Well-Fitting Visor

Choose your helmet wisely 

The noise reduction capacity of different types of helmets varies. So, if you’re having noise issues with your helmet, the first thing you should do is replace it.

The air will move through each design differently, changing the sound you hear. When choosing a motorcycle helmet, the priority should be to find one that can withstand impact in the event of a bad accident.

Aside from that, you can select ones that aid to reduce noise. You can also do something about the noise if you find a helmet that you like to wear on your motorcycle but might use additional soundproofing.

Any open-faced helmet, including “skull caps,” will allow the majority of turbulence noise to pass through. This also applies to helmets with a three-quarter face. While these helmets may shield your ears, they will expose your face to the wind, allowing the majority of the airflow to pass through. The more wind that enters your helmet, the noisier it becomes.

If you have any of the following, you should consider switching to a full-face helmet, which covers your entire face and helps to block out noise. Most full-face helmets also contain a chin guard, which is useful for both safety and preventing wind from entering the helmet through the chin.

Keep in mind that even full-face helmets have different levels of noise reduction. Choose a helmet that is specifically designed with noise reduction in mind for the quietest riding. Aerodynamic technology and designs that lessen wind turbulence are typically included.

If you’re not sure which helmets are the quietest on the market, I recommend the  Shoei GT-Air 2 silent helmet. The GT-Air 2 inherits the GT Air’s performance, design, and usefulness, and with an aerodynamic design that enhances not just wind noise reduction but also road safety, it succeeds where the previous model failed.

The GT Air is made up of Shoei’s proprietary Advanced Integrated Matrix (AIM), which is made up of layers of fibreglass and organic fibres. This puts it on par with many other helmets on the market in terms of weight.

Get a well-fitted helmet 

One of the biggest reasons your helmet makes a lot of noise while riding is because it doesn’t fit properly on your head. When the wind blows on the sides and bottom of the helmet, generating vibration, it will generate noise if the padding within it has shifted or gotten compressed after a lengthy drive.

Motorcycle helmets should fit snugly on your head, with no gaps between you and the helmet, to reduce turbulence and provide further soundproofing benefits. For safety, it should sit parallel to both cheeks, with even pressure around both edges and about two fingers’ breadth away from the brows. There should be no twists in the material, only smooth curves that fit the face features without holes where air can enter, resulting in less noise entering the ears through open spaces.

A secure helmet will also prevent your head from bobbing around and your neck muscles from tensing up, both of which can cause tiredness.

This way, even if you don’t have any soundproofing, the helmet will absorb some of the noise and you won’t have to worry.

Wear a Wind Blocker

As you may have guessed, the majority of the noise you hear when riding is caused by wind slipping beneath your helmet and resting on your neck.

If your helmet lacks heavy padding in this area, you should invest in padded helmet support, which works by entirely sealing the gap beneath the helmet to reduce turbulence noise.

The PROFOX-PF3115 is a wonderful buy if you don’t already have one. It doesn’t simply keep the wind out and support your neck for comfort; because of its flame-retardant foam lining, it also protects you in the event of a fire. It also has a Velcro closure mechanism that keeps it securely in position when you speed up and comes in three sizes to provide a snug fit for persons of various sizes.

If you don’t like wind blockers, a helmet with a good neck roll can be a good alternative for wind protection. A jacket like the Schuberth C3 Pro would be ideal because it has a double neck roll that not only keeps the wind out but also keeps you warm.

Earplugs

Buying earplugs is one of the most common and convenient ways to deal with wind noise. These are simple and effective techniques to shield your ears from excessive noise.

They fit most ear sizes and are pleasant to wear with your helmet. The silicone absorbs sound well and comes with an aluminium carrying box for storage and transportation. These days, custom-fitted earplugs are quite affordable and pleasant on lengthy journeys. One-size-fits-all choices have come a long way, and their design is remarkably similar to that of musicians’ earplugs. They use the size of the hole in the plug to isolate dangerous frequencies. This means you can still hear what’s going on around you while being shielded from the potentially dangerous elements.

Change the Riding Position

When it comes to managing how much wind hits the lower area of your helmet, your riding position is crucial. If you’re having trouble with a noisy helmet, try changing how you sit on your bike to assist lessen body conducted noise.

