Ear ringing, also known as tinnitus, is the perception of sound in the ears or head without an external source. It can manifest as a ringing, buzzing, hissing, or clicking noise. Tinnitus can be temporary or chronic and may vary in intensity. Common causes include exposure to loud noises, ear infections, and age-related hearing loss. While tinnitus itself is not a disease, it can be a symptom of an underlying condition. Treatment options vary and may include sound therapy, hearing aids, or counseling. Managing stress and avoiding loud environments can also help reduce the severity of symptoms.
