Airport related residential acoustical insulation demonstration project

TLDR: In this article, the St. Louis Airport Authority undertook a demonstration project to develop firm data on the cost and value of retrofit acoustical insulations for residences in the airport environs.

Abstract: Faced with making a choice between acquiring residences and clearing the property versus acoustically insulating them, the St. Louis Airport Authority undertook a demonstration project to develop firm data on the cost and value of retrofit acoustical insulations for residences in the airport environs. Six wood frame homes, typical of most of the housing stock in the area, were modified using standard available construction techniques and materials in an effort to improve their insulation against aircraft noise. Noise exposure measurements were made before and after modifications. This paper reports the details of the retrofit modifications employed and their effectiveness in reducing exposure to aircraft noise.
