Fr peple, wh are interested in sund, the field f sund technlgy is definitely making nise. In the past, sund engineers wrked in the back rms f recrding studis, but many f tday’s sund prfessinals are sharing their knwledge and experience with prfessinals in ther fields t create new prducts based n the phenmenn we call sund.
Sund can be used as a weapn. Imagine that a plice fficer is chasing a thief. The thief tries t escape. And the fficer can’t let him get away. He pulls ut a special device, pints it at the suspect, and switches it n. The thief drps t the grund. This new weapn is called a Lng Range Acustic Device（LRAD, 远程定向声波发射器）. It prduces a deafening sund s painful that it temprarily disables a persn. The nise frm the LRAD is directed like a ray f light and travels nly int the ears f that persn, but it is nt deadly.

Simply turn the machine n pint it at the target, and yur peace and quiet cmes back.
Directed sund is a new technlgy that allws cmpanies t use sund in much the same way sptlights（聚光灯）are used in the theater. A sptlight lights up nly ne sectin f a stage; similarly, a "sptsund" creates a circle f sund in ne targeted area. This can be useful fr businesses such as restaurants and stres because it ffers a new way t attract custmers.
