Abstract:

Currently, the construction and operation of buildings has been paid much attention to this issue, as noise. Prolonged exposure to noise on the human body leads to the development of fatigue, often rolling in fatigue, poor performance and quality of work. Of great importance in the control of noise are architectural planning and construction activities. Leading manufacturers of building materials seek to develop specific products and designs, with good sound insulation. When a new construction, such as building blocks, you must define the index of airborne sound insulation, sound insulation as the main characteristic. The aim of this work is the calculation of the index of airborne sound insulation of walls silicate wall of hollow blocks and determine the average dynamic modulus of elasticity of the material at a known index of airborne sound insulation.
