| Title of the article | Noise protection characteristics of a partition on a double-spaced metal frame with different types of facing layers |
| Abstract. | Problem statement. The soundproofing performance of lightweight frame-and-sheathing structures can be as effective as that of structures made of homogeneous materials. However, the soundproofing performance of frame structures, unlike that of homogeneous structures, significantly depends on the type of fastening of the cladding layers to the supporting frame, the arrangement of frame elements, the presence of sealing and vibration-damping layers, the percentage of air space filled with sound-absorbing material, the influence of the wave coincidence frequency, etc. Currently, standard methods for calculating the soundproofing performance of frame structures do not take into account the full diversity of their design solutions, necessitating experimental measurements. The objective of this study is to obtain experimental data on the soundproofing performance of frame-and-sheathing structures on a double-spaced metal frame. This is accomplished by testing frame-and-sheathing structures with different types of cladding layers in a reverberation chamber and comparing these results with calculated values according to the methodology of the regulatory literature. Results. Using calculation and experimental methods, the frequency characteristics of frame-and-sheathing structures with a spaced framework were obtained. It was found that the calculated values do not agree with the experimental ones in the low-frequency range from 100 to 315 Hz, where the calculations underestimate the sound insulation capacity. It was shown that the presence of vibration-damping tape increases the sound insulation capacity of frame-and-sheathing partitions by 2–4 dB. A two-layer cladding layer of cement-bonded particleboard and gypsum board is virtually identical in sound insulation characteristics to layers of cement-bonded particleboard and gypsum fiber board in a frame-and-sheathing partition system. Conclusions. New data have been obtained on the sound insulation properties of frame-and-sheathing partitions on a double metal frame using various cladding materials. It is shown that the current normative graphical-analytical method for calculating the sound insulation of frame structures can underestimate the final values and requires clarification to take into account the influence of the type of frame system. |
