August 2003

Dear Fellow Shareholders:

         I am pleased to report that the period  from  August  2002  through the
present has seen substantial growth at Sonex. During the second half of 2002 the
Company  secured  new engine  development  projects  from  branches  of the U.S.
government  and  Department  of Defense  (DoD) and/or  their prime  contractors,
resulting  in  record  revenues  for 2002 and 2003 to  date.  We  increased  our
full-time  staff  from  three to  seven,  added  two  part-time  employees,  and
continued  to have access to  high-caliber  technical  consultants.  Significant
upgrades have been made to our  engineering and design  capabilities  which will
lead to greater  efficiencies  in fabricating  and analyzing  Sonex  development
components.

         This year the Company has expanded its marketing and  commercialization
capabilities  by hiring  specialized  consultants to provide  business  advisory
services in areas such as strategic alliances, federal marketing, and government
procurement  assistance.  We also have made an effort this year to increase  the
industry exposure  worldwide of the Sonex Combustion  System (SCS)  technologies
with technical  publications  and  presentations  for the  international  engine
community.

         Along with the boost in  revenues  from the new  contracts  has come an
increase in expenditures through higher personnel costs for the expansion of our
technical staff and improvements to our test facility and computer  capabilities
to meet the demands of the  projects,  as well as the new  spending on marketing
and commercialization services. The Company has been able to meet its cash needs
through  revenue  receipts and, among other  measures,  the continued  voluntary
deferral of salaries by Company  officers,  flexible payment  arrangements  with
consultants, and the securing of short-term loans from shareholders.

         I firmly  believe that the strides  made in the past twelve  months are
laying the foundation for successful  commercialization of the SCS technologies.
We continue to pursue new  opportunities  for revenue as we perform  development
work on the current engine  projects,  and we look for positive results from our
expanded marketing efforts.

         The  accompanying  Annual  Report  on Form  10-KSB  for the year  ended
December 31, 2002 provides a comprehensive explanation of the Company's business
initiatives and finances.  The information presented is current as of March 2003
when the Form 10-KSB was filed with the SEC, and is  supplemented by the "Report
for the Second Quarter of 2003" enclosed with the proxy materials.

         I extend my gratitude  to my fellow  shareholders  for their  continued
support,  particularly to those who have lent their time,  energy, and financial
resources to Sonex,  and to our employees and  consultants  for their  continued
hard  work.  The  Company  will hold its Annual  Meeting  here in  Annapolis  on
Tuesday,  September16,  2003,  and I look  forward to seeing many of you at that
time.


                                      Sincerely,

                                      Andrew A. Pouring, D.Eng.
                                      Chief Executive Officer

                       2003 ANNUAL MEETING OF SHAREHOLDERS
                      NOTICE OF MEETING AND PROXY STATEMENT


To the Shareholders of Sonex Research, Inc.:

The  2003  Annual  Meeting  of  Shareholders   of  Sonex  Research,   Inc.  (the
"Corporation")  will be held on Tuesday,  September 16, 2003 at 10:00 a.m. local
time in the  Dorsey  Room in the  Hampton  Inn &  Suites,  located  in the ARINC
Corporate Park, 124 Womack Drive, Annapolis,  Maryland. Holders of record of the
Common Stock and Preferred  Stock of the Corporation at the close of business on
July 28, 2003 will be entitled to notice of, and to vote, as and if  applicable,
at the Annual Meeting and any adjournment thereof.

Shareholders  will act upon the following  matters and such other matters as may
properly come before the Annual Meeting or any adjournment thereof:

        PREFERRED STOCK PROPOSAL: To elect one individual to serve as a Class II
        Preferred  Stock director until the Annual  Meeting of  Shareholders  in
        2006 and until his successor is duly elected and qualified.

If you own  shares of  Common  Stock  that are  registered  in your name  (i.e.,
represented  by actual stock  certificates),  you are receiving a Proxy directly
from the Corporation.  Holders of shares of Common Stock that are held of record
in an account  with a financial  institution  such as a brokerage or bank (i.e.,
held in "street  name") are  receiving a proxy voting  instructions  form from a
proxy  processing  firm.  The  Board of  Directors  of the  Corporation  has not
presented any proposal for vote by the Common Stock holders and currently  knows
of no proposal which may be brought before the Annual Meeting. Holders of Common
Stock are nevertheless  asked to execute the Proxy or voting  instructions  form
received to enable the Proxies to vote your shares with  respect to any proposal
which may  lawfully  and  properly be brought  before the Annual  Meeting or any
adjournment thereof.

