What We Can Learn From A Fly’s Ears
苍蝇的耳朵,启示多多

This may come as a surprise to you, but most flies don’t have theability to hear. However, certain parasitic flies have a hearing system that is so exact in pinpointing a sound’s origin that it rivals the exceptional ears of owls and cats.
你可能并不知道,大多数苍蝇听不到声音。但某种寄生蝇却拥有听力系统,不仅如此,他们还能准确地”定位”声源,其精确度堪比猫头鹰和猫那独一无二的听力。

This fly’s superb hearing surprised scientists because its tiny body is too small to use the same kind of hearing system that larger animals use. And yet they discovered that the fly was using its hearing to locate the chirps of crickets in order to then deposit parasitic larvae onto the crickets’ bodies.
这种寄生蝇卓越的听力“惊艳”到了一众科学家,因为寄生蝇那小小的身体根本用不了比他们大的动物的听力系统。科学家们还发现,寄生蝇为了将寄生的幼虫产在蟋蟀的身体上,可以用其强大的听力锁定蟋蟀的叫声。

What they found was unlike any other known ear structure, this fly’s eardrums are connected by a bridge of stiff material.
科学家的另一发现是,寄生蝇的耳朵结构与众不同,连接他们耳膜的”桥梁”质地坚硬。

Vibrations that travel between the two eardrums enable the fly to pinpoint the origin of a sound as accurately as any other sound system we know of.
两个鼓膜之间产生的振动使得寄生蝇能够锁定声源,其精确度堪比我们知道的任何声音系统。

And what’s more, this fly’s exceptional hearing system is influencing microphone and hearing aid technology. For instance, it could lead to hearing aids that hide within a person’s ear canal and yet are able to gather sound primarily from the direction the listener is facing.
此外,寄生蝇无与伦比的听力系统正影响着话筒和助听器技术。比如,它可以促进研发一种即可以隐藏在耳道内,又可以集中收集对面说话者的声音的助听器。
