The invention discloses a method for eliminating haze in an airport by means of sound waves. The method for eliminating the haze in the airport by means of the sound waves is characterized in that a haze eliminating device used when the sound waves are used for eliminating the haze and is mainly composed of a signal generator, a power amplifier, a loudspeaker box and a power supply, and the haze eliminating device is installed at a set position of the airport. When the haze appears in the airport, the power supply is powered on, the signal generator generates an electric signal at the frequency between 15 GHz and 0.5 GHz, the electric signal is amplified by the power amplifier, the electric signal output by the power amplifier 2 is converted into a sound signal, vapor in the air vibrates along with the sound waves, small water drops are converged into big water drops, then rainwater is formed, dust particulate matter in the air is infused in the rainwater and falls to the ground along with the rainwater, and the haze is eliminated rapidly. By the adoption of the method for eliminating the haze in the airport by means of the sound waves, the problem that normal taking off and landing of a plane are influenced by the haze in the airport is well solved; the haze can be eliminated rapidly, normal taking off and landing of the plane are guaranteed, great convenience is brought to travelers when the travelers go out, and meanwhile the great economic loss caused by haze is reduced.
