Try tinitus.<br><br>It's on <b>every</b> video.,(reply>), @Massimo O'Kissed My Tinnitus is 13,500 hz 24/7. Is your Tinnitus chronic too? Does it bother you anymore? Take care,(reply>), @baseballlive77 I once crudely measured it myself, using an oscilloscope and a freq gen until the pitch sounded the same, and it was about 8kHz.,(reply>), You have Tinnitus too?
