Document Summary

There are three dimensions: loudness: how large the amplitude of the sound wave is. At the high points, air is compressed and at the low points, air is rarefied. The different between these two points is the amplitude: pitch: the frequency of the sound waves. That is, the amount of times a wave hits a particular point (such as its peak) in one second. Measured in hertz: timbre: the complexity of the wave, what goes into making it, the details. So, along with vibration, it also protects your middle ear. So it"s pretty tough, meaning it won"t vibrate quite as well as it could and so called ossicles. )t"s a mechanical (cid:498)membrane behind the oval window(cid:499), then it enters the cochlea: the first bone is called the malleus, then the incus, then the stapes, the stapes then knocks against another membrane called the. The rest of the channels were filled with air.
