An acoustic horn is a device designed to amplify sound. It typically consists of a funnel-shaped structure that directs sound waves from a source, such as a speaker or musical instrument, into a larger area. This design enhances the volume and clarity of the sound, making it more audible over distances. Acoustic horns are commonly used in various applications, including musical instruments like brass and woodwind instruments, as well as in loudspeakers for public address systems. The shape and material of the horn can significantly affect the quality and characteristics of the sound produced.
