ITEM 8.01 - OTHER EVENTS

On August 22, 2006, the  Registrant  posted the following  announcement  on its
website (www.sonexresearch.com):


INVESTORS REFILE FEDERAL LAWSUIT PREVIOUSLY DISMISSED


ANNAPOLIS,  MARYLAND,  August 22,  2006 - SONEX  RESEARCH,  INC.  (OTC SONX) has
learned that on August 18, 2006 a group of  Pennsylvania  investors  amended and
refiled their federal  lawsuit which had been dismissed in July 2006 by the U.S.
District Court for the Eastern  District of Pennsylvania for failure to meet the
legal standard for bringing a valid complaint under applicable federal and state
securities laws. Sonex management  continues to believe that, aside from failing
to meet the legal  requirements,  many  aspects  of the  claims  in the  Amended
Complaint are without  merit and contain  factual  inaccuracies.  Sonex plans to
timely respond to the Complaint and defend itself accordingly.

The original  Complaint was filed in February 2005 by Bruce W. Majer of Plymouth
Meeting, PA, Allen W. Fortna of Whitehall,  PA, and the Hermitage Partnership of
Philadelphia, PA (together,  referred to as the "Investors").  The Complaint was
an action for federal and state securities fraud,  common law fraud, and related
claims by the  Investors  who believe they were  induced to purchase  securities
based on a series of alleged misstatements and omissions,  and was filed against
Sonex, its former  President,  CEO and director Roger D. Posey,  former director
Jim Z.I. Williams,  current CFO, Secretary and director George E. Ponticas,  and
Dr. Andrew A. Pouring,  current Sonex Chairman of the Board,  CEO and President.
The Investors sought the return of $175,000 in equity  investments made in Sonex
during 2004. Sonex notes that Mr. Majer is a former colleague of Mr. Posey.

In March 2005 Sonex  filed its Motion to Dismiss  the  Complaint  for failure to
state a  cognizable  claim as a matter of law,  which  motion was granted by the
Court on July 19, 2006. The Plaintiffs had 30 days to file an Amended Complaint.

The  Amended  Complaint  restates  the  claims of the  original  lawsuit,  cites
additional examples of alleged misrepresentations, and makes several allegations
concerning  the  involvement  of former Sonex  consultant  James A. Rose, II, of
Arnold,  Maryland,  president  of  Global  Equity  Consultants,  Inc.  ("GECI"),
contending  that Rose had  authority  to act on behalf of Sonex and his  alleged
misrepresentations,  in part,  induced the  Plaintiffs  to invest.  Despite such
allegations, the Amended Complaint does not name Rose or GECI as defendants.

In September 2005 GECI filed an action against Sonex for alleged non-delivery of
stock  pursuant to a consulting  agreement.  Sonex opposed the claim,  asserting
that the  consulting  agreement  was  procured by negligent  and/or  intentional
concealment by Mr. Rose of the fact that GECI had transferred  300,000 shares of
Sonex stock to Jim Z.I. Williams, one of three members of the Board of Directors
who was to vote to approve  the  consulting  agreement.  In April  2006,  GECI's
Motion for Summary Judgment against the Company was denied.

In July 2006 GECI filed another  lawsuit,  a stockholder  derivative  complaint,
against Dr. Pouring and Mr. Ponticas alleging violations of Maryland Corporation
Law with  respect  to  interested  director  transactions.  This  latest  action
challenges the grant by Sonex in early 2005 of security interests in its patents
to its officers, directors and other creditors to secure payment of compensation
being  deferred  on an ongoing  and future  basis as well as new loans and other
financial  obligations.  The stockholder  derivative  complaint alleges that the
security interest was "procured by negligent and/or  intentional  concealment of
material facts" and seeks  rescission of the  transaction.  GECI claims that the
transaction  "is unfair and  unreasonable"  to Sonex.  Three local  shareholders
previously  filed a lawsuit in April 2005  challenging the grant of the security
interests,  but after  court-ordered  mediation  in July  2005,  the  matter was
settled and voluntarily dismissed by those plaintiffs in March 2006.

Dr. Pouring and Mr.  Ponticas  believe that the  allegations in the  stockholder
derivative  complaint  are without merit and that the filing of the lawsuit does
not serve the best  interests  of Sonex  stockholders  as implied by GECI in the
Complaint.  They believe the grant of the security interests,  taken to keep the
Company  in  operation,   meets  the  legal  standard  for  interested  director
transactions  that requires  such  transactions  to be fair and  reasonable to a
corporation.

While both of the actions by GECI  continue  in  litigation,  the  parties  have
engaged in settlement discussions.

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.




RISK FACTORS

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  Annual
Reports on Form 10-KSB for the years ended  December 31, 2004 and 2005 primarily
because it lacks the  financial  resources to engage an  independent  registered
public accounting firm to conduct an audit of the related  financial  statements
and because it lacks the  staffing to prepare the Forms 10-KSB due in large part
to the amount of time management has devoted and the amount of funds the Company
has spent in responding  to  litigation.  For the same reasons,  the Company has
been unable to file its Quarterly  Reports on Form 10-QSB for 2005 and 2006. 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. In  addition,
there can be no assurance  that a public market for the  Company's  Common Stock
will continue to exist.
