機場鳥擊問題在全球航空業已經造成好幾百萬美元的損失，研究人員終於發現防範之道。
鳥擊對全球航空業都是很嚴重的問題，1988年到2013年間更造成255人死亡。
傳統上應對鳥擊的方法包括射鳥、毒鳥、捕鳥和用狗嚇牠們，但這些方法的效率都不怎麼高。
為了找出把鳥兒嚇離機場的高科技方法，維吉尼亞州威廉瑪麗學院（College of William and Mary）的研究人員在一條跑道附近，設置了一個聲波網特區。
裡面有擴音器和音箱，會播放分貝介於家用洗碗機和熙攘餐廳之間的噪音。
這種噪音會打斷鳥兒之間的溝通，迫使牠們轉移陣地。
這項實驗進行後也發現，該跑道附近的鳥類數量，已經因為聲波網而減少八成。
研究人員說目前沒有跡象顯示，這些鳥兒會適應聲波網產生的噪音，代表這個做法或許能用上很長一段時間。

Researchers have found a new way to prevent bird strikes at airports, a problem that has cost the aviation industry billions of dollars worldwide.
Bird strikes are a serious problem for the global aviation industry ... and are blamed for 255 human deaths between 1988 and 2013.
Traditional methods to tackle bird strike including shooting, poisoning, scaring them with dogs and capturing them. However, none of these methods are highly effective.
Looking for a high-tech method to scare birds away from airports, researchers in Virginia set up a sonic net zone near an airstrip.
It had speakers and amplifiers emitting noise between the decibel levels of a domestic dishwasher and a busy restaurant.
The noise disrupted bird communication and forced them to go elsewhere.
The experiment found that 80 percent of the bird population near the airstrip area was reduced as a result of the sonic net.
Researchers said there was no sign of the birds becoming habituated to the noise generated by the sonic net, meaning the method could remain effective for a long period of time.
