Exhibit 99.1

                         AMERICAN TECHNOLOGY CORPORATION
                      REPORTS FISCAL THIRD QUARTER RESULTS


SAN DIEGO, California, August 9, 2005 - American Technology Corporation (NASDAQ:
ATCO) an innovator of proprietary sound reproduction technologies, today
reported results for its third fiscal quarter of 2005 ended June 30, 2005.
Revenues for the quarter were $1.39 million compared to $2.11 million for the
third quarter of fiscal 2004, a decrease of 34 percent. The company's mix of
business in the third quarter of 2005 was approximately 88% government and force
protection systems group and 12% commercial products group, compared to 87% and
13% for the three month period ended June 30, 2004. The decrease in revenues in
the third quarter resulted primarily from reduced government sales of LRAD(TM)
products compared to the same period of 2004. The company's government sales
consist of large sales to a limited number of customers and the timing of
deliveries can cause quarterly results to fluctuate widely.


The company reported a gross profit of $0.40 million for the third quarter
compared to $1.10 million for the same quarter in fiscal 2004. The company also
reported a loss from operations of $3.75 million for the quarter, compared to a
loss from operations of $1.40 million for the same period in fiscal 2004. The
third quarter's research and development expenses reflected high levels of
prototype costs, temporary staffing and other startup costs associated with
MRAD(TM) and HSS(R) H450 products. Other operating costs increased as the
company marketed more products and incurred increased public company compliance
costs.


Net loss available to common stockholders for the third quarter of 2005 was
$(0.17) per basic and diluted share, compared to $(0.09) per basic and diluted
share for the same period last year.


Revenues for the first nine months of fiscal 2005 were $8.62 million compared to
$4.38 million for the first nine months of fiscal 2004, an increase of 97
percent. For the nine month period ended June 30, 2005, the company's mix of
business was approximately 95% government and force protection systems group and
5% commercial products group, compared to 82% and 18% for first nine months of
fiscal 2004.


The company reported a gross profit of $4.65 million for the first nine months
of fiscal 2005 compared to $2.02 million for the same period in fiscal 2004. The
company also reported a loss from operations of $6.50 million for the first nine
months, compared to a loss from operations of $3.73 million for the same period
in fiscal 2004. The increased operating loss was due to temporary increases in
research and development, and increases in selling, general and administrative
expenses.


For the first six months of fiscal 2005, net loss available to common
stockholders including non-cash deemed dividends was $(0.41) per basic and
diluted share compared to $(0.24) per basic and diluted share for the same
period last year.


MANAGEMENT COMMENTARY

"We are very excited by both customers' and market reaction to our new HSS H450
and MRAD products reflected in new orders, backlog, increasing product trials
and demonstrations," said Kalani Jones, president and chief operations officer
of American Technology Corporation. "We now have an impressive line of eight
products, protected by over 320 U.S. and foreign patents and pending patent
applications, that provide a wide range of directional sound solutions for
current and prospective customers. We expect a significant reduction in research
and development expenses in the fourth quarter as we have substantially reduced
the number of employees and temporary contractors and have completed related
prototyping and startup costs."


"We remain on track for a substantial increase in fiscal 2005 revenues over
fiscal 2004, having recorded over $8.62 million in products and services in the
first nine months of the fiscal year. While our quarterly revenues will
fluctuate due to the early stages of the markets and products in which we are
involved and the timing of product deliveries, we expect a major improvement in
our operating and financial performance as we focus on sales and maintain a lean
organization."


Jones concluded, "We expect to record revenues this quarter from our growing
backlog of orders for our new HSS H450, our recently announced SoundVector(TM)
product license, and from MRAD, LRAD and NeoPlanar(R)-based products sales. We
continue to expect approximately $4 million in revenues in fiscal Q4 2005, with
significant contributions from both the government and force protection systems
group and the commercial products group."
