Tinnitus is the perception of sound when there is no external sound stimuli, it is most described as a ringing, but it may also sound like a clicking, buzzing, hissing or rumbling/roaring sound. It can range in volume and pitch, and can be heard in one or both ears. The causes can range from earwax build-up, to head injuries, to noise-induced hearing loss.
Tinnitus is most noticeable when it is quiet. It is linked with attention and when there are everyday sounds around, they draw your brain’s attention away so the tinnitus is not as noticeable.
