"The middle ear is like an amplification chamber. When a sound wave vibrates the ear drum ), the sound is transmitted by the little bones to the inner ear and then the nerve impulse is sent to the brain. "
"The middle ear is like a biconcave lens. It is filled with air and houses the malleus, incus and stapes, which transmit sound waves from the tympanic membrane "
"If hearing is like a road, with the sound at one end traveling down the road to the brain, the middle ear is like a tunnel that the road travels through. It connects the outside and the inner ear."
"For the ear, which is a transducer of sorts, there are several transformers of note. The ear drum changes acoustic energy to mechanical. The middle ear is like a series of levers that acts as a pure-mechanical transformer. The end of these levers connect to the inner ear where it transforms again into acoustical energy."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
