Five of the Loudest Animalsin the World 世界上聲音最大的五種動(dòng)物

Kristen Hall-Geisler 楊舟選譯

When the sun rises early in the morning and youre snuggled1 under thecovers， the loudest animal in the world is probably your cat or your dog begging2 forbreakfast.

當(dāng)大清早太陽(yáng)升起而你蜷縮在被窩里時(shí)，世界上聲音最大的動(dòng)物可能是你家討要早餐的貓或狗。

However， scientists have actually measured the sounds made by animals in thewild. They too are very， very loud， and maybe even louder than your pets in themorning.

然而，科學(xué)家實(shí)際上測(cè)量了野生動(dòng)物發(fā)出的聲音。它們也非常響亮，可能會(huì)比清晨時(shí)你的寵物更大聲。

1. Tiger Pistol Shrimp

Pow pow！ This little shrimp doesntmake sounds with its mouth. It uses itshuge claw3 to shoot jets4 of water withsuch force that it creates an air bubble.When this bubble implodes5， it generatesa shockwave thats been measured atmore than 200 decibels6. This shockwavecan kill other shrimp as far as 2 metersaway. Human eardrums7 will rupture8 at160 decibels. Thats some shrimp！

1. 老虎槍蝦

砰砰！這種小蝦的嘴不會(huì)發(fā)出聲音。它用巨大的鰲夾射出水柱，其力量之大足以制造出一個(gè)氣泡。當(dāng)這個(gè)氣泡破裂時(shí)，它會(huì)產(chǎn)生一個(gè)超過(guò) 200 分貝的沖擊波。這種沖擊波可以殺死 2 米開(kāi)外的其他蝦。人的耳膜會(huì)在 160 分貝時(shí)破裂。而那是某種蝦！

2. Blue Whale

This loudest animal in the world is alsothe largest animal in the world. The bluewhales call can reach 188 decibels. Weshare the planet with blue whales and tigerpistol shrimps， so how do we even haveeardrums if these animals are so loud？ Wereprotected by the fact that they liveunderwater and we do not. If we did live inthe sea， wed be able to hear the song of theblue whale as far as 1，609 kilometers away.

2. 藍(lán)鯨

這種世界上聲音最大的動(dòng)物也是世界上體型最大的動(dòng)物。藍(lán)鯨的叫聲可以達(dá)到 188 分貝。我們與藍(lán)鯨和手槍蝦共享這個(gè)星球，那么如果這些動(dòng)物的聲音如此之大，我們?cè)趺磿?huì)有耳膜呢？它們生活在水下而我們沒(méi)有，我們因此受到了保護(hù)。如果我們真的生活在海里，我們就能在 1，609 公里之外聽(tīng)到藍(lán)鯨的歌聲。

3. Greater Bulldog Bat

The greater bulldog bat， usesecholocation9 to find food， like all bats. Butthese bats feed on fish. That means theyneed to emit10 a sound that can penetrate11both air， where they fly， and water， wheretheir food swims. Their echolocation call canreach 140 decibels. But we humans getlucky again in sharing the world with thesebats， since these loud sounds are outside therange of human hearing.

3. 兔唇蝠

兔唇蝠與所有蝙蝠一樣使用回聲定位來(lái)尋找食物。但這些蝙蝠是以魚(yú)為食。這意味著它們需要發(fā)出一種聲音，既能穿透它們飛行的空氣，也能穿透食物游動(dòng)的水。它們的回聲定位聲波可以達(dá)到 140 分貝。與這些蝙蝠共享這個(gè)世界的我們?nèi)祟愒俅巫哌\(yùn)了，因?yàn)檫@些響亮的聲音超出了人類的聽(tīng)覺(jué)范圍。

4. Kakapo

Our next loudest animal is also theloudest bird， the kakapo. This New Zealandnatives call can be as loud as 132 decibels.The flightless kakapo holds a couple of otherrecords， too. Its the heaviest parrot speciesin the world. And its the longest -livedbird—theyre known to reach their 90thbirthday.

4. 鸮鸚鵡

我們下一個(gè)聲音最大的動(dòng)物鸮鸚鵡也是聲音最大的鳥(niǎo)類。這種原產(chǎn)新西蘭的動(dòng)物叫聲可以高達(dá) 132 分貝。不會(huì)飛的鸮鸚鵡也保持著其他的記錄。它是世界上最重的鸚鵡種類，也是壽命最長(zhǎng)的鳥(niǎo)———已知可達(dá) 90 歲。……
