Aircraft noise and your hearing: ear protection for spotters, airshows and runway ends

The A330 rolls onto the runway, the engines spool up to takeoff power, and a second later you feel the sound in your chest. For many spotters, that is exactly why they drive to the runway end. But your hearing remembers every one of those moments. Hearing protection for plane spotting looks excessive at first glance, but at airshows and loud spots it is simply sensible. This guide explains what noise does in the ear, which values make good guidance and which protection suits which spot.

Hearing protection for spotting: the short answer

You need hearing protection whenever high level and long duration come together or when you stand very close to a sound source. That mainly concerns three situations: runway ends and departure paths with many takeoffs, airshows with fighters, and military airfields. On an observation deck with some distance from the runway, you are generally fine without protection as long as you are not standing right at the loudest spot for hours.

The principle behind it matters: for your hearing, the noise dose counts. A single takeoff is loud, but short. Five hours at the fence with a takeoff every two minutes is a different calculation. And a display with afterburner plays in a league of its own again.

What noise does in the ear

In the inner ear, the cochlea contains fine hair cells that convert sound waves into nerve signals. Very loud or prolonged sound overloads them. At first the ear reacts with a temporary threshold shift: after a spotting day everything sounds a little duller, maybe there is a faint ringing. This usually recovers within hours to a few days.

If it happens often enough, something remains. In humans, dead hair cells do not grow back, so noise-induced hearing loss is permanent. Typically the high frequencies suffer first – a hearing test often shows a dip around 4,000 hertz. In everyday life you notice it because you understand conversations in loud surroundings less well. A lasting tinnitus can be added, that is, a whistling or hissing without an outside source.

A special case is acoustic trauma: an extremely loud, very short sound impulse, such as a gunshot or a firecracker right at the ear. In normal spotting it is rare, but at airshows with pyrotechnics or demonstrations with bang effects it cannot be ruled out.

Understanding decibels without a physics degree

Decibels are a logarithmic scale. Three rules of thumb follow that you can apply right at the fence:

• Plus 3 dB = double the energy. For your hearing, that means: with 3 dB more, the time you can expose yourself to the noise without risk is halved. EU occupational safety and the US agency NIOSH calculate with exactly this exchange rate.
• Plus 10 dB ≈ perceived as twice as loud. So your ear underestimates how strongly the load increases.
• Double the distance ≈ minus 6 dB. For a point source outdoors, the level drops by roughly this value with every doubling of distance. Ten steps back from the fence is therefore often more effective than you think.

The WHO sums this up for leisure noise in a simple scale: your hearing tolerates about 80 dB for roughly 40 hours per week, at 90 dB it is only about four hours, at 100 dB about 20 minutes. That is not a limit for a single takeoff but a weekly balance – and anyone who was at the runway on the weekend and at a concert in the evening has both items on the same account.

Occupational safety as a guide

For employees in Germany, the Noise and Vibration Occupational Safety Ordinance regulates when hearing protection is needed. It does not apply to you as a spotter, but it provides good reference points:

Value	Daily average over 8 hours	Peak level	What follows at the workplace
Lower action value	80 dB(A)	135 dB(C)	Employer must provide hearing protection
Upper action value	85 dB(A)	137 dB(C)	Hearing protection must be worn
Value at the ear under hearing protection	at most 85 dB(A)	at most 137 dB(C)	Protection must be chosen so that it is not exceeded

That is why apron staff and marshallers at the airport almost always work with earmuffs – a good hint at how loud it gets near engines. How airports measure aircraft noise in their surroundings is described in the article Measuring aircraft noise.

Where it really gets loud when spotting

Not every spot is the same. The load depends on how close you stand, which phase of flight you see and how long you stay.

Situation	Load	Recommendation
Observation deck, hill with distance from the runway	usually moderate, short peaks	have plugs with you as a backup
Under the landing approach	overflight short, engines at idle range	protect with many landings and long sessions
Runway end behind departing jets	high levels, engines at takeoff power	plan for hearing protection, keep your distance
Engine tests, taxi traffic right at the fence	long-lasting noise	wear protection as long as the engines are running
Airshow with fighters and afterburner	very loud, for hours	hearing protection for the whole day, especially for children
Military airfield during training operations	fighters taking off, often with afterburner	same as at the airshow

Runway end and departure

A departing jet is loudest behind and to the side of the takeoff position, because the engines work at full power there and the sound is radiated backward. At famous spots such as the runway end in Skiathos or Maho Beach on Sint Maarten, the exhaust blast adds to the noise. How dangerous that can get is described in the guide Jet blast – your hearing is only one of several concerns there.