Sit on the cushioned section of your bike rather than the metallic part, as some riders do, for a calmer ride. The cushion effectively absorbs the majority of the sound vibrations created by a screaming engine, reducing noise transmission to your ears through the body. 

 

Invest in a Scarf/balaclava

Balaclavas and scarves are a low-cost but effective choice. Sports Bike Shop has this one for less than a tenner.

Noise is reduced by anything that reduces the quantity of wind entering your helmet from the bottom.

In general, your balaclava should feel tight at first before stretching to fit your face.

The goal here is to seal air spaces to improve temperature and noise insulation.

Balaclavas that roll down below your jacket’s collar line will keep you warm and reduce the volume.

Noise can be significantly reduced by wrapping a scarf over your neck and tucking it securely inside your helmet. If you wear it with a balaclava, things will be a lot quieter.

Make Windscreen Adjustments

When riding, the primary function of a motorbike windscreen is to guide wind up and away from your head. However, some helmet, windscreen, and rider height combinations might enhance wind noise.

If your helmet is making noise, make sure the windscreen is high enough to direct all of the airflows up and over your head. Try lifting it if it isn’t doing that in the stock position. You shouldn’t experience any impact from the airflow on your head when riding if it’s set high enough.

A windshield spoiler like the Justech can be useful if you’re particularly tall. Its height will be increased by attaching it to your windscreen, ensuring that all airflow is directed up and over your head for a calmer ride.

Ensure You Have a Well-Fitting Visor

Even when wearing a full-face helmet, the visor’s seal can be a bit noisy.

Most helmets have a ratcheting system that allows you to leave the visor partially open or closed. However, the visor on certain helmets does not seal completely, causing turbulence noise. Others are equipped with low-quality visors that loosen over time, resulting in rattling noises when driving.

When shopping for a helmet, look for one with a high-quality visor that won’t loosen over time or leave any gaps when closed. For a calmer ride, close the visor before hitting the road, even if it should go without saying to any seasoned rider.

Conclusion

Motorcycle helmets are primarily designed to protect your head, but technology has advanced in recent years to stay up with the latest soundproofing advances without losing safety.

Unfortunately, sometimes, but not always, this comes at the cost of a heavier helmet. Not everyone has the financial means to update their present motorbike helmet.

Trying to ignore the wind and noises from the motorcycle as well as other vehicles on the road may be quite distracting, which is why motorcycle riders should take precautions to reduce noise levels for a safer ride. If you can’t afford to upgrade to one of the helmets described below, there are alternative less expensive ways to adapt your existing helmet to assist in minimising wind noise.

Frequently Asked Questions (FAQs): How to soundproof a motorcycle helmet?

Is it true that full-face helmets are quieter than modular helmets?

Wouldn’t you believe it if I told you? Modular helmets, on the other hand, provide superior noise protection than full-face helmets. They’re also the quietest motorbike helmets on the market. A full-face helmet’s head hole must be large enough for you to fit your head through.

Why is my Shoei helmet making such a racket?

Because vibration is the source of noise within our helmets, the most likely culprit is moving components. As a result, inspecting the vents and visor is always worthwhile. A visor that isn’t properly sealed or is loose will make a lot of noise. Low-quality vents will loosen and rattle in the wind with time.

Why does my motorcycle helmet whistle?

When the visor is raised, any helmet will whistle. It has something to do with the airflow across the visor’s top.

Do carbon fibre helmets make a lot of noise?

Surprisingly, both fibreglass and carbon fibre helmets received the same three ratings for noise, with a half-star difference for weight. And, as you progress up the helmet range, so much effort is put into making these helmets quiet that they all sound nearly the same.

Is it possible to use noise-cancelling headphones on a motorcycle?

If you want to use your helmet’s communication system or listen to music, you must first put on Noise Canceling Motorcycle Hearing Protection equipment, such as earplugs, and then lower the volume down. If you simply try to amplify the sound to compensate for the wind, you will only hasten the onset of hearing loss.

On a motorcycle, what is buffeting?

Buffeting is a specific, exceedingly uncomfortable, sort of turbulence. The wind strikes our helmet at such a resonant frequency and with such force that a low droning sound is produced. It can even be so strong that it causes our helmets to shake or vibrate, distorting our eyesight.
