More about this voice

How the bullhorn sound is built

Narrow band: everything below 600 Hz and above 3.5 kHz is cut, so there's no chest and no air.
Honk: a 6 dB boost at 1.8 kHz, the frequency small horn speakers ring at.
Drive: distortion at 0.55, mostly mixed in, for the cracked edge of an overdriven horn.
Squash: an 8:1 compressor, so whispers and shouts come out about as loud as each other.

Three loudspeakers

Clip	Change	Use it for
Bullhorn	none	Protest chants, coaches, comic shouting
Cleaner PA	Distortion 0.25	Announcements, a train platform, a school hall
Stadium	2.5-second reverb added	Sports intros, arena announcements

Keep your audience

Because the compressor flattens everything, the megaphone voice is loud even when you speak softly. In a call, use it for a line or two and switch back, and keep it down if others are wearing headphones.
