Tinnitus or teen?

[grammarwoman]

You are the typical teenager

You can hear the frequency of the mosquito teen repellent - but probably not for much longer! The highest pitched ultrasonic mosquito ringtone that I can hear is 17.7kHz

I might have been able to hear higher, but there's so much background noise and interference going on here at work (don't get me started on the crack-smoking architecture) that I couldn't be sure.
