SAE Recommended Formats for Presenting Acoustical Data

Automobile manufacturers recently requested the help of the SAE Acoustical Materials Committee to develop standard data formats that could be used by suppliers to present data on NVH products. An SAE task force with representatives from material suppliers and from OEMs chose formats covering a broad range of acoustical tests commonly conducted in the automotive industry. These formats cover both material and vehicle tests. They include details on samples and test conditions and graphs with preferred axes and data ranges. SAE recommended practice J2629 will be issued that describes the use of these preferred formats for acoustical data. The automobile manufacturers have requested that all suppliers of NVH products use these formats to present results from this point onward.
