WebbMegaphones don't simply aim the sound that you're already making, they can actually draw more volume from your mouth in the first place. This is because whenever a sound wave … WebbMegaphone : Megaphone is a horn-shaped tube. Megaphones are used for addressing a small group of people. Speaking tube is a hollow tube– one end is the speaker's end, whereas the other one is the listener's end. In these devices, the sound waves suffer reflection repeatedly and the energy of the waves remains confined to the tube.
