韩国最大的移动电话运营商表示他们将向手机用户提供一项全新的干扰音服务，他们称，这项服务是用来驱蚊的。

　　韩国鲜京电讯公司表示，定制此项服务的用户只需花3000韩元（合2.50美元）便可下载一种声波。这种声波可以在三英尺的范围内驱赶蚊虫，而人耳却听不见。用户只需按几下手机按键便可播放该声波。

　　The company claimed that the service worked during tests.

　　该公司宣称此项服务在测试中运行良好。

　　The service, which begins Monday, has one drawback: it consumes as much battery power as normal cell phone rings.
