Title:Laboratory Measurement of the Airborne Sound Barrier Performance of Flat Materials and Assemblies
Issuing Committee:Acoustical Materials Committee
Scope:This SAE Recommended Practice presents a test procedure for determining the airborne sound barrier performance of materials and composite assemblies commonly installed in surface vehicles and marine products.This document is intended to provide a means of rank ordering barrier materials according to their sound transmission loss. At each test frequency the transmission loss (TL) is projected from the measured noise reduction of the test specimen using a correlation factor (CF). The respective CF for the test condition is determined as the differences between the measured noise reduction (MNR) of a homogeneous limp panel, such as lead, and its calculated field-incidence transmission loss. Latitude is permitted in certain test conditions that do not necessarily conform to all of the acoustical requirements of ASTM E 90. This method facilitates the evaluation of automotive materials and assemblies under conditions of representative size, edge constraint, and sound incidence so as to allow better correlation with in-use barrier performance.
