When can you hear this?...if at all?

Can you hear this?



This is what is called a mosquito alarm, supposedly only teens can hear it. I could only hear it at about 12khz, how about you?

UPDATE: After Jon S. mentioned something in the comments I gave this a listen at home and could hear it at 14.1, so maybe it does have to do with the speakers? Anyone else have anything to add?

I tried this with each of the children and each one could only begin to hear it at 12khz - me too. AFGG

I think also said that you had to be a certain age to hear the higher tones, maybe that is why the kids could not hear it...who konws. Any other viewpoints out there?

I wonder if the quality of your sound card and speakers makes a difference. My 10 year old son and I both heard it loud and clear at 12 khz, but nothing before that.
