Most people describe tinnitus as a ringing sound. But it can also sound like:
Buzzing
Hissing
Clicking
Whooshing (often related to blood flow)
Roaring
A high-pitched whine
A low-pitched hum
The sound can be constant or intermittent. It can be in one ear, both ears, or feel like it’s coming from the center of your head. It can be barely noticeable or loud enough to interfere with hearing real sounds.
