At 65 mph, the wind hitting your motorcycle helmet generates around 110 to 116 dB of noise. That’s louder than a chainsaw. At those levels, hearing damage begins in under a minute. Most riders have no idea. If you’ve ever finished a long ride with ringing ears, or felt wrung out in a way that sleep doesn’t quite fix, wind noise is almost certainly behind it. This guide explains what’s happening to your hearing on the road, what the evidence actually shows about earplugs, and what you should look for when picking a pair.

We cross-referenced leading UK motorcycling publications including Bennetts BikeSocial, Motorcycle News, and Bikenrider.com with Tinnitus UK noise data and peer-reviewed research, so what follows is based on evidence rather than received wisdom.

Step 1: Understand what wind noise is actually doing to your ears

Wind noise isn’t just annoying. It sits above 85 dB at motorway speeds, and anything above 85 dB causes permanent, cumulative hearing damage with sustained exposure. At 94 dB (roughly 50 mph on a typical naked bike), you’ve got around 60 minutes before you cross the safe exposure threshold. At 110 dB (65 mph), that window is under a minute.

Research by ISVR Consulting at the University of Southampton found that wind noise inside a full-face helmet peaks between 1 kHz and 4 kHz. Those are the frequencies most critical for speech intelligibility, and the range where cochlear hair cells are most vulnerable to damage. Once those cells are gone, they don’t regenerate. For a lot of riders, tinnitus follows years later.

Hearing damage from wind noise builds slowly. You won’t notice much in a single season. But after a decade of regular riding without protection, many riders show a notch-shaped hearing loss at 4 kHz on audiogram tests. It’s the kind of thing you discover at a hearing check, not the morning after a long run on the motorway.

Step 2: Understand why your helmet is not solving this problem

Most riders assume their full-face helmet is doing the work. It isn’t, at least not enough. Studies consistently find that helmets reduce noise by around 7 to 10 dB at best. That shifts a 110 dB environment to roughly 100 to 103 dB, which is still well above the safe exposure threshold. At 100 dB, hearing damage starts after about three to four minutes.

Aerodynamic shell designs and neck tubes help somewhat, but they can’t overcome the physics. Wind noise is generated at the ear by turbulence from the helmet’s own shape, and no lid has fully solved that. Quieter helmets reduce the problem. None of them eliminate it.

Earplugs are the only reliable fix. Not instead of a good helmet, but on top of one. Riders who use earplugs don’t report feeling cut off from their surroundings. Most say the opposite: removing the constant wind roar lets them hear traffic, sirens, and intercom audio more clearly, because the masking effect is gone.

Step 3: Know the difference between foam plugs and flat-filter plugs

Disposable foam plugs cut all frequencies at roughly the same rate. Wind noise drops, but so do sirens, horns, and your intercom. For a one-off situation that’s fine. On a motorcycle, where situational awareness matters, it’s the wrong trade-off.

Flat-filter earplugs use an acoustic filter to reduce low and mid frequencies (where wind noise lives) more than high frequencies (where speech and warning sounds sit). The overall volume comes down, but the things you need to hear stay clear. You don’t get the muffled, sealed-off sensation that puts riders off foam plugs.

For the odd short ride, foam is fine. If you’re commuting regularly or touring, flat-filter plugs are worth the extra cost, both for your hearing and your wallet over time.

Step 4: Look for independent certification, not just a dB number on the box

Any manufacturer can print a decibel number on the box. The one that matters is the SNR (Single Number Rating), and what matters more than the number is who measured it. In the UK and EU, earplugs need to be tested by an accredited Notified Body to carry the CE mark. Not every brand does this. Self-reported ratings are common, and they’re worth treating with scepticism.

When you’re comparing options, look for the name of the testing lab on the packaging. PZT GmbH in Wilhelmshaven (NANDO Notified Body No. 1974) is one of the most thorough in Europe, testing to EN 352-2 standards. A certification from them means the attenuation rating was measured on real subjects across a statistically valid panel, not calculated from a model.

For motorcycling, aim for an SNR between 22 and 24 dB. That’s enough to bring a 110 dB environment down to a manageable level for several hours of riding. Go much above 25 dB and you start compromising situational awareness.