Whether or not you plan to attend the Annual  Meeting,  please  complete,  date,
sign and promptly return the enclosed Proxy or voting  instructions  form in the
accompanying  envelope to assure that your shares are  represented at the Annual
Meeting. Proxies returned by holders of Preferred Stock with no voting direction
indicated will be voted "FOR" the Preferred Stock Proposal.

You may attend the Annual  Meeting  and vote,  as and if  applicable,  in person
shares  registered  in your name either by  submitting  a completed  Proxy or by
completing a ballot at the Annual  Meeting.  If you have returned a Proxy to the
Corporation  but later decide to attend in person,  you may revoke your Proxy at
the  Annual  Meeting  and cast your  vote,  as and if  applicable,  in person by
ballot. If you own shares of Common Stock in street name and you wish to vote in
person if any proposal later is lawfully and properly  brought before the Annual
Meeting, you must mark the appropriate box on the proxy voting instructions form
and  return it to the proxy  processing  firm,  which will then send you a Legal
Proxy to allow you to vote the shares by ballot at the Annual Meeting.


                                           By Order of the Board of Directors


                                           George E. Ponticas
                                           Secretary
                                           August 28, 2003




                             PROXY SOLICITATION

This Notice of Meeting and Proxy Statement is furnished to shareholders of Sonex
Research,  Inc. (the  "Corporation")  in  connection  with the  solicitation  of
Proxies on behalf of the Board of  Directors of the  Corporation  for use at the
Annual Meeting of  Shareholders  of the  Corporation to be held on September 16,
2003 for the  purposes set forth on the cover page of this Notice of Meeting and
Proxy  Statement.  The Board of Directors  has fixed July 28, 2003 as the record
date for the  determination  of shareholders  entitled to notice of, and to vote
at, the Annual Meeting.  The cost of preparing,  assembling and mailing of proxy
materials will be borne by the Corporation.

The Corporation will supply proxy materials as requested to brokerage houses and
other  custodians,  nominees and fiduciaries for  transmission to the beneficial
owners of the  Corporation's  securities.  The  Corporation  will reimburse such
brokerage  houses  and other  custodians  for their  expenses.  The  approximate
mailing date of this Notice of Meeting and Proxy Statement is August 28, 2003.


                              CLASSES OF SECURITIES

The Corporation has two classes of voting securities:  its $.01 par value common
stock (the "Common  Stock") and its $.01 par value  convertible  preferred stock
(the  "Preferred  Stock").  Each share of Preferred  Stock is convertible at any
time at the option of the holder into Common Stock at the rate of $.35 per share
of Common Stock. The Preferred Stock has priority in liquidation over the Common
Stock, but it carries no stated dividend. Additionally, the holders of Preferred
Stock,  voting  as a  separate  class,  have the right to elect  that  number of
directors of the Corporation  which represents a majority of the total number of
directors.  The only other  matters with  respect to which  holders of Preferred
Stock are entitled to vote concern a  consolidation,  merger,  share exchange or
transfer of assets.  Each share of Preferred Stock  outstanding will be entitled
to one vote on the Preferred Stock Proposal.



The  Corporation  is presently  authorized to issue up to  48,000,000  shares of
Common Stock and 2,000,000  shares of Preferred  Stock. At the close of business
on July 28,  2003,  there  were  21,592,669  shares of Common  Stock  issued and
outstanding  held by  approximately  900  registered  holders,  with  shares for
approximately  1,700 additional  beneficial  owners being held in street name by
brokers,  dealers,  banks, and other entities, and 1,540,001 shares of Preferred
Stock issued and outstanding held by seven registered holders.


                                  VOTING

A quorum is required  in order for the  Corporation  to conduct  business at the
Annual Meeting.  The presence,  in person or by Proxy, of the majority in number
of the  outstanding  shares of Common Stock and Preferred Stock as of the record
date  constitutes  a quorum.  If a quorum of the holders of  Preferred  Stock is
attained at the Annual Meeting,  directors will be elected by a plurality of the
shares  present  and  entitled  to  vote.  Unless  otherwise   directed  by  the
shareholder,  the shares of  Preferred  Stock  represented  by executed  Proxies
returned to the Corporation will be voted "FOR" the election of directors.

