This Anti Mosquito repellent application emit a very unique high frequency sound (ultra sound) that most mosquitoes find distasteful and prevents you from getting bitten by mosquitoes.
The pitch of the sound is so high that most humans will not notice anything.
The problem is that the idea isn't new or untested. In fact, ultrasonic repellants that claim to work on the same principal have been around for decades.
