Abstract
The influence of the total loss factor of building elements on their sound insulation is well known, although the problem of measuring this value was up to now not solved completely. This article describes an improved measuring method for total loss factors of building products especially for heavy elements. Furthermore, the principle of conversion of different results for transmission loss of the same type of wall under different mounting conditions using the total loss factor is presented. Measurement results in a transmission suite were examined and corrected with values derived from the improved measuring method.
