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.

      How loud it is in the headphones depends on the output of the amplifier, which depends on how loud the volume is turned up as well as the efficiency of the phones, and a lot of other things as well.

      I find a lot of the music I have on my phone is barely audible at the volume limit that requires me to press a button to OK it in case I go deaf. My headphones have good sound quality but presumably are not very sensitive, but the volume of the original recordings clearly varies by over 20dB.

      There is clearly no international standard for how many millivolts produces how many dB, and never will be, because it is a stupid idea. However, not as stupid as the report that led to this article. If you need a plan for how to cope with the stupid children of stupid parents this is NOT it! I am pretty sure that very few headphones are as loud as the London Underground trains, but children regularly travel by train.

    This is like regular news. Like, water is good but if you drink too much you can die!

  19. The m in dBm is milliwatts by raymorris · · Score: 1

    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)".

  21. LilGadgets on Volume Control Methodology by Anonymous Coward · · Score: 0

    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.
