Investigation of Sound Insulation of Light Multi-Layered Enclosures
Journal Title: Современное промышленное и гражданское строительство - Year 2017, Vol 13, Issue 4
Abstract
This article presents the results of theoretical and experimental studies about sound insulation of multi-layered light barriers. Calculation of sound insulation of structures was performed according to the theory of self-consistency of the parameters of external sound fields and the wave field of fence oscillations developed by the scientific school of professor M. S. Sedov. This method makes it possible to investigate the passage of sound through a multi-layered enclosure taking into the account its dual nature (resonant and inertial passage) to determine the ultimate sound insulation of fences and their internal reserves; they are necessary for the development of rational soundproof solutions for multi-layered light fences. The main ways to increase sound insulation by using internal reserves are defined as follows: to reduce the resonant sound transmission; to reduce the cylindrical rigidity of the fence without significantly changing its mass with the use of layered fences of different thicknesses; the introduction of acoustic separation between the lining and the frame due to the presence of a sound-absorbing layer in the air gap; and to reduce the modulus of elasticity of the material of this layer. The obtained results of the research are recommended for introduction in the design of interior partitions in the projects with residential and public buildings.
