Tiny fish as loud as a pneumatic drill 研究人員發(fā)現(xiàn)一種小魚發(fā)出的聲響音量堪比風(fēng)鉆
德國(guó)柏林的科學(xué)家們發(fā)現(xiàn)，一種透明小魚發(fā)出的聲音和風(fēng)鉆的音量一樣響。
This buzzing, chirping sound is the pulsing chatter of the tiny transparent Danionella cerebrum as heard by the human ear. Researchers in Germany were intrigued by the noise coming from the fish tanks in their lab and decided to investigate the source. Using underwater microphones, they quickly deduced that this species was no small fry when it came to communication.
你聽到的這種嗡嗡的嘰喳聲是一種學(xué)名為 “Danionella cerebrum” 的透明小魚的脈沖聲。德國(guó)的研究人員們偶然聽到了從實(shí)驗(yàn)室的魚缸中發(fā)出的噪音，對(duì)此很感興趣，所以決定找出這個(gè)噪音的來(lái)源。通過(guò)利用水下麥克風(fēng)，研究人員很快就推斷出，就交流方式而言，這個(gè)魚類物種絕不可小覷。
This is the slowed down sound booming out like a heartbeat. The fish uses its muscles to strike its own swim bladder to produce a short loud sonic pulse. In the waters close to the fish, it taps out 140 decibels, which is as loud as a gunshot.
這段經(jīng)調(diào)慢處理后的音頻播放的是這種透明小魚發(fā)出的像心跳一樣低沉有力的聲音。它們牽動(dòng)自身肌肉沖擊體內(nèi)的魚鰾，從而發(fā)出一個(gè)短暫而響亮的聲波脈沖。在靠近這種透明小魚的水域內(nèi)，可以探測(cè)到它們發(fā)出高達(dá) 140 分貝的聲音，如槍聲一樣響亮。
Researchers believe this quirky communication behaviour evolved in the murky streams in Myanmar, where the fish lives. Other fish, including the Plainfin Midshipman, and the Black Drum are louder, but also much bigger creatures.
研究人員們認(rèn)為這種奇特的交流行為是在緬甸渾濁的溪流中進(jìn)化得來(lái)的，那里是它們的棲息地。其它魚類，包括斑光蟾魚和多須石首魚發(fā)出的聲音更響亮，但它們的體型也更大。

答案
1. In which country was the sound made by the fish discovered?
Researchers in Germany discovered the sound made by the fish.
2. How does the fish produce the sound?
The fish produces the sound by using its muscles to strike its own swim bladder.
3. How loud is the sound?
The fish makes a sound that is 140 decibels – as loud as a gunshot.
4. True or False? Danionella cerebrum is the loudest fish.
False. Other fish, including the Plainfin Midshipman and the Black Drum are louder.
