What is the effect of a concussion mortar?

The effect of a concussion mortar is to create a loud noise and jarring shock. This type of mortar is specifically designed to produce an impactful sound that can complement visual fireworks displays. The sound generated can enhance the experience for the audience, adding to the dramatic flair of the event. The noise and shockwave produced by a concussion mortar are intentional effects, meant to simulate a strong auditory presence that engages spectators.

In contrast, options related to silent displays, aerial launches without sound, or the emission of colored smoke without producing any noise do not align with the primary purpose of a concussion mortar, which is focused on generating a powerful auditory effect.
