Changing The Shape Of Your Pinnas
改变你耳廓的形状
The pinnas are the distinctive 1 ridges 2 in your outer ear. Everyone has slight differences in the shape of pinnas. Researchers have theorized that the brain has to learn the shape of its own ears in order to hear correctly.
耳廓是外耳两边明显的脊状物。每个人的耳廓形状都略微有些不同。研究人员推理表示，要想听的更准确，大脑必须熟悉自己耳朵的形状。
New Pinnas
新的耳廓
So the brain should have to learn the shape of its own ears. By temporarily altering the shape of the pinnas with plastic molds, researchers in the Netherlands found that indeed, people with new pinnas had a hard time locating sound sources. After a few weeks of wearing the molds, however, their brains learned the new shapes of their ears and adjusted accordingly.
大脑必须熟悉自己耳朵的形状。通过对自愿参加试验的人们使用塑料模具临时改变他们耳廓的形状，荷兰的研究人员发现，这些参加试验人们确实难以确定声音的来源。但是，几周之后，他们的大脑就熟悉了带有塑料模具的新形状耳朵，并能够做出相应的调整。
After removing the molds, volunteers had no trouble readjusting. It seems that the brain remembered the shape of its real ears and didn’t have to relearn it.
去掉模具后，这些试验人员再次进行调整也比较容易。大脑似乎能够记得真正耳朵的形状，而不需要重新熟悉。
