Still remember the mosquito ringtone thingy? Quite some time ago, there is a report that students are using mosquito ringtones in school, and when it rings, only the youngsters can hear it, but not the old one. Yesterday, I stumbled upon a website that have a collection of the mosquito ringtones from 8kHz to 22.4kHz.
It’s said that most people can hear the pitch tones from 8kHz to 14.1kHz – but only teenagers are able to hear mosquito ringtones above 17kHz. I have tested it myself, the highest I can go is only 18.8kHz. Hear almost nothing for pitch tones higher than 18.8kHz. What about you?

wow, i can’t hear anything at all at 22.4kHz!
Wow! Really a good test! Example in life we using this? Anybodys know? Is’t like dolphin or ghost using high freuquency?
yeah ghost have a high frequence sound too, really really high, I don't know exactly how high is it…
I get my speaker louder this time, and I can hear up to 19.9kHz. Weird, louder means easier to hear?
Oh yeah, sorry for voting the lowest one. O.O (Please disregard it.) I can hear up to 19.9kHz at the minimum possible volume.
Only managed to hear at 21.1kHz.I maximized the sound at 22.4kHz still can’t spot any sound(Are you sure you there’s any sound recorded in 22.4kHz?).I still remember Science book form 2 has told us that our range of hearing sounds are between 20Hz to 20000Hz/20kHz.
I’m nearly 31 and I can clearly hear the 21.1kHz tone but the 22.4 is silent for me.
I’ve always been able to hear annoying sounds that my friends and peers can’t, (even lower frequencies). Sometimes I get strange looks from them when I ask them seriously, “You can’t hear that?”
Also, just as a follow up, I downloaded these tones and opened the 22.4kHz mp3 in Audacity (a sound editor). Visually I could see nothing (the sound graph was just a line). I attempted to both amplify and change the pitch of the mp3.
There’s actually no sound data at all in that file, so Bobby, you’re right. There isn’t actually any sound there at all. Whether this was done by design or accident I don’t know.
There’s no sound at 22.4 because i tested this with my dog. Dogs can hear frequencies much higher then humans. I tested every frequency and she seemed to be startled, turned around and barked except for 22.4 mhz.
I can faintly hear 21.1 kHz and I am soon to be 32. To catch my attention as a ringtone I would have to use 19.9 kHz or lower. I haven’t looked at the wave form for any of the files but I think you’re right about the 22.4 kHz being bogus. My cat only responds to the 21.1 kHz file and lower.
Also I think the idea of age changing your hearing is kind of crazy. It’s not the years of living it’s what you do to yourself in those years. I keep the radio lower than most and I often cover my ears at concerts.
OMG I'm getting Older
i'm going to be really really old,… I can hear up to 17.7khz but is not clear 
i went to the original site, and it said there was no sound on the 22.4Hz file
i wanna put this link on facebook how?
check this website out n c which frequencies u can hear bring ur parents to da computer to c if they can hear the ones u hear
