There are as many reasons for needing to soundproof a room as there are ways to soundproof it. Many things in a bedroom will naturally absorb sound--such as pillows, blankets, mattresses, curtains, furniture, clothes strewn about the floor, and so on--but other options exist that will be more effective while still being eco-friendly.
Curtains of any kind will absorb sound, but some kinds help you soundproof your room better than others. To trap the sound, use the best option on the market--blackout curtains. The curtains were developed to keep light from entering and escaping, so many brands out there will boast their ability to block out up to 99 per cent of their light. Some brands, such as Eclipse Curtains, will also claim to block 40 per cent of noise. As a bonus, these will also help with your heating costs by trapping in heat during the winter and by keeping out light and heat during the summer. Blackout curtains are hung like normal curtains, so if you already have curtains in your room, then it's simply a matter of replacing them. If you don't have curtains, you are going to need to buy a rod.
Blackout curtains are available at almost every major retailer and range from £13 to £84.
Audimute has a variety of green, eco-friendly sound absorption products. The company carryies insulation made from recycled tires, sound absorption sheets and handcrafted acoustic panels.
The customisable acoustic panels can be designed to look like paintings, resulting in a very stylish and visually appealing option. They have the ability to reduce echoes and reverberation by as much as 100 per cent in a properly treated space. They are also very easy to install. Much like hanging a picture or painting on the wall, the panels don't require anything beyond a few nails to support the weight. Their easy set-up makes them very portable as well, should you consider rearranging your room.
The cost of Audimute products are relatively inexpensive when compared to other leading sound absorption products. For the Sound Absorption Sheets, the cost runs between 60p and 90p per square foot, while the panels fall in the range of £3 to £7 per square foot.
Egg cartons have long been thought of as a good material for soundproofing. Although not very effective, they can prevent some noise from escaping your room. In order to do this, you're going to need to save up many egg cartons--polystyrene plastic cartons work the best--and line your room with them. By draping blankets, sheets or anything you can find over them, you will be enhancing their effectiveness. Even with the sheets, its soundproofing is only a fraction of the more sophisticated products out there.
