On February 5, 2004, the Registrant posted the following news announcement on
its website (www.sonexresearch.com):




                        SONEX ANNOUNCES CHANGES TO BOARD



ANNAPOLIS,  MARYLAND,  February 5, 2004 - SONEX  RESEARCH,  INC.  (OTC BB: SONX)
announced  several  changes  to its  Board of  Directors  following  the  recent
resignation of three directors.

Named to the Board were Mr. Herbert J. Mitschele,  Jr., a retired business owner
residing  in New Jersey who is the  largest  individual  holder of Sonex  Common
Stock,  and Mr. George E. Ponticas,  the Company's Chief  Financial  Officer and
Secretary.  The two new  directors  have been named to serve on an interim basis
until the Company  conducts a search for  permanent  replacements.  The Board of
Directors  of the Company  now is  comprised  of three  members:  Dr.  Andrew A.
Pouring,  Chief Executive  Officer and founder of Sonex,  Mr.  Mitschele and Mr.
Ponticas.  Sonex will seek to add  individuals  who have no current  affiliation
with the Company in order to  constitute a Board with a majority of  independent
directors.

The Board members who resigned are Mr.  Lawrence H. Hyde, a director since 1986,
and Mr. Charles C.  McGettigan and Myron A. "Mike" Wick,  III,  directors  since
1992.  Mr.  Hyde,  who  resigned  this week,  is a retired  automotive  industry
executive  and a private  investor  who  informed  the Company  that he plans to
devote more time to international  business  interests.  Mr.  McGettigan and Mr.
Wick, who resigned last week,  indicated  that other  business  responsibilities
preclude them from devoting further time to Sonex.  Both are affiliated with the
Proactive et.al. investment group of affiliated entities and individuals,  which
group is the largest  beneficial  owner of the Company's Common Stock and holder
of approximately 94% of the Company's convertible Preferred Stock.

The Preferred Stockholders,  voting as a separate class, have the right to elect
that number of directors of the Company which represents a majority of the total
number of directors. As each of the directors who resigned was a Preferred Stock
director,  both Mr.  Mitschele and Mr. Ponticas were designated  Preferred Stock
directors, while Dr. Pouring is a Common Stock director.

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 in response to forthcoming  increases in
national vehicle fuel mileage standards.  Additionally,  independent third-party
testing has confirmed the potential of the SCS application  for  direct-injected
diesel  engines to 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).
