Only after your brain accepts these signals and translates them into sounds are you able to hear them. Sometimes, your inner ear sustains damage, altering the way your brain processes sound.
Damage to your eardrums or the tiny bones in your middle ear can also interfere with the proper conduction of sound. Tumors in the ear or on the auditory nerve may also cause ringing in the ears.