If any other matters are lawfully and properly brought before the Annual Meeting
and a quorum of the  holders  of the  Preferred  Stock  and/or  Common  Stock is
attained,  the shares of Preferred  Stock and/or  Common  Stock  represented  by
executed  Proxies returned to the Corporation will be voted in the discretion of
the Proxy holders.

A Proxy may be revoked at any time before it is voted by giving  written  notice
of  revocation,  or by  delivery of a later dated  Proxy,  to the  Corporation's
Secretary  prior to the  Annual  Meeting.  A Proxy  may also be  revoked  if the
shareholder  is present at the Annual  Meeting and gives  written  notice to the
Corporation's Secretary of his revocation at such time.


                              BOARD OF DIRECTORS

The Corporation's Board of Directors is divided into two categories: (1) "Common
Stock"  directors  elected by the holders of Common  Stock;  and (2)  "Preferred
Stock"  directors  elected by the holders of  Preferred  Stock.  Pursuant to the
Corporation's  Charter, the holders of the Preferred Stock, voting as a separate
class, have the right to elect that number of directors of the Corporation which
represents a majority of the total number of directors.  These two categories of
directors  are further  divided into three  classes as nearly equal in number as
possible,  with the term of one of the three  classes of  directors  expiring at
each annual meeting of shareholders.  The members of each class of directors are
to hold office for terms of three years until their successors have been elected
and  qualified.  The  terms of Class I,  Class II and Class  III  directors  are
scheduled to expire at the annual  meetings of  shareholders to be held in 2005,
2003, and 2004, respectively.

The Corporation's By-laws state that the Board of Directors shall consist of not
fewer than three directors,  with the total number of directors to be set by the
Board by  resolution.  In July 1997 the total number of  directors  was fixed at
five,  and, from December 2001 until early in 2003 the Board  consisted of three
Preferred Stock directors and two Common Stock directors. On March 24, 2003, Mr.
John H.  Drewanz,  a Class II  Common  Stock  director  since  October  2001 and
Chairman of the  Corporation's  Board of Directors since October 2002,  resigned
from the Board.  Mr. Drewanz  informed other  directors that he had made all the
contributions  he could as a director  and  believes  the  Company is in capable
hands with its current  management and other members of the Board.  The Board of
Directors  subsequently  decided  against  filling  the  vacancy or naming a new
Chairman.  In July  2003 the  Board of  Directors  acted  to fix the  number  of
directors at four. Currently, the Board of Directors consists of three Preferred
Stock directors and one Common Stock director.

Due to the small total  number of  directors,  the Board does not have  separate
Nominating,  Compensation or Audit Committees;  however,  the functions of these
committees  have been  performed  by the Board as a whole.  The Company does not
have an Audit  Committee  charter.  The Board  believes  its  outside  directors
possess  the  necessary  independence  and skills to perform  all the  functions
normally assigned to separate Nominating, Compensation or Audit Committees.

While it is the function of the Board to recommend  potential nominees for Board
positions,  it is also the policy of the Board to consider nominees  recommended
by security holders. Such recommendations should be addressed to the Chairman of
the Board,  at the address of the  Corporation,  and should include the name and
address of the security holder  submitting the nomination and a detailed listing
of the business  experience and particular  qualifications  of the nominee.  The
Board will review the  nomination at its next meeting  following  receipt of the
nomination  and respond  accordingly  to the security  holder who  submitted the
nomination.

Based on their education and business experience,  Board members Mr. Lawrence H.
Hyde and Mr. Charles C. McGettigan,  both of whom have experience  overseeing or
assessing the performance of companies or public accountants with respect to the
preparation,   auditing  or  evaluation  of  financial  statements,   have  been
designated  as  audit  committee  "financial  experts"  with  respect  to  Audit
Committee  functions that are performed by the Board as a whole. In general,  an
audit  committee  "financial  expert" means an  individual  who possesses (i) an
understanding  of  generally  accepted   accounting   principles  and  financial
statements;  (ii)  the  ability  to  assess  the  general  application  of  such
principles  in  connection  with the  accounting  for  estimates,  accruals  and
reserves;  (iii)  experience  preparing,   auditing,   analyzing  or  evaluating
financial  statements   containing  the  breadth  and  level  of  complexity  of
accounting  issues that are generally  comparable to such issues  encountered by
the small business  issuer's  financial  statements;  (iv) an  understanding  of
internal   controls  and  procedures  for  financial   reporting;   and  (v)  an
understanding of audit committee functions.

