What effect does a horn connected to a transducer have?

A horn connected to a transducer plays a crucial role in sound production, particularly in enhancing audio performance. When a transducer, which converts electrical signals into sound, is attached to a horn, it not only increases the overall volume of the sound generated but also allows for better directional control of that sound. This is because the horn effectively shapes and focuses the sound waves being produced, which enhances their propagation and intensity.

The design of the horn amplifies the sound through a process known as impedance matching, allowing the transducer to work more efficiently. This results in a louder and clearer sound, especially beneficial in large venues or open spaces where ensuring that sound reaches the audience is essential. The horn's structure helps direct the sound waves in a specific direction, making it possible to target the audience more effectively.

In contrast, other effects such as decreasing volume, providing ambient sound, or eliminating distortion are not functions associated with a horn connected to a transducer. Horns are specifically designed to amplify and direct sound rather than diminish it or serve broader acoustic purposes unrelated to focused sound projection.
