Title:

Improving Intelligibility of Airport Terminal Public Address Systems: Introduction to ACRP Report 175

Accession Number:

01664279

Record Type:

Component

Abstract:

ACRP recently published Report 175 which provides guidance to airports to improve the speech intelligibility of airport PA systems through design and better operation. Audible announcements in airport terminals are often hard to understand. Given that the airport terminal environment is dynamic, the speech intelligibility of public address systems can decline and people can find it hard to understand announcements due to background noise and/or poor system design. Understanding announcements is even harder for (1) hearing-impaired travelers, (2) people for whom English is not their native language, and (3) distracted travelers. Poor intelligibility in public address systems degrades the efficacy of fire alarm notifications and other public service and emergency announcements that are critical in airport terminals. This paper introduces the new report and discusses case studies provided in the guidance document.
