The term 'Called by Loudspeaker' can be summarized as a job that requires someone to be PAGED, which is a five-letter word. This job involves using a loud speaker to call out a person's name or message in order to get their attention. It is often used in public places such as airports, shopping malls, and other large venues. This job is usually done by an employee of the venue, but can also be done by a volunteer. The person being PAGED must then respond to the call in order to receive further instructions.