Under the approach path

Landing aircraft fly with much reduced engine power, and the overflight lasts only a few seconds. At platforms such as Zeppelinheim at Frankfurt Airport, a single widebody jet is still impressively loud. With dense traffic and a whole afternoon it adds up. What else to keep in mind under the approach path is in Spotting under the approach path.

Airshows and fighters

Fighters such as the Eurofighter Typhoon or the F-35 are among the loudest sound sources you meet as a spectator – even more so with the afterburner on. At events such as the Royal International Air Tattoo or ILA Berlin, you also stand at the show line for many hours. That is the classic case of too little protection: in the morning everything still feels harmless, in the evening your ears ring. Which shows are worth it in Europe is shown in the overview Airshows in Europe. It gets similarly loud at military airfields during training operations – which rules apply there for photography is explained in Photographing at military airfields, and which patterns you see there is shown in Recognizing fighter jets in Europe.

Which hearing protection suits you?

Hearing protection comes in four basic forms. Testing is done under the European EN 352 series of standards; on the packaging you find an attenuation value (SNR) or the more detailed HML values for high, medium and low frequencies.

• Foam plugs: inexpensive, light, strongly attenuating. They only work if they sit deep enough. To insert one, you roll the plug thin, pull your ear up and back, push it in and hold it briefly until it has expanded.
• Preformed plugs with flanges or a filter: reusable, often with more even attenuation across frequencies. Music and speech sound more natural with them.
• Earmuffs: on and off in seconds, ideal for changing noise phases and for children. Drawback: warm in summer, and they seal less well with glasses or a hat.
• Custom earplugs: fitted by a hearing aid acoustician, they sit the same every time you insert them and are comfortable even over many hours. The investment pays off for frequent spotters and airshow fans.

Active earmuffs with microphones exist as well: they let quiet sounds and speech through and turn loud levels down. For spotters who want to catch announcements and conversations, that is a comfortable option.

Practice beats lab value

The attenuation value on the package comes from the lab. In everyday use, plugs rarely sit perfectly. In occupational safety practice, deductions are therefore applied – roughly 9 dB for plugs, 5 dB for earmuffs and 3 dB for custom earplugs. Too much attenuation is not ideal either, by the way: if you can’t hear anything at all, you no longer notice announcements, vehicles on the way to the spot or instructions from marshals.

Kids at the runway and show line

When spotting, children are often the first to be thrilled by a low-flying jet – and the last to cover their ears at noise before it is too late. For them, child-size earmuffs, tested to EN 352-1 and with a manufacturer’s age rating that fits the child, are the best choice. Plugs are unsuitable for small children: they fit poorly in small ear canals and can be swallowed.

Put the earmuffs on before the first takeoff, not only when the child gets frightened. At airshows that applies all day. You will find more tips for the family outing in the guide Plane spotting with kids.

Hearing protection and video: can they go together?

Many spotters film and want to experience the engine sound deliberately. The two don’t rule each other out. The camera’s microphone records the sound whether or not you wear plugs. What you monitor through headphones should be set quiet – if you turn headphones up to drown out the aircraft noise, you only add to the load. How to record clean sound without wind and overload ruining everything is explained in Recording engine sound.

What to keep in mind

• Distance is free. Every meter away from the loudest spot lowers the load. At many spots, a row farther back has hardly worse visibility.
• Plan breaks. The WHO recommends recovery phases for the ears in loud environments. Between two waves of takeoffs, in the car or in the café behind the spot, your hearing regenerates.
• Insert early. Hearing protection only works if it is in place before it gets loud – not when the jet has already passed.
• Bring spares. Foam plugs like to fall in the sand or grass. A few spare pairs in the camera bag cost almost nothing; the gear checklist and the airshow day checklist help with packing.
• Stay at the fence, not behind it. If you ignore barriers for better pictures, you risk not only trouble but also stand where it is loudest and most dangerous. The rules are summarized in Proper behavior at the airport fence.

Conclusion

Aircraft noise is part of spotting, and nobody has to plug their ears on the observation deck. It becomes a problem where high levels and many hours come together: at the runway end, with fighters and at airshows. There, hearing protection is not a spoilsport but the precondition for still enjoying the sound the same way in ten years. Foam plugs in your jacket pocket, earmuffs for the kids, a few meters of distance and breaks in between are completely enough in most cases.
