SECURITIES AND EXCHANGE COMMISSION Washington, D.C. 20549 FORM 8-K CURRENT REPORT Pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 Date of Report (Date of earliest event reported): May 28, 2002 SONEX RESEARCH, INC. (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 On May 28, 2002, Sonex Research, Inc. (the "Company") posted the following notice to shareholders on its website (www.sonexresearch.com): COMPANY RESPONDS TO DECLINE IN STOCK PRICE; CEO EXPRESSES CONFIDENCE IN PROSPECTS Annapolis, Maryland May 28, 2002 To the Shareholders of SONEX RESEARCH, INC. (OTC BB: SONX): In light of the sudden decline in our stock price at the end of last week, I wanted to inform you that there have been no recent adverse developments at Sonex and that management remains confident in the Company's prospects. In fact, both our CFO, George E. Ponticas, and I acquired more Sonex shares in the Company's most recent private financing at the end of March 2002, and we are continuing to defer payment of significant portions of our current wages to reduce the Company's cash flow requirements. The Company has high expectations of being awarded a significant contract in the near future for SCS heavy fuel engine development. Feedback to date has been positive on our proposal for conversion of an automotive gasoline engine to operate on diesel-type heavy fuel for application in a large UAV (unmanned aerial vehicle) for the military. We also believe the prospects are good for a potential subcontract award to Sonex for an effort relating to a vehicular diesel engine application being developed in conjunction with a commercial partner. For its part in this proposed program, Sonex would work on a state-of-the-art, multi-cylinder, automotive diesel engine to apply our SCRI combustion process. A successful result from this proposed government funded program would provide SCRI data on a multi-cylinder diesel engine for presentation to any engine manufacturer without being subject to the confidentiality restrictions that exist in our commercial development programs. This month the Company engaged the services of a professional investor relations and financial communications firm to develop, implement and maintain an ongoing program to increase the investment community's awareness of Sonex activities. Shortly, we will provide details on this new relationship, including contact information and a website address. I remain very optimistic about the commercial prospects for the Sonex combustion technologies. The Company will continue to seek the resources and commercial partners necessary to complete development work. I wish to thank our shareholders for your continued support and patience. Very truly yours, Andrew A. Pouring, D.Eng. Chief Executive Officer ********************** Sonex Research, Inc., a leader in the field of combustion technology, has its SCS technology protected by numerous patents issued and pending worldwide.

Other SCS designs are being used to convert small gasoline engines to heavy fuel use for military and commercial applications.
