The invention discloses a sound insulation material configuration method for reducing unit operation noise, and belongs to the technical field of air conditioner noise reduction. The sound insulation board comprises a sound insulation material; the sound insulation material comprises a white sound insulation material, a black sound insulation material, new front panel sound insulation cotton and old front panel sound insulation cotton; after the sound insulation materials are matched differently, the sound insulation materials are installed at different positions of the compressor respectively, then noise of a unit is tested, and multiple sets of test results corresponding to matching of the different sound insulation materials and different installation positions are obtained; according to multiple groups of different test results, the sound insulation material with the minimum noise decibel is selected for cooperation, and the installation position serves as the best choice for noise reduction of the unit.
