I just came across a sentence which confused me a lot.

In Cambridge Dictionary, there's a sentence:

You should have heard the audience applaud - the noise was fantastic.

I think that the action "applaud" in this context is a past action, so shouldn't it be "You should have heard the audience applauded" instead? Can anyone please explain this type of grammatical structure?
