The eustachian tube is involved in equalizing pressure between the middle ear and the throat, but it is not directly involved in sending a vibrational signal to the inner ear. The external auditory meatus (ear canal) helps direct sound waves towards the eardrum (tympanic membrane), which begins the process of transmitting vibrations. The malleus (hammer) is one of the three small bones in the middle ear that transmit vibrations from the eardrum to the inner ear. The stapes (stirrup) is the last of the three small bones in the middle ear and transmits vibrations to the oval window, which leads to the inner ear.
