Results of calculations from a linear source with variable noise characteristics along the length are discussing. On one hand, the issues of calculations from linear sources are well studied and the results are presented in many works. On the other hand, problems of calculations from linear sources with variable characteristics along the length have not been studied enough, and there are no results of calculations from linear sources with variable characteristics along the length. This article deals with the case when the radiated sound energy along the length of a linear source is not constant but varies along its length. Results of calculations from a linear source with variable noise characteristics along the length are given. Various factors that affect to calculation results are discussed. The results have of practical interest. For example, this concerns the calculation of noise from a gas pipeline after a gas control point (GCP). The noise from it along the length of the pipeline decreases. The results of calculations allow to make the necessary decisions to create a low-noise object and select the necessary measures for its sound attenuation.
