Government and Force Protection System's Group

Company Reports Change of Auditors

SAN DIEGO, California, July 7, 2005- American Technology Corporation (NASDAQ: ATCO), a leading innovator of proprietary sound reproduction technologies and products, today announced preliminary unaudited revenues of approximately $1.2 million for the quarter ended June 30, 2005. The company also announced that it expects revenues in the fourth quarter ending September 30, 2005 to be approximately $4 million.

"Before any contribution from fourth quarter revenues, revenues for the first nine months of fiscal 2005 have already exceeded total fiscal 2004 revenues by 44 percent," said Kalani Jones, ATC's chief operating officer and president. "Our fiscal third quarter revenues are consistent with our previous guidance of uneven quarterly revenues due to the early stages of the markets and products in which we are involved."

Jones added, "We allocated substantial resources in fiscal Q3 to expand our product line and prepare our MRAD™ and HSS® H450 products for market. We are pleased with the market reception to these new products. MRAD has been successfully demonstrated to a wide range of government, military and commercial customers. Also, we have a growing backlog of H450 orders that today is in excess of $300,000 with further orders expected. We also expect other new products outlined in our June 16, 2005 release to contribute revenues in fiscal Q4." (http://www.atcsd.com/PressReleases/06_16_05.html)

The company further announced that A.J. Ballard has been promoted to senior director of ATC's government and force protection systems group. Ballard previously was director of LRAD™ and MRAD sales and marketing in the group and has been responsible for LRAD sales since early 2004.

"A.J. and his team have been instrumental in the success of LRAD; we are pleased to have him take over leadership of our government group sales efforts," commented Jones. "Ken Winter will support A.J. by continuing in his position as director of NeoPlanar®-based government and force protection product sales."

"I appreciate the opportunity to lead a great team dedicated to ramping sales of unique sound solutions to government, military and commercial force protection customers," said Ballard. "Based on LRAD's continuing success in Iraq and around the world, we are making significant progress with national and international government and military officials in landing expected larger, more frequent LRAD and MRAD orders."

The company reported that it has engaged Swenson Advisors, LLP (Swenson) as its principal independent registered public accounting firm following the resignation of BDO Seidman, LLP (BDO). In connection with BDO's audit for each of the fiscal years ended September 30, 2004 and 2003, and through the interim period from October 1, 2004 through June 29, 2005, there have been no disagreements between ATC and BDO on any matters of accounting principles or practices, financial statement disclosure or auditing scope or procedure.

Swenson is one of California's fastest growing regional accounting firms with worldwide services through INTEGRA International. Swenson's professional team provides a full range of financial solutions to expanding enterprises. Swenson will be reviewing the company's financial statements for the quarter ended June 30, 2005 and auditing the company's financial statements for the year ending September 30, 2005.

Jones also announced, "With a strong portfolio of products ready for market, we have transitioned from having a large in-house engineering staff to building our sales and marketing organization. While we continue to have a talented core research and development group, we have recently, significantly reduced our engineering resources. We anticipate this will improve our overall fiscal Q4 operating results and substantially lower our monthly operating costs going forward."

"After having allocated significant resources over the last two quarters in accelerating the completion of MRAD, H450, Sound Sentinel™, Sound Vector™ and other sound reproduction devices, we are now focused on the sales and marketing of these products," Jones concluded. "We expect results in fiscal Q4 will demonstrate that our commercial products group is on its way to contributing significant revenues to ATC, while our government and force protection systems group improves over fiscal Q3."
