It is caused by abnormal blood flow within the arteries of the neck or inside the ear, and is fairly rare. Possible causes include: Fluid in the middle ear, Ear infections., High blood pressure, Head and neck tumors, Blocked arteries. Nonpulsatile tinnitus – ringing in the ears not accompanied by any type of rhythm – is considerably more common. It can be caused by a variety of conditions including: Presbycusis (age-related hearing loss), Noise exposure, Impacted earwax.
Otosclerosis (stiffening of the bones in the middle ear), Meniere’s disease, TMJ disorders, Ototoxic medication, Thyroid conditions, Head or neck trauma, Acoustic neuromas. Tinnitus is also classified as being either subjective (heard only by the patient) or objective (ringing can be heard by an impartial observer, such as a doctor). Most cases of tinnitus are subjective in nature.
