Question

an example of chemical energy being converted to sound energy.

Answer 1

Energy stored in a plastic explosive is chemical until it is detonated! Then it converts into heat, light and sound etc! Same with fire-crackers even. Or a lighting a match for that matter discharges sound energy!!

Answer 2

You hear an explosion, which is a change in chemical energy, whenever you hear a car go by- the noise is the explosions in the cylinders
chemical energy in a battery is converted to sound in a boom box
