AMERICAN TECHNOLOGY ANNOUNCES

FISCAL Q3 2008 FINANCIAL RESULTS

Fiscal Q3 2008 Revenues Up 28% Over Same Period Last Year

SAN DIEGO, CA, August 4, 2008 – American Technology Corporation (ATC) (NASDAQ: ATCO), a leading provider of directed sound products and technologies, today announced revenues of $2.7 million for its fiscal third quarter ended June 30, 2008, up 28% from $2.2 million for the same period last year.

“Sales of all our directed sound product lines grew in fiscal Q3, with the largest growth coming from our new LRAD-X^™ product series,” remarked Tom Brown, president and chief executive officer of American Technology Corporation. “Since the introduction and initial deliveries of our proprietary LRAD-X systems in late March, we have experienced growing domestic and international acceptance and increasing market demand that is continuing in fiscal Q4.”

“With the fulfillment of a previously announced $1.1 million LRAD RX^™ order and the expected deliveries of the recently announced Marine Expeditionary Security Force LRAD 500X^™ order and other pending orders, we’re forecasting a strong Q4,” added Brown.

Gross profit for the third fiscal quarter was $1.0 million, or 38% of revenues, compared to a gross profit of $1.0 million, or 46% of revenues, for the quarter ended June 30, 2007. The gross profit percentage on opening LRAD-X shipments was lower than prior year LRAD^® product sales due to initial start-up production and freight costs. The Company expects LRAD-X margins to improve through increased production volume.

Operating expenses for fiscal Q3 2008 were $2.6 million, an increase of $354,000 from the quarter ended June 30, 2007. The increase resulted primarily from higher research and development expenses associated with finalizing the LRAD-X product series.

Net loss for the three months ended June 30, 2008 was $1.5 million or $(0.05) per share, compared to a net loss of $1.1 million or $(0.04) per share for the same period last year. The increased loss was attributable primarily to final development costs associated with the Company’s LRAD 1000X^™, LRAD 500X and LRAD RX.

For the nine months ended June 30, 2008, the Company reported revenues of $7.3 million, a 12% decrease from $8.3 million for the same period a year ago. For the first nine months of fiscal 2008, gross profit was $2.9 million, or 40% of revenues, compared to $4.1 million, or 49% of revenues, for the same period last year. Revenues and margins were lower due to the Company’s transition to the LRAD-X series and product sales mix.

Operating expenses increased to $8.3 million for the nine months ended June 30, 2008 from $7.0 million for the same period a year ago due mainly to an increase in research and development expenses associated with the development and productization of the Company’s new LRAD-X series including its proprietary pan-and-tilt drive and increased non-cash share-based

compensation. The net loss for the nine months ended June 30, 2008 was $5.4 million or $(0.18) per share, compared to a net loss of $2.7 million or $(0.09) per share for the same period last year. The increased loss was attributable to lower sales, increased research and development expenses and increased share-based compensation expense compared to the same period in the prior year.

“Our significant investment earlier this year, enhancing and upgrading our LRAD technology and products, is quickly being repaid through growing order demand for our proprietary LRAD 1000X, LRAD 500X and LRAD RX systems from diverse military and commercial security interests,” commented Brown. “We expect further LRAD-X orders and first shipments of our handheld LRAD 100X^™ this quarter will contribute to higher revenues for fiscal year 2008 over 2007.”

Brown concluded, “We will be discussing the fiscal Q3 results and other business developments on our August 5^th conference call.”
