How do you say "Shut up!" in Russian?

Woken up by my wee one around midnight last night. It's nothing unusual, as she sometimes calls me when she wakes up from a bad dream. Told her to go back to sleep and it was OK.

Then, just after I fell asleep again, there were some loud conversations coming from the next-door's back garden. It was around 1.30am for goodness sake!!! I know they don't smoke inside their house and always go out in their back garden for smoking. But why did they do such a thing at that time of the night? And all this talking and laughing!! (Pity that I couldn't understand the foreign language.) As I couldn't be bothered to open the window or do anything about it (I was too tired), I just covered my ears and closed my eyes.

Mentioned about the last night to my neighbour, who lives the other side of the noisy next-door. She told me that the banging of the doors in the next-door was terrible last night. And another neighbour, who lives next door to me (not the noisy house), also told me that she was woken by the talking at the back garden. She, too, was pretty annoyed. Later found out that my wee one was woken up by the banging from the next door...

Thanks to the poor quality of my sleep last night, I've been ratty today. Strangely I haven't seen any of the people who live next-door today. To be honest, I was waiting to ask them "Did you have a good time last night?" I should complain the noise to their landlord the next time it happens. Can't be bothered to tell them in their faces because they might pretend not understanding English. How dare they ruin my sleep! Their loud Euro pop in the daytime is bad enough. (Pity that the music sounds so cheap and untasteful.) I don't know how they can be so ignorant. I wonder if such ignorant behaviours are normal in the country which they came from...
