Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

125 The following subject areas would benefit from additional research: • In situ measurement of daytime STI tied to passenger experiences at those tested locations. This kind of test would require coordination and cooperation with airports to a deep level that requires time, access and security logistics. Such coordination and cooperation were not available for this project. Individual airports might choose to conduct such a study as part of their own data collection to develop priorities for renovation of an existing terminal. • The pilot passenger study indicated that experienced passengers at one major U.S. airport tended to tune out PA messages; this is the opposite of the top-down processing model that expects experienced passengers will actively seek information. Additional studies would be useful to determine whether this behavior is specific to certain kinds of experienced passen- gers (e.g., frequent domestic business travelers), generally true across the United States, or only specific to this airport or this region.

TRB's Airport Cooperative Research Program (ACRP) Research Report 175: Improving Intelligibility of Airport Terminal Public Address Systems provides design guidelines to improve public address systems for all types and sizes of airport terminal environments. The guidelines include a summary of data on public address systems, terminal finishes and background noise levels in a variety of airport terminals, identification of acoustical shortcomings, and the results of impacts on existing public address systems. The report provides options for enhancing intelligibility in existing airport terminals as well as ensuring intelligibility in new terminal designs.
