Listen

Ok so I'm going to post a link below.
Its a sound test. All you have to do is listen to the sound and see if you can hear it. So far no one over the age of 40 has ever been able to hear it and losts of young people can't hear it either.
Whenever I listen to it my head kills because I have freaky hearing...to the point where I can hear dog whistles...yeah I know, freaky.
Anyways, take a listen and see if you can hear it. Lemme know in the comments section. x
