Some Children's Headphones Raise Concerns of Hearing Loss, Report Says (go.com)
Some headphones marketed for children may not restrict enough noise for young ears. From a report on ABC: The Wirecutter, a technology products review website (owned by the New York Times), tried out 30 different children's headphones for style, fit and safety by using both a plastic model ear and a few real children. "There's no governing board that oversees this," Lauren Dragan, the Headphone Editor at The Wirecutter, told "Good Morning America" in an interview that aired today. Dragan added that the headphones for children all claim to limit volume to around 85 decibels. Sound below the 85 decibel mark for a maximum of eight hours is considered safe, according to the World Health Organization. The Wirecutter report found that some of these headphones emit sound higher than the 85 decibel mark. The full report here.
doesn't work as advertised... news at 11.
How loud other people raise the volume on headphones, cars, movie theaters and live concerts. I don't go anywhere without my earplugs designed to attenuate 20 decibels. My forced classical music training during my school years, yes I was in a marching band and went to band camps, gave me great appreciation to enjoyment of music which I intend to do by protecting my hearing.
When I was a kid back in late 80's early 90's, I was constantly listening to Megadeth on my Walkman with the volume cranked up all the way. I paid the price for that. Now in my adult life people get frustrated when I can't hear them. I can easily trace the decline in my hearing back to my Walkman days. As near as I can tell, no one at the time thought it was serious matter at all.
I still listen to Megadeth though.

I can't hear you.
-linux... they can't *give* that shit away.
Back in the 1980s everybody had either a Sony Walkman portable tape player or some brand trying to be like the Walkman. With these portable players came lightweight headphones that most kids had playing very loudly.
This is nothing new. It's very old news. Nothing to see here. Move along, move along.
Buy some noise cancelling earphones. You can tell people over and over again about hearing loss but it won't matter if they can't hear that music over background noise of the noisy bus they are on.
Noise cancelling / closed cup earphones will just make you naturally turn down the volume.
What?

If it's too loud, you're too old.
and want their news back.

> I think there were only a handful of my late-teen/early-twenty years where I was in danger of playing my music beyond the pain threshold. Most people (even most kids) are smart enough for the "If it hurts, stop it," rule.
Hearing damage occurs from prolonged exposure to sounds over 85db. Pain starts at about 120db. So your hearing is damaged long before it's painful.
Decibels are a logarithmic scale, 120db (pain) is over 3,000 times as much power as 85db (damage). It takes 3,000X times as many watts to cause pain as it does to cause long term damage.
Every set of headphones should have a label... "Warning, if you are STUPID enough, to turn the volume to 11, do not come crying to us saying our headphones made you deaf. We do not reward STUPIDITY". Screw political correctness!
somebody needs to create a set of headphones (in both normal and "sport" versions) that
1 blocks outside noise (or filters it below danger levels))
2 includes a way for a Guardian/Other Caretaker to send sounds into the headset (even if its a Attn! Chirp)
3 compresses the dynamic range to cut the need to crank the volume
4 clips the top end of volume
Got family members with hearing problems. Probably made worse by loud music concerts, but it is mostly genetic we believe. Anyhow, it isn't a joke to have to wear hearing-aids at the age of 40. You do not want the trouble, nor do you want it for your kids.
Best thing to do is avoid headphones and 100% avoid earbuds for kids. If they have to have headphones (like at our schools), then the only real option you have is to buy child-safe ones that reduce the volume.
It regulates maximum sensitivity of a passive headphone - and maximum SPL for a wireless headphone (or any headphone in wireless mode). It's only required in France right now - recommended in the rest of the EU, and ignored in the rest of the world. It also sets the max SPL at 100 dB.
Browsing at +1 - no ACs, I ignore their posts. So refreshing!
Is the "logarithmic scale" part confusing?
An increase of 10db means it's ten times as much power. That's just the definition of decibel (deci meaning ten).
decibels - power
1 1
10 10
20 100
30 1000
40 10000
Starting with the sound level that causes hearing damage, 85db, ten times as much power would be 95db. If you add ten more d, that's 105db. That means you multiply the power by 10 again (for a total of 100X as much power). 115db is 1000 times as much power.
This is like regular news. Like, water is good but if you drink too much you can die!
More on this after the break.
Yes, yes I did.
The "m" in dBm is milliwatts. So "dBm - power (in Watts)" is means "dB milliwatts in watts". Much like saying "MPH - speed (in feet per hour)".
this post is part of a FUD campaign?
From LilGadgets: We've had quite a few questions about this article so here's a quick answer. We can't recreate the exact conditions of the test ran by Wirecutter so unfortunately we can't answer to the accuracy of their results and claims. What we can say is that we do industry-standard testing during production on each and every headphone with an electroacoustic test meter (the volume limiting we set is on both the internal circuitry as well as the audio drivers). We then take a large sample size post-production to once more test and ensure that the output is within the db range we specify and advertise. You can read more here: https://www.lilgadgets.com/blogs/faq/volume-testing-methodology.
We are in contact with Wirecutter to further understand their testing and investigate how the results of their 1 test on 1 headphone could vary so greatly with the dozens of tests we run on 1000s of headphones. Perhaps we can merge some of their methodology with the audio manufacturing industry norms and create an even better method. With two young children ourselves, child safety is always our priority.
One point we can absolutely agree on and is something that we have stressed since inception of our company is that parental monitoring is necessary at any volume, lower volume is always better, and shorter listening times are safer at any volume.
