More Information On Megaphone:
A megaphone, speaking-trumpet, bullhorn, blow the horn, or loudhailer is usually a portable or hand-held, the cone-shaped acoustic horn used to amplify a person’s voice or other sounds and direct it in a given direction.
The sound is introduced into the narrow end of the megaphone, by holding it up to the face and speaking into it, and the sound waves radiate out the wide end.
A megaphone increases the volume of sound by increasing the acoustic impedance seen by the vocal cords, matching the impedance of the vocal cords to the air, so that more sound power is radiated.
It also serves to direct the sound waves in the direction the horn is pointing. It somewhat distorts the sound of the voice because the frequency response of the megaphone is greater at higher sound frequencies.
The initial inventor of the speaking trumpet is a subject of historical controversy. There have been references to speakers in Ancient Greece (5th Century B.C.) wearing masks with cones protruding from the mouth in order to amplify their voices in theatres.
Hellenic architects may have also consciously utilized acoustic physics in their design of theatre amphitheaters.
Portable megaphones are widely used for crowd management and mass communication. When needing to communicate information or directions to a large crowd of people in one place, an electric megaphone is valuable when other public address systems are not present.
