Studies conducted to assess the noise characteristics of cotton machine-tractor aggregates (MTA) and their main sources have shown that the primary noise sources of cotton MTAs are the power unit, transmission of the base tractors, active working bodies, various mechanisms and structural elements of mounted or trailed machines, as well as the technological processes occurring in the machines. The article presents a noise-protection acoustics model for cotton-harvesting machine-tractor aggregates (MTA).
