A buzzing sound in the ear is a symptom of tinnitus. Most tinnitus is a subjective tinnitus, a subjective sensation in which the patient can hear a sound in the ear but there is no corresponding sound source outside, and it is a manifestation of hearing dysfunction. There are many causes of tinnitus, including ear diseases that can cause tinnitus, physical factors that can cause tinnitus, and psychological factors that can also cause tinnitus. If a patient hears a buzzing sound, consider the possibility of secretory otitis media. If you hear an enhanced voice in your own speech, it may be related to the function of the eustachian tube. The specific situation needs to be clearly diagnosed after examination at the Department of Otolaryngology.
