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

Interestingly, the D (18.8kHz) is the hardest one for me to hear, and the C (16.7kHz) is the next hardest. C# (17.7kHz) and D# (19.9kHz) are both much clearer than their non-sharps.
