How do you use the blueprint event generator in the particle system?

So I was I am tasked with making fireworks sound match the fireworks. The fireworks are in a complex area and I am running out of time and I must complete the level to test the sound matching the system. I was looking to see if you can attach sound to a particle system some how and I found the Event Generator. The Even Generator has a type node for the level blueprints so I was wondering if I can attach sound to it through this way. Also what can I do with this type?

Hi, i know this is an old post and all but i am a sound designer and id like to know this exact same thing as well. Anyone ?
