In work the design procedure of spatial factors of attenuation of sound waves of the zero order extending in metal pipes, filled with a liquid is offered. The analysis of processes dissipation of the acoustic energy in pipelines taking into account absorption of a sound both in liquid volume, and in an acoustic interface near to a rough surface of a pipe is carried out. Influence of excitation of standing waves in a pipe on sound attenuation is analyzed.
Key words: sound waves, attenuation, the pipeline, dissipation acoustic energy.
