(Exact name of registrant as specified in Charter) Maryland 0-14465 52-1188993 (State or other (Commision file (IRS employer jurisdiction of number) identification no.) incorporation) 23 Hudson Street, Annapolis, MD 21401 (Address of principal executive offices) (410) 266-5556 (Registrant's telephone number, including area code) N/A (Former name or former address, if changed since last report) ITEM 5. - OTHER EVENTS AND REGULATION FD DISCLOSURE On February 5, 2004, the Registrant posted the following news announcement on its website (www.sonexresearch.com): SONEX ANNOUNCES CHANGES TO BOARD ANNAPOLIS, MARYLAND, February 5, 2004 - SONEX RESEARCH, INC. (OTC BB: SONX) announced several changes to its Board of Directors following the recent resignation of three directors. Named to the Board were Mr. Herbert J. Mitschele, Jr., a retired business owner residing in New Jersey who is the largest individual holder of Sonex Common Stock, and Mr. George E. Ponticas, the Company's Chief Financial Officer and Secretary. The two new directors have been named to serve on an interim basis until the Company conducts a search for permanent replacements. The Board of Directors of the Company now is comprised of three members: Dr. Andrew A. Pouring, Chief Executive Officer and founder of Sonex, Mr. Mitschele and Mr. Ponticas. Sonex will seek to add individuals who have no current affiliation with the Company in order to constitute a Board with a majority of independent directors. The Board members who resigned are Mr. Lawrence H. Hyde, a director since 1986, and Mr. Charles C. McGettigan and Myron A. "Mike" Wick, III, directors since 1992. Mr. Hyde, who resigned this week, is a retired automotive industry executive and a private investor who informed the Company that he plans to devote more time to international business interests. Mr. McGettigan and Mr. Wick, who resigned last week, indicated that other business responsibilities preclude them from devoting further time to Sonex. Both are affiliated with the Proactive et.al. investment group of affiliated entities and individuals, which group is the largest beneficial owner of the Company's Common Stock and holder of approximately 94% of the Company's convertible Preferred Stock. The Preferred Stockholders, voting as a separate class, have the right to elect that number of directors of the Company which represents a majority of the total number of directors. As each of the directors who resigned was a Preferred Stock director, both Mr. Mitschele and Mr. Ponticas were designated Preferred Stock directors, while Dr. Pouring is a Common Stock director.

Tel: 410-266-5556; email: sonex@erols.com; website www.sonexresearch.com About Sonex Sonex Research, Inc., a leader in the field of combustion technology, is developing its patented Sonex Combustion System (SCS) piston-based technology for in-cylinder control of ignition and combustion, designed to increase fuel mileage and reduce emissions of internal combustion engines. Sonex plans to complete development, commercialize and market its Sonex Controlled Auto Ignition (SCAI) combustion process to the automotive industry to improve fuel efficiency of gasoline powered vehicles in response to forthcoming increases in national vehicle fuel mileage standards. Additionally, independent third-party testing has confirmed the potential of the SCS application for direct-injected diesel engines to reduce harmful soot in-cylinder without increasing fuel consumption. Other SCS designs are being used to convert gasoline engines of various sizes to operate on safer, diesel-type "heavy fuels" for use in military and commercial applications requiring light weight and safe handling and storage of fuel, such as in UAVs (unmanned aerial vehicles).
