1 When the bones of the middle ear do not vibrate and become stiff, it can give rise to a hissing and vibrating sound in the ears. 2  Rupture of ear drum either due to trauma or due to loud sound can cause vibration in the ear during the initial stage. 3  Infection in the ear, cold and sinusitis can also cause vibration.
Sound causes the eardrum and its tiny attached bones in the middle portion of the ear to vibrate, and the vibrations are conducted to the nearby cochlea. The spiral-shaped cochlea is part of the inner ear; it transforms sound into nerve impulses that travel to the brain.The fluid-filled semicircular canals (labyrinth) attach to the cochlea and nerves in the inner ear. They send information on balance and head position to the brain. Otitis media (middle ear inflammation): Inflammation or infection of the middle ear (behind the eardrum). 2  Usually, this is caused by an infection. 3  Swimmerâs ear (Otitis externa): Inflammation or infection of the outer ear (pinna and ear canal).
