Danmarks Motor Union Names Earmuffz Official Hearing Partner for Motorcycle Sport

New York, US, October 7th, 2026, FinanceWire

Federal measurements put race-day noise at 96 dBA in the stands and 114 dBA for drivers, with peaks above 130 dB in the pit. In Denmark, the national motorcycle-sport federation has made hearing protection a safety item. In the United States, it is still mostly left to the individual.

Danmarks Motor Union (DMU), Denmark’s national federation for motorcycle sport and a member of the Fédération Internationale de Motocyclisme (FIM), has named Earmuffz its official hearing partner, putting hearing protection in front of riders, mechanics, officials and spectators as part of how the sport is run safely.

The partnership, announced on 28 August 2026, comes as federal measurements show race-day noise reaching 96 dBA in the stands, 114 dBA for drivers, and peaks above 130 dB in the pit. In Denmark, the national motorcycle-sport federation has made hearing protection a safety item. In the United States, it is still mostly left to the individual.

The Numbers Behind the Noise

The National Institute for Occupational Safety and Health (NIOSH) measured noise at three US stock car circuits and published the results in 2010. They are not marginal numbers.

• Drivers recorded a time-weighted average of 114 dBA during practice at Bristol — a noise dose NIOSH described as 50 to 900 times higher than the allowable occupational daily dose. At that level, the recommended daily exposure limit is exceeded in less than a minute.
• Spectators recorded a time-weighted average of 96 dBA during the race, taking on two to ten times the dose of someone working a full 40-hour week at the maximum allowable limit. The daily limit is passed in under an hour.
• Peak sound pressure in the pit area reached and exceeded 130 dB at all three tracks.
• Race team members absorb 12 to 21 hours of intensive noise exposure every week, for up to 40 consecutive weeks a year.

The reason these numbers escalate so quickly is the exchange rate. NIOSH sets its recommended exposure limit at 85 dBA over eight hours, and recommends halving the exposure time for every 3 dB above it.

Applying that rule gives eight hours at 85 dBA, about 15 minutes at 100 dBA and under a minute at 114 dBA. Knowing how loud is too loud matters because loudness does not add up. It multiplies.

The Riders Pay for it First

Under a helmet, the engine is not even the main problem. Low-frequency wind noise alone reaches 90 dB(A) at 40 mph and rises with speed to 110 dB(A) at 100 mph, with levels on the order of 120 dB(A) at 150 mph (McCombe, Binnington and Nash, British Journal of Sports Medicine, 1994).

In the same study, of 44 Grand Prix motorcyclists examined, 20 — 45 percent — had hearing losses greater than expected for age-matched controls.

It is Not Only the Professionals

The assumption that hearing damage is an occupational problem does not survive the national data. In the 2011–2012 National Health and Nutrition Examination Survey, analyzed by the Centers for Disease Control and Prevention, nearly one in four US adults aged 20 to 69 showed signs of noise-induced hearing loss. Among adults who reported no on-the-job noise exposure at all, one in five still had a noise notch in one or both ears.

That damage is coming from somewhere other than work. And among workers who are exposed to hazardous noise, 53 percent report not wearing ear protection at all (Green et al., 2021).

The stands are not a safe distance. They are simply a quieter part of a loud place.

One Federation Decided to Treat it as a Safety Matter

DMU was founded in 1914 and governs motocross, speedway, road racing, trial and enduro through clubs across Denmark. In the federation’s 2023 member survey, the majority of respondents confirmed that safety is a focus in the sport and that a great deal is being done in the area. The Earmuffz partnership, announced on 28 August 2026, extends that focus to a risk that is invisible and painless while it is happening.

“We at DMU are very pleased with our partnership with Earmuffz. It gives us the opportunity to offer our members a strong, high-quality product that can help protect their hearing and thereby contribute positively to their health, both now and in the long term. We see Earmuffz as a strong partner with quality products that are very well suited to the needs of motorsport.” — Mark Blondin, Communications Manager, Danmarks Motor Union

Denmark’s own numbers explain the urgency. 777,000 Danes — 16.1 percent of adults — reported tinnitus in 2021, a 27 percent increase since 2017, with the steepest rise among 16-to-24-year-olds (Den Nationale Sundhedsprofil, via Høreforeningen). Globally, the World Health Organization estimates 430 million people live with disabling hearing loss, and that more than a billion young adults are at risk of permanent, avoidable hearing loss from unsafe listening.

Protection Without Losing Communication

Hearing protection at a race is not about silence. A rider needs to hear a marshal’s flag and a helmet communication system. A mechanic needs to hear the car and the crew chief. A parent in the stands needs to hear their child. Protection that removes everything gets taken out, and protection that is taken out protects nothing.

Earmuffz makes reusable earplugs that lower harmful sound while keeping speech and warning sounds audible. Every product in the range holds its own laboratory certification: all products were tested in accredited laboratories in 2026 to EN 352-2, the European standard for earplugs that underpins CE marking, and to ANSI S3.19, the US test method behind the EPA Noise Reduction Rating. Earmuffz holds laboratory certificates per product rather than relying on a self-issued declaration of conformity.

For riders, Earmuffz Adventure reduces noise by 19 dB (SNR) while preserving traffic, horns and communication systems. For the paddock, the pit and the stands, the Earmuffz Complete Series offers four certified levels — 15, 20, 21 and 24 dB (SNR) — in a single pair, changed by a removable insert as the day gets louder or quieter. SNR is the European single-number rating; the same products are tested to the US ANSI method.

“Motorsports is one of the loudest environments most Americans will ever spend a weekend in, and the damage it does is silent, cumulative and permanent. The federal measurements have been public since 2010. What was missing was anyone in the sport treating hearing as a safety item rather than a personal preference. DMU has done that, and we think it is a model worth copying. Every Earmuffz product is tested and certified individually, so whether you are on the bike, in the pit or in the stands, you know exactly what protection you are getting.” — Frederick, Spokesperson, Earmuffz
