STRUCTURAL SOUND-TRANSMISSION IN BUILDINGS - COMPARISON OF EXPERIMENTALLY OBSERVED VALUES AND THEORETICALLY EVALUATED VALUES USING THE STATISTICAL ENERGY ANALYSIS METHOD

In the field of building - acoustics the method of Statistical Energy Analysis is used for the calculation of sound transmission in buildings. In consideration of the measured results of structural sound transmission in buildings, two quantities for the calculation have been determined, which cannot be measured directly in buildings. These are the internal loss factor of concrete plates, and the rotational compliance at the plate connections. The influence of these quantities on the calculation of the structural sound transmission in buildings is presented. In comparison of the measured and calculated values an assertion is made concerning the accuracy of the Statistical Energy Analysis Method.
