Renting an apartment usually comes with limits on decorating. If find that your wooden floors and high ceilings create echoes and vibrations, try framing your favourite art with padded frames to keep your neighbours and landlord happy.
You can lay down rugs to deaden sound, but adding sound-insulating frames or fabric-covered, padded panels to the walls helps too. In his book, The First Apartment Book, Kyle Shuman suggests making fabric-covered, padded panels to help minimise travelling noise. You can make use of whatever fabric you can get your hands on. It's a cheap idea that will help muffle sound in just about any space -- hallways, music studios and living rooms.
To make the panels, cut fabric of your choice to fit a 36-by-48-inch foam-core board, leaving an extra 2-inch border. Next, cut a roll of batting to fit the board, leaving an extra 1-inch around the edges. Place the batting on top of the board, fold the extra batting over the edge and duct tape it down. Lay the board on the fabric square (batting side down) and wrap your fabric over, one side at a time, and duct tape the extra material to the back.
If your landlord bans the use of nails for hanging pictures, stick the panels in place with sticky-back Velcro. Click the link below to check out more landlord-friendly ideas for apartments.
