The mosquito device was made for the likes of you. You are probably begging to make the noise stop! The highest pitched ultrasonic mosquito ringtone that I can hear is 18.8kHz |

Dear Doctor Genge.
I hereby offer myself as a study subject. I've been told this:
"You are a dog
Or maybe you are a mosquito, you certainly can't be human.
The highest pitched ultrasonic mosquito ringtone that I can hear is 21.1kHz"
