That's what those sound effects are? I thought they were just generic stock audio files SE was using for that 'background ambiance' - I'm pretty sure I can hear at least one person in the background apparently carrying out a conversation in English, although what he's saying exactly is unintelligible, but it does at least sound like English.

But I do hear also from time to time a loud "hurrrk!" sound, that always puzzled me as to what exactly it was. Now, this mystery deepens - someone is murdering lalafells in the background! o.o
