When you activate the horn it should drown out all the sounds like engine prome mover and bell also ambient since the horn is so loud for Sear simulations horns it drowns out all the sounds this should be added because it would be super realistic this could be an update amd it would not even require new horns also an example is in the video below skip to 1:31
So you want all other sounds to be muted when the horn sounds or just make them more quiet? I don't even know if this is technical possible in Unreal, but theoretically to duck all other sound sources (make them more silent) should be more realistic than to completely mute them off. I mean the other sounds also don't just disappear in reality, the horn is just so loud that you barely notice anything else. But that's a difference to no other sounds at all.
