How to dampen/muffle sound over time?

Hey guys,

I want to do this effect where when the player dies, all the sounds go muffled over a short amount of time AND drops in volume, kind of like you’re underwater or something, eventually until you hear nothing.

I figure you can get similar effects with low-pass filter but that’s just on cues, right? How do I do the dampening effect for ALL the sound the player is hearing around them (in blueprints)? And can I change the universal volume somehow too, without effecting their config SFX volume when they respawn?

Thanks!
