Measurement of the Efficiency of Damping Materials
The SAE J671/58 Standard deals with the measurement of all properties of sound dampers and underbody coatings. With respect to the acoustical measurements, there are only general specifications about what to measure and how to measure it. The object of the present study is to supply detailed information about the practical realization of the measurement itself. Experimental results are supplied, and special attention is paid to the reliability and the accuracy of the method proposed in this paper.
