Coaches, teachers, and tour guides will often use megaphones to project their voices over a crowd or to a large group of people. With the 20-Watt Megaphone, users can not only project their voice, but can also create a 10-second message recording for playback, or utilize the siren feature. For speaking, recording, and using the siren, there is volume control to lower or louden the sound.
