Ear between the outer ear and the inner ear. It consists of an air-filled cavity called the tympanic cavity and includes the three ossicles and their attaching ligaments; the auditory tube; and the round and oval windows. The ossicles are three small bones that function together to receive, amplify, and transmit the sound from the eardrum to the inner ear. The ossicles are the malleus (hammer), incus (anvil), and the stapes (stirrup). The stapes is the smallest named bone in the body. The middle ear also connects to the upper throat at the nasopharynx via the pharyngeal opening of the Eustachian
Anvil press to its tendency to transform into diamond. The DIA multi-anvil is the main alternative to the Kawai cell: it uses six anvils to compress a cubic sample. In principle, the multi-anvil press is similar in design to a machine press except that it uses force magnification to amplify pressure by reducing the area over which force is applied: This is analogous to the mechanical advantage utilized by a lever, except the force is applied linearly, instead of angularly. For example, a typical multi-anvil could apply 9,806,650 N (equivalent to a load of 1000 t) onto a 10 mm octahedral assembly,
