The application of noise‐control engineering during the design of a new international airport for a future population center presents unique challenges. This airport will be constructed on a site 25 km long and 12 km wide and is 22 km from any populated area. The airport facilities include two international terminals, two domestic terminals, a large mosque, a control tower, a royal facility, and many support buildings. This paper discusses the organization and procedures used to provide noise‐control engineering support to the engineering and architectural firms designing these various facilities. Included is the methodology used in determining the acoustical criteria, the sound isolation and speech privacy requirements for the various spaces. Sound isolation details and unit cost comparisons are presented.
