How Loud Is Too Loud? Kids' Headphones on Planes (and Everywhere Else)
You're 40 minutes into the flight. The engines are humming, the snack supply is holding, and your toddler is finally settled with their favourite show. Then you notice the little hand creeping up to the volume button. Again.
It's one of those parenting moments where you're not quite sure what the right answer is. How loud is too loud? What volume limit should kids' headphones have? And why does it seem so much worse on a plane?
Here's what's worth knowing.
Why little ears need more care
Children's ear canals are smaller than ours, which means the same volume can be more intense by the time it reaches their eardrum. And young kids can't tell you when something's too loud. They just turn it up until they can hear it properly.
Hearing damage from loud sound builds up over time and is permanent. The good news is that it's also preventable. What matters is a combination of two things: how loud, and for how long.
What volume limit should kids' headphones have?
Sound is measured in decibels (dB), and the scale is logarithmic. A small increase in the number is a big increase in sound energy. As a rule of thumb, every 3 dB increase halves the amount of time it's safe to listen.
In 2019, the World Health Organization and the International Telecommunication Union released a global standard for safe listening on personal audio devices. For children, it recommends listening levels of 75 dB, based on up to 40 hours a week. For adults, it's 80 dB.
To put that in context:
| Sound | Roughly |
|
Normal conversation |
60 dB |
|
Plane cabin at cruising altitude |
75-85 dB |
|
Common cap on kids' headphones |
85 dB |
|
Standard earbuds at full volume |
90-110 dB |
You'll notice that a lot of kids' headphones are capped at 85 dB, which is higher than the WHO guideline for children. That doesn't make them unsafe, because a cap is a ceiling, not a target. But it does mean the cap alone isn't the whole answer. The volume you actually set, and how long they listen, matter just as much.
What "volume-capped" actually means
A volume cap, or limiter, stops headphones from going above a set maximum, however high the volume on the device is turned up.
How it's built makes a difference. In Bluetooth headphones, the limit is usually built into the electronics, so it works no matter what you connect to. In some wired headphones, the limit sits in the cable, and plugging in a different cable or adaptor can bypass it. Research on children's headphones has also found that limiters don't always perform as advertised, depending on the device they're paired with.
Either way, treat the cap as a safety net, not the setting to aim for. Headphones capped at 85 dB can still be listened to comfortably at much lower volumes, and for long flights, that's where you want them.
Why I wanted a cap I could trust
I learned this the practical way. After a long day at the zoo in Sydney, my daughter was overtired, overwhelmed, and desperate for comfort and a nap. I put her headband on, played her music from my phone, and carried her around until she drifted off.
To keep my hands free, my phone went into my pocket. And the whole time, I kept pulling it out to check the volume, worried I'd bumped the buttons without noticing.
That's the real value of a cap. You can't watch the volume every second, especially when you're carrying a sleepy child through a crowd or juggling bags down an aircraft aisle. A limiter means an accidental bump can only go so far. It's not a reason to stop checking, but it is one less thing to worry about.
The arm's-length test
You don't need a sound meter to check. Two quick tests work anywhere:
- The arm's-length test. If you can hear your child's show from an arm's length away, it's too loud.
- The conversation test. If your child can't hear you speaking at a normal volume while they're wearing them, it's too loud.
A simple habit is to keep the device at about half volume. Most phones and tablets also let you set a maximum headphone volume in their sound settings (on iPhone and iPad, look for Headphone Safety). It takes a minute to set up before you leave home, and it means you're not negotiating volume at 35,000 feet.
Why planes are the hardest place to keep volume down
A plane cabin at cruising altitude typically sits somewhere between 75 and 85 dB. That constant engine and air noise is exactly why kids keep turning the volume up: they're trying to hear over it. Take-off and landing are louder again.
Planes are also where listening time stretches out. A two-hour show binge at home is unusual. On a long-haul flight, it can be six hours or more.
A few things help:
- Set the device limit before you board, not once they're already used to it loud.
- Take listening breaks. Swap to books, stickers or snacks every hour or so.
- Choose your seat if you can. Noise varies around the cabin, and seats near the engines and at the rear tend to be louder.

Headphones vs headband: which is right for your child?
The best headphones for a child are the ones they'll actually keep on at a sensible volume. Here's how the main types compare:
- Over-ear headphones can block out more cabin noise when they fit well, which helps kids keep the volume down. But they can feel heavy and tight on small heads, and they're hard to sleep in.
- Earbuds are small and easy to pack, but they tend to fall out of little ears, and many standard earbuds aren't volume-capped at all.
- Headband headphones are soft fabric bands with flat speakers inside. There are no hard parts to press on ears, they stay put when kids move around, and they're comfortable enough to sleep in. They block less outside noise than a snug over-ear pair, so the volume habits above matter just as much.
Your quick checklist
- Choose volume-capped headphones, and check what the cap is.
- Set a maximum headphone volume on the device before you travel.
- Aim for about half volume, and use the arm's-length test.
- Build in listening breaks on long flights.
- Watch for signs of trouble afterwards: ringing in the ears, muffled hearing, or asking you to repeat things more than usual. If you notice any of these, check in with your GP.
Frequently asked questions
What decibel level is safe for kids' headphones?
The World Health Organization recommends that children's listening is kept to around 75 dB, based on up to 40 hours a week. Louder listening is OK for shorter periods, but every 3 dB increase halves the time it's safe to listen.
Is an 85 dB volume limit OK for toddlers?
85 dB is the most common cap on kids' headphones. It's a maximum, not a recommended level. Keep the device at around half volume and limit listening time, especially on long flights.
Can toddlers wear headphones on a plane?
Yes. Volume-capped headphones help them hear their show over cabin noise without the device being turned right up. Choose a comfortable style they'll keep on, set a volume limit on the device before you board, and build in breaks.
How long should kids use headphones?
There's no single number: the louder the volume, the shorter the time. As a rule of thumb, keep the volume around half and take a break every hour or so.

We designed the AirCozi® Travel Headband for exactly this: long flights, little ears, and parents who'd rather not spend the trip policing the volume button.
It's a soft, stretchy headband with flat speakers built in. It connects by Bluetooth, the volume is capped at 85 dB, and it's comfortable enough to fall asleep in (which, on a long-haul flight, is the whole point).
