What type of pyrotechnic device creates a loud explosive sound?

The type of pyrotechnic device that is designed specifically to create a loud explosive sound is known as a maroon. Maroons are often used in theatrical productions and special events to produce a significant auditory effect that can be startling or attention-grabbing. They are typically deployed for dramatic moments, signaling, or to enhance the impact of a scene.

While flash pots, sound charges, and bang devices may also produce sound effects, they serve different primary purposes. Flash pots are intended for visual effects as they create a burst of flame or light, while sound charges and bang devices are typically more focused on producing specific sound effects or enhancing an audio atmosphere rather than delivering the intense explosive sound characteristic of maroons. Consequently, the maroon stands out as the designated device for creating loud explosive sounds in various contexts.
