J247_197105 INSTRUMENTATION FOR MEASURING ACOUSTIC IMPULSES

The purpose of this SAE Recommended Practice is to provide guidelines for selection and application of instrumentation for measuring sound pressure and body cavity over-pressure inside a passenger car, as typified by that generated during the deployment of a passive passenger restraint system(s). The objective is to achieve uniformity in instrumentation practice and reporting of test measurements. Use of this recommended practice will provide a basis for meaningful comparisons of test results from different sources.
