Sentence 55 So musical instruments evolved in ways that optimize their acoustical properties--how the instrument vibrates and sends those vibrations through the air to our eardrums.

因此乐器的演变方式就是优化它们的声学特性，即乐器如何振动，以及如何将所产生的振动通过空气传到我们的耳膜。

" It works on the same principle, so it detects noise that's coming into the windows and then is cancelling the noise." Bhan Lam, an acoustical engineer at Nanyang Technological University in Singapore.

“它的工作原理相同，因此它会检测进入窗户的噪音， 然后消除噪音。 ” 新理工大学的声学工程师 Bhan Lam 说。
