Development of Universal Ducting Envelopes for S-280 Shelter.
Abstract
The objective for this noise study was to reduce the noise levels within the S-280 Shelter to an NC-55, using eight combinations of duct configurations with single and double environmental conditioning unit combinations operating in the high cooling mode. The second purpose of this noise study is to provide the project office with a series of alternate duct configurations to meet the requirements for different types of shelter arrangements.
