'Silencio' is used to make things silent, like another person, but to like block out sounds the Imperturbable Charm is used, like how Molly Weasley used in 12 Grimmauld Place in OotP to block out any sounds from the meeting so that the children wouldn't listen. I'll show you.
Chapter 4 - 'Number twelve, Grimmauld Place'
"You want to be careful," said Ron, staring at the ear. "If Mum sees one of them again..." "It's worth the risk, that's a major meeting they're having," said Fred. The door opened and a long mane of red hair appeared. "Oh hello, Harry!" said Ron's younger sister, Ginny, brightly. "I thought I heard your voice." Turning to Fred and George she said, "It's no go with the Extendable Ears, she's gone and put an Imperturbable Charm on the kitchen door." "How d'you know?" said George, looking crestfallen. "Tonks told me how to find out," said Ginny. "You just chuck stuff at the door and if it can't make contact the door's been Imperturbed. I've been flicking Dungbombs at it from the top of the stairs and they just soar away from it, so there's no way the Extendable Ears will be able to get under the gap."
From dictionary.com:
imperturbable
adj : not easily perturbed or excited or upset; marked by extreme calm and composure; "hitherto imperturbable, he now showed signs of alarm"; "an imperturbable self-possession"; "unflappable in a crisis" [syn: unflappable]
You can just use that instead of the Silencing Charm, and it makes loads more sense. I always do. ;)
