Abstract
PA (Public Address) system is usually installed and frequently used in multipurpose halls. But there are no standard indices for evaluating the effect of PA system on speech transmission quality. In this study a subjective experiment on "easiness of speech perception" was carried out with a simple PA system in a multipurpose hall. As a result, factors that influence "easiness of speech perception" such as characteristics of room acoustics, sound source, and amplified sound were presented.