Step 5: Get the fit right before you ride

A poorly fitting earplug delivers a fraction of its rated attenuation. This is probably the most common reason riders try earplugs once, decide they don’t work, and go back to foam. Getting the fit right matters as much as choosing the right product.

Silicone flanged earplugs aren’t inserted like foam. You don’t roll or compress them. Push the smallest flange in first, then ease it forward until you feel the seal form and the wind drops noticeably. Snug, not painful. If you have a narrow or unusually shaped ear canal, BOLLSEN’s AR KI TECH service lets you upload two photos of your ears and get a size recommendation based on AI measurement, cutting down the trial and error considerably.

Once you’ve got them in, put your helmet on. The plug should sit completely flush. If you feel pressure from the padding, it’s either not deep enough or you need a smaller size. Sort this before you ride, not halfway up the A1.

Step 6: Build earplugs into your pre-ride routine

Inconsistency with earplugs usually comes down to friction. You’re already juggling gloves, helmet, jacket, and keys. Nobody wants to add another step that involves fiddling with small objects in cold hands.

Two habits make a real difference. Keep your earplugs inside your helmet. The Moto+ comes with a small metal travel case with a keyring clip, so it’s easy to leave it sitting inside the lid. Then put earplugs in before the helmet goes on, not after. Trying to thread flanged plugs through padding makes a good seal much harder to achieve.

After a handful of rides, it stops feeling like an extra step. Riders who’ve built the habit tend to say rides feel shorter and they arrive less wrung out. Some of that end-of-day exhaustion after a long motorway run is acoustic fatigue, and cutting that down makes a genuine difference to how you feel.

Frequently Asked Questions

Are earplugs legal to wear while riding a motorcycle in the UK?

Yes, completely. There’s no UK law that prohibits wearing earplugs on a motorcycle. Some European countries have restrictions, but UK roads law doesn’t. Advanced riding instructors regularly recommend them, and organisations including Bennetts and the Institute of Advanced Motorists treat them as normal kit for long-distance riding.

Will earplugs affect my ability to hear sirens and other traffic?

With flat-filter earplugs like the Moto+, no. These are designed to preserve higher-frequency sounds while bringing down the low-frequency rumble of wind and engine noise. Sirens and horns sit in the higher range and stay clearly audible. Foam plugs are different: they muffle across all frequencies, which is why most experienced riders use flat-filter options. A lot of riders actually find they hear traffic more clearly with plugs in, because the constant wind roar stops masking everything else.

How loud is wind noise under a motorcycle helmet?

At 40 mph, it’s around 90 dB inside a typical full-face lid. At 65 mph, it reaches 110 to 116 dB depending on the helmet design and your riding position. Research by ISVR Consulting at the University of Southampton puts noise above 85 dB from around 30 mph on most bikes. A helmet knocks that back by 7 to 10 dB, which still leaves you above safe exposure levels at motorway speeds.

What’s the difference between foam earplugs and flat-filter earplugs for motorcycling?

Foam plugs block all frequencies fairly evenly, so wind noise drops but so do sirens, horns, and intercom audio. Flat-filter plugs use an acoustic filter to target the low and mid frequencies where wind noise sits, while leaving higher-frequency sounds (speech, warning sounds) more intact. For riding, that’s a meaningful difference. Flat-filter plugs cost more upfront, but they’re reusable, so the cost per ride drops significantly over time.

How long can you ride before wind noise starts damaging your hearing?

At 85 dB (roughly 30 mph on a naked bike), the safe daily limit is 8 hours. At 94 dB (50 mph), you’re down to around 60 minutes. At 110 dB (65 mph), damage can begin in under a minute. Most motorway commutes run well above 50 mph for sustained periods, which means regular riders are crossing safe exposure thresholds on nearly every journey without protection.

What dB of earplug do I need for motorcycling?

Aim for an SNR of 22 to 24 dB. That’s enough to bring a 110 dB environment down to roughly 86 to 90 dB, which keeps you within safe limits for several hours of riding. Going above 25 dB starts to affect your ability to hear sirens and traffic clearly. And when comparing products, make sure the SNR rating comes from independent testing, not a manufacturer’s own assessment.
