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.
