Why can you hear the roar of the ocean waves when you hold a seashell up to your ear？ The best explanation for that sound is the noise from around you. The seashell that you are holding captures[7] this noise， which resonates[8] inside the shell. The size and shape of the shell has

some effect on the sound you hear. You can produce the same “ocean” sound using an empty cup or even by cupping your hand over your ear.

為什么把貝殼放在耳邊會聽到海浪的聲音呢？最好的解釋就是，這聲音來源于環(huán)境噪聲。你拿著的貝殼會捕捉到環(huán)境噪音，并在殼內產(chǎn)生共振。貝殼的大小和形狀都會對你聽到的聲音有一定的影響。如果你用一個空杯子替代貝殼或直接用手罩住耳朵，也會聽到類似的“海洋”的聲音。
