MOSQUITO SHUT OUT

Are you annoyed with mosquitoes flying arround?
Well Shout Out all of them with a click of a button!
How it work? Well dragonflies are the mortal enemy for mosquitoes and in flight they generate sound frequencies (approximately) between 67Hz and 45Hz, depending on their sizes.
Your iPhone will work well for this purpose generating a swipe sound ranging from the frequency anbove. Most humans cannot hear this sound, but depending on your "age" you may hear a little noise, however its not harmful to you!
The sound level on the speakers shoud be adjusted so it is barely audible.
