ITEM 8.01 - OTHER EVENTS

On September 29, 2005, the Registrant  posted the following  announcement on its
website (www.sonexresearch.com):


                     CONSULTANT FILES LAWSUIT AGAINST SONEX

ANNAPOLIS,  MARYLAND,  September 29, 2005 - SONEX  RESEARCH,  INC. (OTC SONX), a
leader in the field of combustion technology,  announced that it was served last
week with a lawsuit  filed by  Global  Equity  Consultants,  Inc.  ("GECI")  for
alleged  non-delivery  of shares of Sonex Common  Stock for  services  allegedly
rendered to Sonex under a Consulting Agreement dated April 30, 2004.

GECI of Arnold, Maryland, filed a Complaint in the Circuit Court in Anne Arundel
County,  Maryland,  demanding delivery of 1 million shares of Sonex Common Stock
without restrictions pursuant to the Consulting Agreement with Sonex executed by
James A. Rose, II, President of GECI, for financial  advisory and other services
following the hiring of former Sonex  President  Roger D. Posey.  Alternatively,
GECI seeks $1 million in damages.

Sonex  states that GECI was  compensated  with  delivery of 1 million  shares of
unrestricted  Sonex  Common  Stock,  and there is a dispute over whether GECI is
entitled to any additional compensation under the Consulting Agreement.
Sonex plans to timely respond to the Complaint and defend itself accordingly.

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.  Additionally,  independent third-party
testing has confirmed the potential of the SCS application  for  direct-injected
diesel  engines  to  significantly   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).


CAUTION REGARDING FORWARD-LOOKING STATEMENTS

"Forward-looking"  statements  contained in this report, as well as all publicly
disseminated  material about the Company, are made pursuant to the "safe harbor"
provisions of the Private  Securities  Litigation Act. Such statements are based
on current  expectations,  estimates,  projections and assumptions by management
with respect to matters such as commercial acceptance of the SCS technology, the
impact of  competition,  and the  Company's  financial  condition  or results of
operations.  Readers are cautioned  that such  statements  are not guarantees of
future  performance and involve risks and uncertainties  that could cause actual
results to differ  materially from those  expressed in any such  forward-looking
statements.

Additional  information  regarding  the risks  faced by Sonex is provided in the
Company's  periodic  filings with the Securities and Exchange  Commission  (SEC)
under the heading "Risk  Factors".  Such filings are available upon request from
the Company or online in the SEC's EDGAR database at  www.sec.gov.  The Company,
however,  is delinquent in its filings with the SEC. It has not filed its Annual
Report on Form 10-KSB for the year ended  December 31, 2004 because it lacks the
financial resources to engage its independent accountants to conduct an audit of
the December 31, 2004 financial statements and because its limited staff has not
had time to prepare the Form 10-KSB  itself.  For the same reasons,  the Company
has been unable to file its Quarterly  Reports on Form 10-QSB for March 31, 2005
and June 30, 2005. The Company is unable to predict when it will be able to make
these  filings and there can be no  assurance  that the filings  will be made at
all.



SIGNATURES

Pursuant  to the  requirements  of the  Securities  Exchange  Act of  1934,  the
