Many apartments and homes have thin walls that allow sounds to permeate easily. Blankets help muffle sound. Soundproofing typically blocks out medium- and high-frequency sounds the most easily. Unfortunately, low-frequency sounds such as deep voices and humming machinery can be challenging to block out. Unless you have a neighbour who plays a bass instrument, you probably won't hear too many bass noises. Perfect soundproofing is typically impossible, but you can block out the majority of sounds.
Remove any materials hanging on the wall, such as paintings and posters.
Push the furniture in the room toward the centre of the room.
Place a stepladder in the corner of the room. Step onto the ladder while holding a blanket.
Nail the corner of the blanket to the edge of the room. If you want to avoid leaving a hole in your wall, use a thick tack, masking tape or duct tape. Place the tape over the blanket. Tape the blanket to the top of the wall and the ceiling.
Attach the other corner of the blanket to the wall.
Attach another blanket to the other side of the wall. Attach blankets to all of the walls in the room.
Move the furniture back into place.
You can purchase special soundproofing blankets. These blankets typically are more costly than conventional blankets, but they soundproof more efficiently.
