Possible causes of tinnitus, which refers to unusual buzzing or ringing noises in the ears, include an ear infection, ear wax, a foreign object in the ear and hearing loss, according to MedlinePlus. Caffeine, alcohol and drugs, such as aspirin and antibiotics, are also potential causes of tinnitus.
Many people experience mild tinnitus for a few minutes only, although some individuals notice recurring noises that make it difficult for them to rest or concentrate, notes MedlinePlus. These noises do not come from the surroundings, and they usually sound like whistling, humming, hissing, blowing or roaring.
Tinnitus can indicate Meniere's disease, which is an inner ear disorder that also causes hearing loss and lightheadedness, says MedlinePlus. It can also signal an allergy, anemia or high blood pressure. In rare cases, tinnitus is a symptom of a severe condition, such as aneurysm or a tumor.
Home remedies for tinnitus include calming music and low-level sounds that make the buzzing and ringing less noticeable, such as a white-noise machine, humidifier or ticking clock, notes MedlinePlus. People with tinnitus should avoid loud environments, smoking, and drinking alcoholic and caffeinated drinks. Anyone who hears noises following a head injury or experiences symptoms such as vomiting or nausea should consult a doctor immediately.
