Megaphone

Megaphones are a type of public address system that is used to amplify the sound of someone’s voice. They can be found in a variety of settings, such as classrooms, concert halls and sporting events. The megaphone amplifies the human voice by increasing the volume and projecting it farther than would otherwise be possible.

Megaphones have been around for many years and they are still being utilized today because they provide an inexpensive way to share messages with large groups of people.

The word “megaphone” was coined by Nobel Laureate Dr. Rudolf Koenig at the end of 1888 or beginning of 1889 from two Greek words: mega (meaning big) and phone (meaning voice). Megaphones project the human voice mechanically with more force than loudspeakers, which increases its intensity without straining the vocal cords.
