Which part of the ear communicates vibrations to the inner ear?

Explanation:
Vibrations are transmitted to the inner ear through the middle ear. The tympanic membrane (ear drum) vibrates in response to sound, and those vibrations are passed along by the three tiny bones—the hammer, anvil, and stirrup (the ossicular chain). This lever system transfers the energy to the oval window of the cochlea and amplifies it, overcoming the mismatch between air and fluid. The movement of the oval window then creates waves in the cochlear fluids, stimulating hair cells that convert the mechanical energy into neural signals sent to the brain.
