QUILITE® Aircraft Run-up Shelter

PURPOSE	This Shelter was built for American Eagle Airlines (subsidiary of American Airlines) to reduce noise that disturbs near-by residential areas. The Aircraft tested in this shelter are SAAB A-340 Turbo-Prop transports.
DESIGN	The enclosure is a "U" shaped structure. Its width is approximately 88 feet and its depth is approximately 64 feet. The total height of its walls is 20 feet. The base of each wall has a 4 foot high vertical concrete block section which is topped by a 16 foot high QUILITE section that extends the height to 20 feet
QUILITE	The nominal size of QUILITE panels used in the wall is 4 feet X 8 feet. The total area of QUILITE used approximately 3100 sq. feet.
LABOR	Installation labor, after post emplacement, used 3 days to install the panels. An individual panel required approximately 5 minutes to install.
PERFORMANCE	Acoustic measurements indicate that the average wall sound transmission loss between 63Hz and 8000Hz is approximately 20dBA. Also, at a location 200 feet in front of the open side of the enclosure, measurements indicate that the reflected sound pressure level average, between 500Hz and 8000Hz, was 11dBA lower than direct noise projected from the enclosure.
