Comparison between ASTM nnd FAA procedures for determining airborne sound insulation of building facades

Abstract

Variations in sound level measurement procedures and the test results between American Society for Testing and Materials, “Standard Guide for Field Measurement of Airborne Sound Insulation of Building Facades” (ASTM Designation E 966), and the Federal Aviation Administration (FAA) Noise Reduction Audit used to determine eligibility for federal funds, are compared. An empirical analysis is used to compare the results of these two methods whose differences are primarily the type and location of the exterior noise source. The contribution of low‐frequency sound to the noise reduction will be presented. The structures used in the analysis are homes participating in the Stapleton Noise Insulation Program (SNIP). The purpose of the SNIP program is to improve the sound insulation of homes, churches, and schools in close proximity to Stapleton International Airport. Sound measurements using both methods were conducted for a sample of homes of varying construction types before and after the construction modificati...
