The purpose of the study is the changes of audile pressure amplitude of the second harmonious in the horn at excitement in horn neck of the finite size wave as well as a perseverance of the coordinate of the horn’s main section at that the amplitude reaches allure maximum value. The examining verbalizations allowing resolving the laws of increase and decrease of the second harmonious at excitation of the fixed amplitude wave on the way-horn are acquired. The distance where the second harmonious propagating near the air-horn reaches allure maximum is determined. Comparative reasoning for air-horns of different shapes is acted. The frequency of the audile signal in such a spokesperson is 20 Hz. The frequency of the second harmonious of acoustic signals 40 Hz. Method of extinguishing of second harmonious is developed.
