Gas turbine unit (GTU) is the most intensive source of constant noise during normal operation. The noise of the gas turbine unit is emitted from the compressor intake, from the installation shell and from the chimney mouth of the gas turbine unit. Mathematical models for GTU of various capacities are compiled. It is shown that the determining role plays the noise from combustion. That noise is radiated from the chimney outside. Considered various factors affecting noise emission. Obtained empirical formulas for calculating the noise level at various distances depending on the power of the gas turbine. For the first time indicated the importance of taking into account regional climate factors to determine the required noise reduction from GTU. This is especially important to consider when determining the required reduction at high frequencies. The set of factors considered in this paper allows us to determine the required reduction from the gas turbine. Indicated possible measures to reduce noise from gas turbine unit and bring it to sanitary standards.
