Question

What is the advantage of having conical openings in horns, megaphones etc?

Answer 1

Hi there. The advantage of having conical openings in horns, megaphones, and even our ears! is that a cone-shaped opening gives a more uniform sound field. The cone concentrates the sound power in a narrow direction and reduces the spreading out of the sound waves, therefore, the sound becomes louder in the direction where the cone is pointing.
