How do I block the audio and video from this website??

I have NoScript enabled, with a few exceptions on websites I frequent, I also have Flashblock, Cookiesafe, Ghostery, AdBlockPlus, and QuickJava. I just came across this website -

www dot hendershotgenerator dot com,

and audio video began to play immediately. I've never been on this site, and have not made any exceptions. I'm confused as to how this website can play audio and video. Any suggestions?

Thanks!
