                      AMERICAN TECHNOLOGY ANNOUNCES REVENUE
                      RESULTS FOR FIRST FISCAL QUARTER 2004

              COMPANY FORECASTS FURTHER REVENUE GROWTH FOR QUARTER
                              ENDING MARCH 31, 2004


(SAN DIEGO, CALIFORNIA - FEBRUARY 12, 2004) - AMERICAN TECHNOLOGY CORPORATION
(NASDAQ: ATCO) today announced revenue results for the first quarter of fiscal
2004, ended December 31, 2003. Revenue for the quarter was $774,778 compared to
$423,299 in the first quarter of fiscal 2003, an 83 percent increase. First
quarter revenues represented 59 percent of revenues for the entire year of
fiscal 2003 that ended September 30, 2003. The Company reported a gross profit
of $366,300 compared to a gross profit of $101,664 for the same quarterly period
in fiscal 2003. The Company also reported a net loss of $1,136,427, a 34%
reduction compared to the net loss of $1,731,645 for the same period in fiscal
2003. Net loss attributable to common stockholders after deducting non cash
dividends on preferred stock was $(0.07) per share compared to $(0.13) per share
for the same quarter last year.

"We believe our first quarter revenue performance begins to demonstrate the
revenue growth potential of our company," said Chairman, Elwood G. Norris. "The
Government Group made a strong contribution including:

         o        LRAD(TM) sales to the U.S. Army and U.S. Coast Guard
         o        Contract fees for pan/tilt remotely-operated LRADs for
                  integration into U.S. Navy shipboard force protection systems
         o        Outdoor emergency response applications utilizing NeoPlanar(R)
                  technology
         o        Development fees for a new aircraft carrier flight deck voice
                  communication system

We anticipate second quarter 2004 revenues will include the Business Group's
NeoPlanar order announced in December. We expect to recognize over $250,000 on
this order contributing to a significant increase in revenues over the second
quarter of fiscal 2003 as well as exceeding first quarter fiscal 2004 revenues."

Mr. Norris added, "HSS(R) shipments are growing. In the last six months we have
shipped HSS systems to 28 different customerS including Sony Business Europe and
iPort Media, Inc. We are focusing HSS sales and marketing efforts on companies
interested in our proprietary systems for Digital Signage, Trade Shows and Point
of Purchase. We continue to experience strong demand for our proprietary sound
products and technologies and we expect HSS, NeoPlanar and LRAD shipments to
continue to ramp during 2004."
