Do Mosquito Ringtones Really Work?
The mosquito ringtone, which is a ringtone geared toward especially high frequencies that only young people can hear is really catching on in schools, clubs, or other places where children and teens want to use cell phones surreptitiously. This type of ringtone is also called the “adult proof ringtone” and with good reason.
The range of human hearing starts to fade for most of us around age 20, while teens retain the ability to hear the highest pitch of sound in the normal human range. What this means is that most teens can hear sounds that 90% of adults simply can’t hear at all. Even if adults can perceive the sound, it generally registers as a slight pressure in the head, or as a soft popping noise. Turning this sound into a ringtone means that children and teens can hear phone calls and incoming text messages, without a teacher or parent being aware.
“So what not just put the phone on vibrate?” Some ask, after learning about mosquito ringtones. After all, it seems sort of complicated to assign a non-audible ringtone, when a vibrate function would be just as good. Teens know the answer to this. When vibrate is turned onto a phone, it’s still audible – especially if it has something to vibrate against, like a desk or a book. The beauty of the mosquito ringtone is that it doesn’t vibrate, and can’t be heard at all by anyone who is significantly older.
Still there’s a lot of skepticism about how well these ringtones really work. If a kid can hear it, what about a parent with exceptional hearing?
The truth is that up to 90% of adults can’t hear sounds between 18-20 khz, while up to 70% of those younger than the age of 17 can. This means that there are very good odds of ensuring that a mosquito ringtone audible to a teen won’t be heard by an adult. Of course, there will always be some rare exceptions, but there’s a good chance that someone using a mosquito ringtone will be able to use it in secret.
The beauty of a ringtone that adults can hear is also that they are not expecting it. When adults can hear a high pitched frequency, they often assume it’s due to fluorescent lighting, or to an old TV or computer monitor. These kinds of monitors did once emit high pitched noises, before largely being phased out in favor of flat panel LCDs. This means that even if an adult can hear a mosquito ringtone, they will have a very hard time determining its origin, or knowing that it’s coming from a cellular phone. This gives children and teens a huge advantage.
So do mosquito ringtones work? They absolutely do. Still, it’s a good idea to test out a range of pitches and frequencies to ensure that the tones you can hear are really inaudible to the older people around you.

The problem is that when one of these ringtones goes off during class, it’s obvious as hell. 16+ khz is downright painful so every other kid in the room will glare at you and tell you to turn the damn thing off. Not very subtle.

I’m 39 and an ICT teacher. My hearing is pretty good, but I can’t hear above 17kHz… however, my phone can. Don’t use it in my class kids, you’ll get busted.

For audiophiles, this “phenomenon” is most likely the reason why some component stereo and speaker manufacturers do not bother trying to engineer their products to max out above 16KhZ.

Why do you need to text in class so badly anyway? Those ringtones are also very annoying and screw your cellphone’s speakers. I’m not going to sacrifice my phone’s speakers so I can text in class…

This is excellent..but too bad the kids don’t use it to their advantage..i.e. putting it to good use by listening to teachers/parents- and learning something other than Xbox!

The problem is that your teachers are not all older adults. I am 23 and teach high school and middle school. I definitely caught one of my students using a high pitched ring tone today, and I can hear all but the most high-pitched sounds. And since these were around 8 years ago when I was in high school, I won’t confuse it for the lighting.
