Question: why is it that sometimes you randomly hear a high pitch ringing noise


  1. It’s called tinnitus, and it can be caused by muscle movement close to the ear, changes in the ear channel or blood flow in the face or neck or all sorts of other things.

    Here is some more information on tinnitus.


  2. Yep, tinnitus. We still don’t know all there is to know about tinnitus. Some of my neuroscience friends in my building are interested in tinnitus, what causes it and how to treat it better.
    It seems to be the little hair cells in your cochlea being inappropriately stimulated to make you think you are hearing a noise. This can be caused by damage to these cells-try and look after your ears and don’t have your earphones up too loud!
