- The 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.
- Megaphones are useful, portable devices for someone who's guiding a group of protesters, for a movie director who's working with a lot of actors on a large set, or for cheerleaders who want their voices to carry over the roar of a crowd of football fans.
