    Changing The Shape Of Your Pinnas
    The pinnas are the distinctive ridges 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.
    New Pinnas
    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.
    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.
    改變你耳廓的形狀
    耳廓是外耳兩邊明顯的脊?fàn)钗?。每個(gè)人的耳廓形狀都略微有些不同。研究人員推理表示，要想聽(tīng)的更準(zhǔn)確，大腦必須熟悉自己耳朵的形狀。
    新的耳廓
    大腦必須熟悉自己耳朵的形狀。通過(guò)對(duì)自愿參加試驗(yàn)的人們使用塑料模具臨時(shí)改變他們耳廓的形狀，荷蘭的研究人員發(fā)現(xiàn)，這些參加試驗(yàn)人們確實(shí)難以確定聲音的來(lái)源。但是，幾周之后，他們的大腦就熟悉了帶有塑料模具的新形狀耳朵，并能夠做出相應(yīng)的調(diào)整。
    去掉模具后，這些試驗(yàn)人員再次進(jìn)行調(diào)整也比較容易。大腦似乎能夠記得真正耳朵的形狀，而不需要重新熟悉。
