There were made tests of particulate matter (aerosol), of coagula-tion efficiency, depending on the acoustic field sound pressure and frequency. It is described experimental stand that is used to do researches and methodology of experiments performance. It is used two sound generators for acoustic field excitation: piezoe-lectric and aero-acoustic. It was determined after researches, that increasing the frequency of the acoustic field, it is increased rate of particle coagulation when particle diameter not greater than 1 μm. Effectively coagulation of particles up to 1 μm in diameter must subsonic acoustic field frequencies, as the particles over 1 μm in diameter must be lower than the frequency of ultrasonic acoustic field.
