The first time I found this was four-years-ago... I heard it then and I can still here it now. I'm 28 and other then my 6-year-old niece and 11-year-old nephew, I'm the only person in my family that can hear this...
A pioneering study testing five different ultrasonic devices against four mosquito species convincingly demonstrated that ultrasound in the 20-70 kHz range used by these devices had no effect on reorienting flight by female mosquitoes either toward or away from human subjects. Additional tests have shown that sound generators capable of a wide range of frequencies were also ineffective in repelling mosquitoes. The fact is that these devices just do not work - marketing claims to the contrary.
The high quality version makes me feel a little bit better about my ears. I can hear only the *click* of 21.1 kHz (19.8 kHz, low-quality); I don't hear a significant constant beep until 19.8 kHz (15.8 kHz, low-quality).
legit can't hear until it hits 15.8 khz, but this has NOTHING to do with how old you are, I'm 19 years old, and my 51 year old mom can hear from 19.8 khz and 32 year old sister from 21.1 khz so.......
you actually can't hear the first few ones because there is no sound - the compression of the video, even with high quality, will remove it (mp3 compression removes frequencies inaudible to the human ear)
I'm a well-past 35 year old guy who's played electric guitar (loud!) for more than half my life. I heard the third one. I would be surprised if anyone (including kids) with an ipod could hear the first one.
I am 21 and heard every single Khz buzz, but I suffer from an acute hearing capability to electronic sounds. Every day I have to take a med to num out the sounds so I can sleep. If I dont take my prescription I can hear the electricity flowing threw my house which makes about a 15.8Khz buzz. I can even hear photos downloading into my laptop one by one from an SD card, and I can even tell you there is a pause between each picture download so I can even count each picture going in.
I didn't "hear" the first ones but I felt the vibrations In my ear definitely
