The Mosquito noise is a high pitch sound that is undetectable to some and can be heard by others. Typically you lose the ability to hear higher pitched frequencies with age. It was originally used as a way to ward of teens and youth in Europe but then it was argued it went against Human Rights to do this.
I put together a series of 12 YouTube videos with the sound playing at increasingly higher pitches. I showed it to everyone at work and it was pretty interesting. Some could hear it almost to the end and one of my bosses couldn't even hear it at the lowest level (although it was irritating his wife as the video played).
Personally, I can hear it up to around 17 khz.
How far you can go before you stop hearing it?
