This article discusses the various attributes needed in public address (PA) systems for use by law enforcement for training and simulation applications.
Abstract
Training and simulation is more important than ever in law enforcement. The choice of a public address (PA) system will ultimately determine the overall effectiveness of the training and simulation programs in law enforcement. This article describes four attributes or elements of effective PA system. Volume is an essential element for training and simulation programs, as well as the clarity of the audio. Well-designed loudspeakers supply both volume and intelligibility. In addition, a quality PA system will include several integral components beyond the loudspeaker which are best centralized in a well-integrated, self-contained equipment rack and mounted or situated in a protected environment. Even though the main audio source for training exercises is likely to a human voice, any number of training and simulation exercises may benefit from audio beyond the human voice. The ability and availability of additional source material, such as gunfire, alarms, sirens, and other audio cues are relevant to these training exercises. Lastly, a reliable PA system should serve multiple purposes, allowing it to have dual functionality as well as durability. Reliable and durable PA systems that provide intelligible audio go a long way in benefiting every officer in the program.
