Calculation and Analysis of Loss Factor of Building Materials

Abstract:

In order to describe the damping characteristics of building materials and members, the formula for calculating loss factor which concerns with the internal loss factor and edge losses was derived from the concise physical relationship and, calculations of loss factor of some common building materials and members are presented. Therefore, the loss factor curves of among the walls which made of different materials are gained. It is shown that at low frequency total loss factor (damping) of a building material gradually decreases with the frequency and is also dependent on the thickness of the wall and its longitudinal wave speed, and at high frequency it tends to a constant.
