I know this comment may not reach many people, but doing an online test with whatever speakers or headphones you have shouldn't be counted as definitive proof of aging hearing or hearing loss. The frequency response and impedence of modern consumer headphones rarely focuses high end detail, and unless you're listening on a pair of £1200 Sennheiser HD800s with an accurate, flat and impressive reproduction of high Hz range audio, don't lose sleep over it. It could even just be wax buildup muting the high end, too. This goes out to Tom as well. I thought I was losing mine, went for a professional cleaning in London and had a test done. Perfect range beyond 20kHz and in the sub ranges.<br><br>But to anyone else, go buy some god damn. Earplugs, that is.
