Possible causes of noises in the ears without an outside sound source include middle, inner ear or eardrum damage; ear tumor; excessive earwax; or regular exposure to incredibly loud sounds, according to Healthline. Hearing loss or taking certain medications can also lead to tinnitus, the medical term for ear noises.
People with tinnitus hear varying types of noises, such as ringing, whistling, buzzing or roaring, states Healthline. Some people experience tinnitus in a single ear, while others hear noises in both ears. Older adults commonly develop tinnitus.
Subjective tinnitus is a common type of tinnitus in which a person is the only one who can hear certain noises in his ears, explains Healthline. A rare type of tinnitus is objective tinnitus, in which a person may hear a noticeable noise in his ears, particularly a noticeable pulsing sound related to his heartbeat, that others can hear as well. Objective tinnitus typically results from the presence of abnormal blood vessels in and around the ears.
People who frequently listen to loud music often experience temporary tinnitus, notes Healthline. Construction workers who use noisy, heavy equipment are also prone to developing the condition. Moreover, a link exists between tinnitus and stress, anxiety and depression. Medications that can lead to tinnitus include anti-malaria drugs, antibiotics such as erythromycin, diuretic medications, large doses of aspirin and certain cancer drugs.
