ABSTRACT:
The invention relates to a process for the controlled disposal of an aerosol cloud by means of directed sound waves of high intensity in the audible frequency range. According to the invention, sound waves are emitted by an aircraft (8, 10) operating close to the periphery of the cloud (4). The frequency spectrum of the wave consists of a basic frequency and a superposing frequency of twice the basic frequency valve and phase-shifted in relation to the basic frequency at substantially 90.degree., so as to cause the particles to coagulate and to migrate towards the sound source, and to be collected at the aircraft.
