Acoustical Benefits Resulting from Insulation and Air Leakage Control in Family Housing Units

摘要

In an investigation sponsored by the Navy Family Housing Office, a series of tests were conducted to determine the improvement in acoustical sound transmission loss resulting from housing envelope energy conservation retrofits involving increasing the insulation level and/or controlling the air leakage. The data generated will be utilized in selecting energy conservation measures with maximum acoustical benefits, for retrofitting family housing units near aircraft operations, where excessive noise has been a problem. Three wall and two roof/ceiling test structures were constructed to be representative of those in present Navy Family Housing Units. The sound transmission loss and air leakage rate (resulting from an induced pressure differential) were determined for each basic construction. Subsequently, various retrofit measures were performed, designed to improve sound transmission loss, thermal performance and/or air leakage control. Following the retrofit, the improvement in air leakage rate and sound transmission loss were again determined.
