A team of scientists says acoustic enrichment maybe able to help revitalize dead coral like what's found in some parts of the Great Barrier Reef. But what is acoustic enrichment? It's underwater loudspeakers and the music they play includes the sounds of healthy reefs. One of the authors of a study recently published in "Natures Communications", says healthy coral reefs are noisy places. They include the grunts of fish and the snaps of shrimp. But dead coral reefs are apparently much quieter without the hustle and bustle of undersea life.

一组科学家表示,丰富的声音可能有助于使死去的珊瑚恢复生机,就像在大堡礁的一些地方发现的那样。但什么是声学浓缩?这是水下扬声器,它们播放的音乐包括健康珊瑚礁的声音。最近发表在《自然通讯》上的一项研究的作者之一说,健康的珊瑚礁是嘈杂的地方。它们包括鱼的呼噜声和虾的啪啪声。但是,如果没有熙熙攘攘的海底生活,死去的珊瑚礁显然要安静得多。

So what scientists did was put speakers on dead coral patches of the Great Barrier Reef and play the sounds of healthy reefs. And they said that attracted fish about twice as many as areas of dead coral without the sounds. Researchers say the fish could help ecosystems recover and give the coral the chance of new life. The speakers aren't a proven solution at least not at this point. Scientists can't say for sure if the fish that the noises attracted actually stuck around.

所以科学家们所做的就是把扬声器放在大堡礁的死珊瑚上,播放健康的珊瑚礁发出的声音。他们说这吸引了两倍于没有声音的死珊瑚区域的鱼。研究人员表示,这种鱼可以帮助生态系统恢复,并给珊瑚带来新生命的机会。扬声器不是一个经过验证的解决方案,至少在这一点上不是。科学家们不能确定噪音所吸引的鱼是否还在附近。

That could be key to a reefs recovery. And they're hoping to do more research on this. But they think that the loud speakers could help. There are a number of threats to the health of coral reefs. They range from pollution and low tides to invasive species and changes in water temperature.

这可能是珊瑚礁恢复的关键。他们希望对此做更多的研究。但他们认为扩音器可能会有帮助。珊瑚礁的健康受到许多威胁。它们的范围从污染和低潮到入侵物种和水温的变化。
