According to the International Union for Conrvation of Nature，33 percent of coral reefs（册瑚礁）are in danger.One of the victims is the Great Barier Reef in Australia，the world's largest coral reef system.
A team of British and Australian scientists banded and came up with a solution to revive one of the world's ven natural wonders.They ud underwater loudspeakers to attract fishes to the dead coral reefs to help them restore.The groundbreaking process is known as"acoustic（声音的）enrichment".
Loudspeakers are placed on patches of dead corals in the Great Barrier Reef.After careful obrvation，rearchers discovered a favorable result-nearly twice as many fish arrived-and stayed，as compared to parts where there was no sound from speakers.
"Healthy coral reefs are remarkably noisy places-the crackle of snapping shrimp and the whoop of fish combine to form a biological soundscape.Young fish home in on the sounds when they re looking for a place to ttle."said Professor Steve Simpson at the University of Exeter.
Reefs become quiet when they are decarded（退化），as the shrimps and fish disappear."By using loudspeakers to restore this lost soundscape，we can attract young fish back again."Simpson added."Fish are crucial for coral reefs to function as healthy ecosystems..Boosting fish populations in this way could help kick-
start natural recovery process，counteracting（抵消）the damage we're eing on many coral re
efs around the world."he said.
Despite this groundbreaking discovery，we still have our work cut out for the prervation of coral reefs.The average water temperatures are rising，and problems such as overfishing and pollution are still among the pressing issues at hand.Also，further rearch is still needed to understand how loudspeakers influence the behavior of aquatic（水中）creatures fully.
