Possibilities of Using Partitions from Tongue-and-Groove Blocks from the Standpoint of Ensuring Sound Insulation Requirements

One of the most common materials in the construction of partitions between rooms in buildings for various purposes, in particular in residential buildings, are tongue-and-groove blocks. One of the most important indicators of the level of comfort of the human environment is the sound insulation of enclosing structures. Low rates of sound insulation of enclosing structures have a detrimental effect on human health and labor activity. In order to assess the sound insulation of such structures, a series of tests of various partitions made of tongue-and-groove blocks was carried out for compliance with the airborne sound insulation index of the current regulatory requirements. The article considers various options for constructive solutions for partitions made of tongue-and-groove blocks between rooms in buildings for various purposes. The solutions and studies presented in various reference and scientific materials and publications of past years are studied. An analysis of the dependence of the indices of airborne noise insulation of partitions made of tongue-and-groove blocks on the adopted design solutions and test conditions was carried out. A graph of the dependence of the frequency characteristics of all structures for which the analysis of the dependence of airborne noise insulation indices was carried out is given. A comparison of full-scale tests and theoretical calculations of sound insulation of single-layer partitions of a solid section is also given in accordance with the current regulatory documents.
