I had tinnitus 9 years ago took a year and a half to go away it was from antibiotics and to point i couldn't hear it anymore i forgot i had it last 5 years .. this acoustic trauma is a whole new ball game for me.. the old tinnitus is active again like a electrical pulse that drives up the new tinnitus with it turning it into a cricket dying sound how i think it sounds pulsing cricket .. im only 36 days into it