In performing the duties typically  assigned to an audit  committee,  the entire
Board has (1) reviewed and  discussed the 2002 audited  financial  statements of
the Corporation with management;  (2) discussed with the independent accountants
of the Corporation the independent accountants' judgments about the quality, not
just the acceptability,  of the Corporation's  accounting principles,  including
the  clarity and  completeness  of the  financial  statements  and related  note
disclosures;  (3) received  written  assurance from the independent  accountants
with  respect  to  independence;  and (4)  recommended  that  the  2002  audited
financial  statements be included in the December 31, 2002 Annual Report on Form
10-KSB for filing with the Securities and Exchange Commission (SEC).






                        PRINCIPAL SECURITY SHAREHOLDERS

The  following  table sets forth as of July 28,  2003  information  relating  to
beneficial  ownership of Common Stock by directors and executive officers of the
Corporation,  individually  and as a group,  and any other  persons known by the
Corporation  to be the  beneficial  owner  of  more  than  five  percent  of the
currently issued and outstanding  Common Stock. A reporting person is considered
the  "beneficial  owner" of a security if that person has or shares the power to
vote or to direct  the  voting of such  security,  or the power to dispose or to
direct the disposition of such security.  Under this  definition,  more than one
person  may be a  beneficial  owner of  securities  as to which he has no record
ownership  interest,  and the same shares may be beneficially owned by more than
one reporting person.

Beneficial  ownership  includes  securities which the reporting person currently
owns or has the right to acquire or the obligation to dispose within sixty days,
such as through the exercise of options,  warrants,  puts and calls,  or through
the conversion of Preferred Stock. The percentage of beneficial  ownership for a
reporting person is based on the number of outstanding shares of Common Stock of
the  Corporation  plus the number of shares which the  reporting  person has the
right to acquire  within sixty days, but does not include shares which any other
reporting  person has the right to acquire.  Unless  otherwise noted, all shares
are  beneficially  owned and sole  voting  and  investment  power is held by the
persons named.

     which  shares  could be  deemed  to be  beneficially  owned by both Mr.

     positions in Proactive,  et.al.  Both individuals exercise shared voting

(2)  Represents the currently exercisable portions of ten-year options granted
     in December 1997 and December 1999 by Proactive, et.al. to Mr. Hyde to
     purchase 714,286 shares and 500,000 shares, respectively, of common stock
     presently owned by Proactive, et.al., at an exercise price of $.35 and
     $.50 per share, respectively. The December 1997 and December 1999 options
     become exercisable at the rate of 20% and 25% respectively, per year
     beginning with the date of grant. Because these agreements relate to
     shares which are already outstanding, the  exercise of such  rights will
     not result in an increase in the total number of the Company's
     outstanding  shares  for purposes of computing  the  percentage of
     beneficial  ownership  of each reporting person. Mr. McGettigan and Mr.
     Wick each has indirect beneficial ownership in 50% of the shares subject
     to these agreements.






                                STOCK OPTION PLAN

The Corporation maintains a non-qualified stock option plan adopted in 1987 (the
"Plan") which has made  available for issuance a total of 7.5 million  shares of
Common  Stock.  The  Corporation  does not have any other stock  option or other
similar equity compensatory plans. Shareholder approval was not required for the
adoption of the Plan,  nor is it required for any  amendments  to the Plan.  All
directors,  full-time  employees and consultants to the Corporation are eligible
for  participation.  Option awards are determined at the discretion of the Board
of  Directors.  Upon a change in control  of the  Corporation,  all  outstanding
options granted to employees,  officers and directors become vested with respect
to those options which have not already vested.  Options  outstanding  expire at
various  dates through June 2013. A copy of the Plan has been filed with the SEC

 (2) Includes $53,171 for 2002 and $33,232 for 2001 which has not been paid as
      of December 31, 2002.
 (3) In November 2002 Dr. Pouring was granted an option to purchase 100,000
      shares of Common Stock effective as of January 1, 2003.


