The purpose of the study is the changes of acoustic pressure amplitude of the second harmonic in the horn at excitation in horn throat of the finite amplitude wave as well as a determination of the coordinate of the horn’s axial section at which the amplitude reaches its maximum value. The analytical expressions allowing analyzing the laws of increase and decrease of the second harmonic at excitation of the finite amplitude wave in the air-horn are obtained. The distance where the second harmonic propagating along the air-horn reaches its maximum is determined. Comparative analysis for air-horns of different shapes is performed. The frequency of the acoustic signal in such a mouthpiece is 20 Hz. The frequency of the second harmonic of acoustic signals 40 Hz. Method of extinguishing of second harmonic is developed.
