ITEM 8.01 - OTHER EVENTS

On February 12, 2007, the Registrant  Sonex Research,  Inc.  ("Sonex")  issued a
news release  announcing  that it intends to respond to a notice from the SEC by
entering into an offer of settlement  to revoke the  registration  of its Common
Stock.  The  Registrant  also posted the following  announcement  regarding this
subject to its website www.sonexresearch.com:


SONEX INTENDS TO RESPOND TO SEC NOTICE BY ENTERING INTO OFFER
OF SETTLEMENT WITH THE SEC TO REVOKE STOCK REGISTRATION


ANNAPOLIS,  MARYLAND,  February 12, 2007 - SONEX RESEARCH,  INC. (OTC:  SONX), a
leader in the field of combustion  technology,  announced today that it recently
received a letter from the Securities and Exchange  Commission  ("SEC")  stating
that  because  Sonex  is  delinquent  in  its  annual  and  quarterly  reporting
requirements  under  Section 13(a) of the  Securities  Exchange Act of 1934 (the
"Exchange  Act"),  the Company may be subject,  without  further  notice,  to an
administrative  proceeding under Section 12(j) of the Exchange Act to revoke its
registration  under the  Exchange  Act if all  required  reports  were not filed
within 15 days of the date of the letter.

Sonex is unable to file all required  reports within the prescribed time period.
The Company has  determined  that the most prudent course of action is to submit
an  Offer  of  Settlement  (the  "Offer")  to  the  SEC in  anticipation  of the
proceedings  that may be instituted  against Sonex by the SEC. Sonex has been in
contact  with the SEC  (through  counsel) and intends to submit the Offer to the
SEC within the next few days and,  shortly  thereafter,  Sonex  expects to enter
into a Consent  Order with the SEC. The Consent  Order is expected to state that
Sonex has failed to comply with  Exchange Act Section  13(a) and Rules 13a-1 and
13a-13 thereunder while its Common Stock was registered with the Commission, and
to order that pursuant to Section 12(j) of the Exchange Act, registration of the
Common Stock of Sonex  registered  pursuant to Section 12 of the Exchange Act be
revoked.  Additionally,  upon the final order signed by the SEC,  Sonex's common
stock  will no  longer  be  allowed  to trade  over the  counter  (the  stock is
currently quoted on the Pink Sheets  Electronic  Quotation  Service),  which may
adversely affect the value and liquidity of the stock.

In making the decision to enter into the Offer,  management  considered a number
of factors and obtained  advice of legal counsel.  Management  believes that had
Sonex  failed to respond to the notice  from the SEC rather  than  proposing  to
submit an Offer of Settlement,  the SEC's  Division of Enforcement  likely would
have issued an Order Instituting Proceedings before an Administrative Law Judge,
resulting in a default revocation of registration.

Sonex has not filed an Annual  Report on Form 10-KSB for any year  subsequent to
the year ending December 31, 2003, nor quarterly  reports on Form 10-QSB for any
period  subsequent  to the quarter  ending  September  30,  2004.  Sonex  became
delinquent  in its  filings  with the SEC  primarily  because of the lack of the
financial  resources to engage an independent  registered public accounting firm
to conduct audits of the related  financial  statements and the lack of staffing
to  prepare  the  periodic  reports,  due in large  part to the  amount  of time
management  has devoted and the amount of funds Sonex has spent in responding to
litigation.  Sonex has continued to file with the SEC, however,  Current Reports
on Form 8-K to disclose all  material  events.  The 8-K filings,  as well as the
past Forms 10-KSB and 10-QSB,  are  available  upon request from Sonex or on the
SEC's website at www.sec.gov.  Additionally, Sonex intends to continue to report
on  all  material  events  by  posting  such   information  on  its  website  at
www.sonexresearch.com.

Once the  Company's  registration  is  revoked  and  there is no longer a public
market for its Common Stock,  stockholders  will be prohibited from transferring
or selling  their shares  except in exempt  transactions  that are in compliance
with the United  States and  applicable  state  securities  laws.  For  example,
shareholders  may be  able  to  sell or  transfer  their  shares  as long as the
shareholders   consult  with  their  own  legal  counsel  and  comply  with  the
requirements of Rule 144 and other applicable  sections of the Securities Act of
1933. Further, the Company will only be able to raise additional capital through
the  issuance  of stock or debt in private  offerings  that are exempt  from the
registration requirements of the Securities Act of 1933.

Should the  Company be in a position in the future to have its  securities  once
again  registered,  it can do so by filing the appropriate  form of registration
statement with the SEC. While there is  considerable  expense  associated with a
registration  statement,  Sonex understands that it would not also have to incur
the costs of filing all previously delinquent reports.

Dr. Andrew A. Pouring, Sonex Chairman of the Board, CEO and President, said "The
consent to revocation of SEC  registration is not expected to have any immediate
adverse effect on the operations of the Company.  We look forward to building on
increased  commercial  interest in the Sonex  Combustion  System (SCS) for heavy
fuel engines (HFEs)."

In November 2006 (as previously  disclosed on the Form 8-K filed with the SEC on
November 7, 2006),  Sonex licensed a part of the SCS HFETM technology to Insitu,
Inc. (Bingen, WA, www.insitu.com),  a pioneer developer of long-range, unmanned,
autonomous  aircraft.  Insitu  is best  known for its long  endurance,  low cost
unmanned  aerial  systems  (UAS)  such as the  ScanEagle(R)  UAS,  developed  in
partnership  with Boeing [NYSE:  BA].  ScanEagle is used to provide services for
the US Marine Corps,  US Navy,  and  Australian  Army,  and has logged more than
30,000 hours of flight time since being deployed in 2004. In January 2007 Insitu
announced that it set an endurance  flight mark for its ScanEagle by running its
engine  modified  with  licensed  HFE  technology  from Sonex,  along with other
enhancements  developed by Insitu engineers,  on JP-5 heavy fuel. Insitu expects
to sell  ScanEagles  equipped with engines  incorporating  SCS HFETM  technology
later this year.  Sonex  continues  to provide  services  to Insitu for  further
development of licensed SCS HFETM  technology  under a  Collaboration  Agreement
also signed in November 2006.

Dr.  Pouring added that as word spreads of the Insitu license and successful HFE
flight,  Sonex is fielding  numerous  inquiries for its HFE conversion  process.
"Sonex expects to generate new funded projects for the continued development and
commercial  application  of the SCS HFETM  technology.  Our challenge will be to
expand the Company's capabilities,  which may require additional funding. We are
assessing  the  future  needs  of the  Company  and  will  work  to  develop  an
appropriate  strategy  for  moving  forward,  including  how  best  to  maximize
shareholder  value.  Sonex seeks to attract  qualified,  capable  assistance  to
pursue  commercialization  not only of the SCS HFETM  technology but also of its
piston-based  technology  for larger  engines.  It is  possible,  however,  that
revocation  of our SEC  registration  may make  raising  capital and  attracting
qualified people more difficult."

"Management  will  continue  to  work  hard  towards  the  best  result  for our
shareholders" said Dr. Pouring.  "I believe the commercial  potential of the SCS
technology  will permit  shareholders  to realize  significant  value from their
holdings,  whether  through a strategic  corporate  transaction  of some form or
through future public trading of our stock."

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).
