And that's exactly we amplify the force at the pina. We then amplify the force at the ear drum, and we amplify the force at our three bones, the malleus, the incas, and the staples. Now, at the pina, we amplified by about times two. At the eardrum, we amplified by about times 15. And at these three bones, we amplified by about times three. So together we amplified by two times 15, times three.
