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.
1 The eardrum vibrates because of the soundwaves. 2  This vibration is picked up by the ossicles and transmitted through the middle ear to the oval window. 3  Therefore it is the soundwaves causing the eardrum to vibrate that ultimately makes the ossicles vibrate.he stapes (aka stirrup) is the smallest of the three auditory  ossicles of the middle ear. These little bones amplify and  transmit sound vibrations from the tympanic mem â¦ brane (eardrum) to  the oval window. The stapes is in direct contact with the oval  window. F J Eagle.
