Abstract
The analytical solution of the problem of sound and vibration passage through structures and joints requires determining the elastic-dissipative properties of structural and sealing materials of translucent structures: the dynamic modulus of elasticity and loss factor. In this paper, the parameters of the dynamic modulus of elasticity and loss coefficient of some well-known building materials are investigated and experimentally established in comparison with previously obtained data from other authors. To automate and accurately measure the coefficient of dynamic characteristics of materials, a measurement technique was used, using Zetlab software and measuring equipment. When measuring the dynamic modulus of elasticity of sealing materials, LDS measuring equipment was used. The refined values obtained for the dynamic modulus of elasticity and the loss factor of materials allow them to be used in vibroacoustic calculations of translucent structures.
