Abstract

This research paper describes airborne soundproofing of multilayer light enclose structures at the stage of designing and reconstruction of residential buildings, with the help of which it is possible to obtain a sufficiently reliable calculation, representing the correct passage and radiation of the sound stream in these structures, taking into account the finiteness of the dimensions, fixing conditions, physical and mechanical characteristics of materials and the method of proper installation.

Highlights

At present, in the Republic of Uzbekistan, special attention is paid to ensuring the well-being of the people, which is the corresponding goal of implementing the tasks identified in the Strategy of Actions for the further development of the country for 2017–2021 [1]
An urgent task is to ensure the acoustic comfort of the premises, associated with the rational choice of the enclose structures at the design stage
An increase in the sound insulation of multilayer structures is observed at medium and high frequencies lying above the resonance frequency of the mass – elastic – mass system, approximately in an octave

Summary

Introduction

In the Republic of Uzbekistan, special attention is paid to ensuring the well-being of the people, which is the corresponding goal of implementing the tasks identified in the Strategy of Actions for the further development of the country for 2017–2021 [1]. One of the main tasks at the design stage is the use of lightweight multi-layer enclosing structures with a relatively small mass that allows to reduce the load and reduce the material consumption of building construction. An increase in the sound insulation of multilayer structures is observed at medium and high frequencies lying above the resonance frequency of the mass – elastic – mass system, approximately in an octave.
