Soundproofing is a technique used to improve the quality of sound in a room. Improving the quality allows the listener to hear the produced sound more accurately, which enhances the listener experience -- regardless of whether the sound being produced is coming from studio speakers, a live instrument or a person's voice. Using recycled materials is a great way to help the environment and drastically lower the cost of soundproofing your home studio.
Collect recycled materials for soundproofing. The best materials are generally soft and good at absorbing physical impacts. Shipping material, cardboard boxes and packing foam are excellent absorbers of sound. You can easily find these types of materials for free at grocery stores and chain retailers. Old pillows, blankets, and rugs also are great for absorbing sound.
Place collected materials around your home studio to remove standing waves. Standing waves, one of the biggest problems in home studios, occur when two reflective surfaces in a room, such as two walls or the ceiling and the floor, are parallel to each other with a sound source in between. To combat standing waves, attach flattened or broken-down cardboard boxes, blankets, foam or other collected recycled material to the walls of your studio with picture-frame nails or glue. Cover as much surface of the walls as possible.
Place old pillows and rolled up blankets into all the corners of your studio to remove echoes. Corners magnify an echo's volume just like cupping your hands around your mouth makes your voice louder.
One way to improve sound quality after soundproofing is to adjust where your sound sources are in relation to walls, windows and doors. Moving the sound sources away from these surfaces will instantly improve your home studio's sound.
