This SAE Recommended Practice establishes the test procedure@ facilities@ and instrumentation for determining the noise reduction characteristics of materials commonly installed in ground vehicles@ marine@ products@ and aircraft to reduce noise levels. This document is intended to provide a means of rank ordering materials by utilizing facilities that do not necessarily meet all of the acoustical requirements in ASTM E 90@ Laboratory Measurements of Airborne Sound Transmission Loss of Building Partitions. Latitude is permitted in certain test conditions to allow better correlation with in-use acoustical results.
