Abstract

The article presents a new joinery and construction material made of corrugated veneer. The material under consideration can be used to create lightweight internal enclosing structures of residential premises (interior partitions) and for interior decoration. Within the framework of this study, the tasks related to the determination of sound insulation properties and characteristics of a new joinery and building material and the search for ways to improve its design are considered. The analysis of the regulatory requirements for interior partitions of residential premises and the requirements of standards for the experimental determination of the degree of isolation of air noise by enclosing structures in field conditions is carried out. Methods for determining the sound insulation properties and characteristics of various materials and structures, as well as equipment used for research, have been studied. An experimental installation has been developed to evaluate the effectiveness of insulation from air noise of samples of the proposed joinery and construction material. Samples of the material necessary for the experiment were made, and an experiment plan was drawn up. It has been established that the highest efficiency of isolation from air noise is achieved in the high frequency range from 4800 dB and above. In the area of low and medium frequencies, the sound insulation of the material under study is not effective enough, which requires the use of additional sound insulation layers. The assessment of ways to improve carpentry and construction material to improve its sound insulation properties in the low and medium frequencies has been carried out.
