High-tech sound may drive development for LRAD (formerly American Technology Corporation), but the firm is also banking on it to drive its bottom line. LRAD, whose past sales largely came from its portable radios, discontinued its portable consumer electronics division to make products that transmit sound over short and long distances. The company's Long Range Acoustic Devices generate the majority of revenues nowadays, and they have been deployed by the US military and used by public safety agencies worldwide. To strengthen its identity as a global provider of long-range acoustic technology systems, the company changed its name to LRAD in 2010.
