sounds and brushes/actors

[killed]

I was wondering if it was possible to have a sound played when a player touches a an actor or a certain brush, for example, if you were to walk into a plant, would there be a way to make that plant actor make a noise when you hit the collision box? and the same with brushes, once you walk into the collision of a certain brush is there a way to have it make a noise? thanks for any help anyone can give me
