There is no such thing as a silent firework and any retailer that claims to offer totally silent fireworks packs isn’t being truthful. It’s not possible for a firework to be silent due to the noise produced by the lift charge and the explosion of the shell in the air. All fireworks, even quiet fireworks, will make some noise when the lift charge fires but low noise fireworks will not have any loud bangs when the effect bursts in the sky. Quiet fireworks are achieved by reducing the lift charge repellant, minimising the burst of the shell, and removing the salute.
