So basically, these three bones act as a lever system. And as the force is transmitted from the Malleaus to the incas, to our staples, our force increases as a result of that decrease in the lever arm, decrease in our displacement. And so that means we also have an amplification process taking place within this lever system. And the force that is created by that pressure weight is increased as we go along these three bones. So we have amplification taking place at the pinnam, we have amplification taking place at the eardrum, and we have amplification taking place at these three octaves, at these three bones. The question is, why exactly do we want this amplification to take in the first place?