In order to help conserve the  Corporation 's limited cash  resources,  however,
the Named  Executives  for several years have  voluntarily  deferred  receipt of
payment of significant portions of their authorized annual salaries upon request
by the Board of Directors.  By written  agreement  with the  Corporation,  these
individuals and other current and former employees  consented to the deferral of
payment of amounts so accumulated  until the Corporation has received  licensing
revenue of at least $2 million or at such earlier date as the Board of Directors
determines  that the  Corporation  's cash  flow is  sufficient  to  allow  such
payment.  For many years through 1998, Dr. Pouring had been deferring 40% of his
annual salary. In January 1999, the percentage  deferral was reduced to 30%. Mr.
Ponticas has been deferring 10% of his annual salary for the last several years.
The  conditions  that would  require  repayment of deferred  amounts have yet to
occur.  As of December  31,  2002,  a total of $448,923 and $125,326 in deferred
salary is owed to Dr. Pouring and Mr.  Ponticas,  respectively,  that is payable
under the conditions  described  above.  The authorized full annual salaries for
Dr. Pouring and Mr.  Ponticas for each of the past three years were $125,000 and
$96,000,  respectively.  Effective  January 1, 2003, the authorized  full annual
salary for Mr. Ponticas was increased to $120,000 while the percentage  deferral
was increased to 25%.

During  much of 2001 and  through  the third  quarter of 2002,  the  Corporation
operated under severe cash flow difficulties.  At times during 2001 and 2002 the
Corporation's  officers voluntarily and at their own discretion deferred receipt
of  payment  of  significant  portions  of their  current  wages to  reduce  the
Corporation  's monthly cash  requirements,  although some of these amounts were
repaid by the end of the year.  With the  generation  of cash flow from revenues
during the fourth quarter of 2002,  some of these amounts were repaid by the end
of the year.  Since December  2002, Mr.  Ponticas has been receiving his current
wages, while Dr. Pouring continues to defer a significant portion of his current
wages. Such wages payable to the  Corporation's  officers totaled $199,992 as of
December 31, 2002 and are payable upon demand.

In December of each of the last three years,  the  Corporation  awarded  bonuses
totaling $37,500 in 2002,  $57,500 in 2001, and $30,000 in 2000, to its officers
and employees,  including the amounts  reported above for the Named  Executives.
The bonus  awards in each year were made with the  stipulation  that  payment of
such bonuses would be deferred until the Board of Directors  determines that the
Corporation's  cash  resources  are  sufficient  to enable such  payments.  In a
private  financing in March 2002, Dr. Pouring and Mr.  Ponticas  accepted Common
Stock in payment of accrued  bonuses of $9,000  each.  As of December  31, 2002,
$22,500 and $50,000 in accrued bonuses  remained  payable to Dr. Pouring and Mr.
Ponticas, respectively.

The bonus  awards  and  option  grants in 2001 and 2002 to the Named  Executives
continued to increase to reflect the fact since 2001 these individuals have made
extraordinary sacrifices, both financially in the amount of wages that have gone
unpaid,  and personally,  to enable the Corporation to remain in operation given
its poor financial condition,  and to provide incentive for the Named Executives
to remain in the  employment of the  Corporation  under such arduous  continuing
conditions.

In order to avoid long-term financial commitments, the Corporation does not have
employment  agreements  with any of its  personnel.  The  salaries of  executive
officers  are set by the  Board  of  Directors  on an  annual  basis.  With  the
exception of the granting of stock  options,  the  Corporation  does not pay its
Named  Executives any bonuses or any type of long-term  compensation in the form
of restricted stock awards,  stock  appreciation  rights (SARs) or other form of
long-term incentive plan payments.

Common Stock.

                            COMPENSATION OF DIRECTORS

Directors of the  Corporation  do not receive fees for their  services,  but are
eligible to receive stock option grants and are reimbursed for expenses  related
to their activities as directors.  It has been the Corporation's policy to grant
outside  directors stock options every three years that have a term of ten years
and vest over a number of years.  When an individual  ceases to be a director of
the  Corporation,  he loses the rights to any shares under these  options  which
have not vested as of that date.


