The eustachian tube is involved in equalizing pressure between the middle ear and the nasal cavity, but it is not involved in sending a vibrational signal to the inner ear. The external auditory meatus is the pathway for sound waves to travel to the eardrum, the malleus is one of the three small bones in the middle ear that transmits sound vibrations from the eardrum to the inner ear, and the stapes is the smallest bone in the human body and transmits sound vibrations from the malleus to the inner ear.
