The issue shows theoretical and practical approach to the massive single-layer partition’s design on the base of lumped model’s method, provided by Zakharov A.V. The expediency of using the “Mass Law’s” formula in case of the normal noise wave’s incidence on the sound isolating partition, due to the adherence of continuity conditions of sound waves transmission at the interface of two media, is approved. The common simplified equations for the massive partition’s sound insulation for the engineering method, which is based on lumped (discrete) models, are derived. The execution sequence of one-layer partition’s engineering insulation design is given and the frequency response graph for the concrete one-layer partition based on this design is also represented. The comparison results of the medial three octave deviations of the sound isolation figures from the experimental data between Russian normative document method and the proposed engineering method for the different construction materials are represented.
