A soundproof room is used to minimize outside noise and isolate sound. It is difficult to create a truly soundproof room, but the best solution is to dampen or absorb as much sound as possible. A soundproof room is essentially a room within a room, with two walls separated by thick insulating material. Soundproofing materials are available, including foam panels, special curtains, and suspended grids of acoustic panels. The floors and ceilings must also be insulated. A soundproof room can solve noise problems for musicians and entertainment system owners.
A soundproof room is a purpose-built space where almost all generated noise cannot escape. Recording studios routinely use these rooms to keep outside noises to a minimum and isolate individual instruments or vocals. Research engineers can also use a soundproof room to measure a machine’s audible output. Apartment dwellers and homeowners often create these rooms to keep the sounds from entertainment systems to a minimum.
Creating a room that is truly soundproof is not easy. To understand the difficulty, a crash course in acoustics can help. Amplifiers and speakers generate sound waves, which must travel through a sympathetic medium to reach the listener’s ears. In a typical room, the air is average. Sound energy travels through the air until it strikes a surface such as a wall, but a single uninsulated wall does not block all sound waves from penetrating the surrounding area. It might block the higher frequencies from getting out, but the low frequencies continue through the wall and back into the air. This is why a neighbor’s loud stereo can sound like a bass and drum solo in your apartment.
An ideal room that is soundproofed would eliminate all possible methods for sound waves to travel, but this would include the air you would breathe. Instead of total vacuum, the best solution is to dampen or absorb as much sound waves as possible. A soundproof room is really a room within a room. There are two walls separated by a void filled with thick insulating material. The wall studs are staggered, so there is no physical connection between them. Sound waves that penetrate the interior wall of the room must first pass through the sound-absorbing insulation and then through a second wall barrier. This eliminates most, but not all, distracting noises.
In a professional recording studio, the room may actually be lined with lead sheeting for maximum sound absorption. This would be too expensive for the average homeowner, but less expensive soundproofing materials are available. Most work on the principle of damping or deflecting sound waves. Foam panels with vertical and horizontal slats can be placed on the inside wall of a soundproof room to deflect sound waves away from the outside wall. The doors to this room are also designed for soundproofing. The door to a professional recording studio alone can cost thousands of dollars.
Many soundproof room designs don’t include windows, but it’s not impossible to install a soundproof window system. Glass is an excellent carrier of sound waves, but a double or triple pane system can dampen vibrations before they are dispersed into the outside air. If air is removed between the panes and the sash is installed correctly, a window can be soundproofed effectively. For even greater soundproofing, special curtains made of heavy materials can be hung on the windows.
The floors and ceilings of a soundproof room must also be insulated with sound-absorbing materials. A solid concrete floor is usually best for minimizing sound waves, but some designers suggest a “floating” floor plan, where the sub-floor is covered in a neoprene-based insulation material and the floor essentially floats above it. The ceiling can be modified with a suspended grid of acoustic panels and additional vacuum blown insulation.
Having a virtually soundproof room can solve a lot more problems than it creates. Musicians can play higher instruments without fear of disturbing the peace, while entertainment system owners can use them at any volume.
