The Path of “Sound”
... When sound waves from the world outside strike the eardrum, it vibrates. These vibrations from the eardrum pass through the three bones of the middle ear and into the inner ear through the oval window. Action of the oval window causes fluids in the cochlea to create waves where they disturb the basi ...

Functions of the Sense Organs
... Acoustic energy, in the form of sound waves, is channeled into the ear canal by the pinna. Sound waves strike the tympanic membrane, causing it to vibrate like a drum, and changing it into mechanical energy. The malleus, which is attached to the tympanic membrane, starts the ossicles into motion. ...
