ATC SUPPORTS U.S. ARMY WITH LRAD DEPLOYMENTS IN IRAQ

SAN DIEGO--(BUSINESS WIRE)--Dec. 15, 2004--American Technology Corporation (ATC)
(NASDAQ:ATCO - News), an innovator of proprietary sound reproduction
technologies, announced today it has been awarded a new order totaling
$4,899,000 for its proprietary Long Range Acoustic Devices (LRAD(TM)). The
contract, calling for immediate deliveries this month and in early January, will
support the U.S. Army's 3rd Infantry Division deploying in support of Operation
Iraqi Freedom.

Regarded as the Army's most technologically advanced division, the 3rd Infantry
Division will be utilizing LRADs in Iraq for crowd control, area denial and
clearing buildings. The immediate deliveries will also support the division's
mission to provide security for the Iraqi elections scheduled for late January
2005.

LRAD is a breakthrough long-range hailing and warning, directed acoustic device
designed to communicate with authority and exceptionally high intelligibility in
a 15-30 degree beam. LRAD can issue a verbal challenge with instructions in
excess of 500 meters and has the capability of following up with a warning tone
to influence behavior or determine intent. LRADs are currently deployed with the
U.S. Marine Corps, U.S. Army, and U.S. Navy in Operation Iraqi Freedom in and
around Fallujah, Mosul, and the port of Basra.

"It is clear," stated Senator Olympia Snowe, U.S. Senator (R-ME), "that the Long
Range Acoustic Device represents a new breakthrough in non-lethal capability.
This order affirms the intent of Congress to provide the best possible emerging
technologies for the effectiveness and safety of our service men and women."
"LRAD supports the unique challenges of military operations, law enforcement and
infrastructure protection," commented Carl Gruenler, ATC's vice president of
government and force protection systems.

"LRAD addresses the urgent and compelling need to place distance between
peacekeepers and a potential threat, provides crystal clear instructions in host
nation language to clarify purpose and intent, and creates safe situations out
of uncertain ones."

Continued Gruenler, "This order also reflects an expanding partnership between
VoxTec, a division of Marine Acoustics and ATC. VoxTec has developed the
Phraselator, a hand-held voice translation device, which is a key tool to store
and immediately retrieve thousands of messages recorded by the Defense Language
Institute for transmission through LRAD at extended ranges in the host nation
language. This capability is being implemented with each LRAD delivered in this
order and augments ATC's hardened MP3 player used for messaging and
instantly-available aversive warning tones."

Gruenler concluded, "This and other expected LRAD orders are providing evidence
that our proprietary, long range hailing and warning device is expanding its
worldwide leadership position for military, government and commercial customers
as The Sound of Force Protection(TM)."
