Has anyone got the sound of the "goblin siren"

You can find a lot of sound clips at http://www.knightmare.com/clips/, although they're all quite old and not very hi-qual.

Hello, and welcome to the forum. Others have requested the goblin horn sound before, and while it isn't available online as a sound file, you could always create your own using a computer microphone, speakers, sound recording program and the Knightmare videos on YouTube (which currently comprise nearly every episode). Happy hunting.
