What are some of the causes of a popping noise in the ear?

Causes of tinnitus or noise in the ear include age-related hearing loss, ear bone changes, earwax blockage, exposure to loud noises and temporomandibular joint disorders, notes Mayo Clinic. There are several medications that may cause or make tinnitus worse, including antibiotics, aspirin, diuretics and cancer medications.

Tinnitus is unusual sounds that occur in one of the four sections of the ear, including the outer ear, inner ear, middle ear and brain, says MedicineNet. Tinnitus is not an illness but a symptom. Symptoms related to tinnitus include anxiety, depression, ear pain and stress. Unexplained tinnitus that is experienced for an extended period of time is evaluated with an audiogram.
