Place this clip at the moment the door stays shut in your edit, and lead into it with the Door Knocking Sound Button so the knocking happens first and the plea follows immediately after.

This is a short voice clip of a person speaking in Portuguese, repeating the plea 'Me deixa entrar', which means let me in, over about seven seconds. It gives a listener an urgent, slightly awkward and funny feeling, like hearing someone stuck on the wrong side of a door.
