American Technology's LRAD-R® Takes Center Stage at 53rd Annual ASIS International

LRAD-R Being Showcased This Week to Public and Private Security Professionals

SAN DIEGO, CA--(Marketwire - September 24, 2007) - American Technology Corporation (ATC) (NASDAQ: ATCO), a leading innovator of security and military directed sound products and technologies, today announced that its proprietary LRAD-R® is being showcased this week (September 24 - 27) in Las Vegas at ASIS 2007, The Epicenter for Breakthrough Security Solutions. More than 23,000 security professionals from around the world are expected to attend ASIS 2007, which features the latest cutting-edge technologies, products and services from over 950 exhibiting companies. LRAD-R will be featured in ATC's Booth #676, at L-3 Communications' Booth #2659 and at QuickSet's Booth #137.

Developed for military force protection, LRAD-R uses its directionality and focused acoustic output to clearly transmit critical information, instructions and warnings well beyond 500 meters. Through the use of powerful voice commands and deterrent tones, large safety zones can be created while determining the intent and influencing the behavior of an intruder.

LRAD-R can be operated remotely across an IP network enabling system operators to respond to potential threats from a safe environment while creating a complete unmanned perimeter security solution. LRAD-R accepts intruder position information from other IP-enabled sensor systems to automatically find and track potential threats. LRAD-R's large safety zone gives security personnel additional time and valuable information if an elevated intruder response becomes necessary.

"LRAD-R security operators can now turn a passive surveillance network into an active defense system that can locate, track, communicate with, and deter an intruder," said Tom Brown, ATC's president and chief executive officer. "Our system is ideal for port and border security, enforcement of exclusion zones around oil and gas platforms and pipelines, perimeter security for petrochemical and nuclear plants, and many other areas which require critical infrastructure protection."

LRAD-R features an emitter head, integrated camera, high-intensity searchlight (optional) and full pan and tilt capability for precise aiming and tracking. Audio output from ATC's LRAD-R is highly directional so nearby personnel and system operators are not exposed to excessive audio levels, while still providing exceptional voice intelligibility and tonal clarity over long distances. Because of its automated capabilities, LRAD-R reduces manpower and false alarms while providing a more effective and cost-efficient security solution.

"LRAD-R has been specifically designed for use in a variety of security environments where low maintenance, trouble-free operation is a must," Brown concluded. "LRAD-R is a necessary and significant security upgrade for valuable infrastructure and securing perimeters."
