  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.