                             INDEPENDENT ACCOUNTANTS

In September 2003 the  Corporation's  independent  accountants since 1997, C. L.
Stewart  &  Company,   informed  the  Board  of  Directors  that  the  firm  was
discontinuing its audit practice and would not serve as independent  accountants
of the  Corporation for the year ended December 31, 2002. The Corporation had no
disagreements  with  C.  L.  Stewart  &  Company  on any  matter  of  accounting
principles or practices or financial statement disclosure.

The  Corporation's  Board of  Directors  engaged  Hausser  +  Taylor  LLP as new
independent  accountants  as of December 17, 2002.  The  Corporation  has had no
disagreements  with Hausser + Taylor LLP on any matter of accounting  principles
or  practices  or  financial  statement  disclosure.   It  is  expected  that  a
representative of Hausser + Taylor LLP will be present at the Annual Meeting and
will have an opportunity  to make a statement,  should they desire to do so, and
will be available to answer appropriate questions.

         PREFERRED STOCK PROPOSAL - ELECTION OF PREFERRED STOCK DIRECTOR

At its meeting on June 17,  2003,  the Board of  Directors  nominated  incumbent
director  Mr.  Lawrence  H. Hyde for  election  at the 2003  Annual  Meeting  of
Shareholders as a Class II Preferred  Stock  director.  The persons named in the
enclosed  Proxy have the  intention  of voting for the  election  of the nominee
unless the shareholder specifies otherwise. Although the Board of Directors does
not  contemplate  that the nominee will be unable to serve,  if such a situation
arises prior to the Annual  Meeting the persons  named in the Proxy will vote in
accordance with their best judgment.



             SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section  16(a) of the  Securities  Exchange Act of 1934  requires the  Company's
officers  and  directors,  and persons who  beneficially  own more than 10% of a
registered class of the Company's equity securities,  to file initial reports of
beneficial  ownership  and reports of changes in beneficial  ownership  with the
SEC, and to provide  copies of all such reports to the Company.  Based solely on
its  review  of  the  copies  of  such  reports   received  by  it,  or  written
representations  from reporting  persons that no reports were required for those
persons, the Company believes that all of its officers,  directors,  and greater
than 10%  shareholders  complied  with all such filing  requirements  related to
beneficial ownership of Common Stock during 2002 except as indicated below.

In August 2002 the Company was informed that certain  members of the  Proactive,
et.al. Form 13D filing group of affiliated entities and individuals,  beneficial
owners of more than 10% of the Company's  Common Stock,  had failed to report to
the Company,  and failed to file Form 4s,  covering the  following  sales of the
Company's Common Stock in 2000 and 2001:

                                                           Number
          Period of Transactions                          of shares

   June 2000 - September 2000                               78,000
   December 2000                                             6,000
   November 2001                                            11,000


In late July 2002 and August  2002  pursuant  to a Form 144 filing  with the SEC
dated July 23, 2002,  Proactive,  et.al. sold an additional 63,000 shares of the
Company's  Common  Stock for which  Form 4s were not  timely  filed.  Two of the
Company's  directors,  Mr. McGettigan and Mr. Wick, held beneficial ownership of
the  shares  sold in July  2002 by  virtue  of  their  executive  and  ownership
positions  in  Proactive,  et.al.  Form 4s covering  these sales were not timely
filed by Mr. McGettigan and Mr. Wick.

Based  solely on its review of the copies of such  reports  received  by it, the
Company  believes that Form 4s were eventually filed by Proactive,  et.al.,  Mr.
McGettigan and Mr. Wick to report all of the above-described transactions.



                                  OTHER MATTERS

The Board of  Directors  does not know of any  matters  to be  presented  at the
Annual Meeting other than those specifically set forth in this Notice of Meeting
and Proxy  Statement.  If any such matters should arise, it is intended that the
persons  named  in and  acting  under  the  enclosed  form  of  Proxy  or  their
substitutes will vote thereon in accordance with their best judgment.


                              SHAREHOLDER PROPOSALS

Any  shareholder  proposal  intended to be included in the  Corporation's  proxy
statement  and form of proxy for  presentation  at the next  annual  shareholder
meeting  must comply with  certain  rules and  regulations  with  respect to the
