How to Convert My Closet Into a Soundproof Booth

Creating a soundproof room gives you a place to practice and record music without disturbing those around you. Whether you are a musician or an aspiring music producer, a soundproof space will allow you to practice your craft. When using the room as a recording studio, soundproofing gives your music and vocals a clear quality and prevents sounds from other rooms from leaking into your recording. When using the room for practice, soundproofing keeps the music in the room. A soundproof room can help keep you on good terms with your neighbours, and leave you free to practice and record.

Spread the clothing equally along the rods of the closet. Clothing absorbs sounds from other rooms, helping to create a soundproof environment. A large walk-in closet with clothing hanging on all sides works best, but any walk-in closet will work.

Spread a blanket over the clothes to create solid, sound-absorbing walls.

Cover any bare walls with additional blankets. Sew small plastic loops every 4 inches along one side of the blanket. Pound nails into the wall every 3 1/2 inches as high as possible. A little slack in the blankets adds to the soundproofing for the room.

Hang another blanket over the top of the door, allowing the majority of the blanket to hang over the door. Close the door, trapping the blanket into the crevice.

Remove the blankets and nails to use the space as a closet after recording.

Remove clothing, hanging rods and shelves. Remove anything else in the closet, leaving bare walls and a floor. If the closet is carpeted, leave the carpet intact. It adds to the soundproofing.

Measure the length, width and height of the walls and ceiling. Acoustic tiles come in 1-foot squares, making it easy to compute the number of tiles necessary for your closet. The tiles are hard-backed pieces of foam. Many have waves or finger-like projections to further interrupt sound waves.

Spray an X about the size of a tile on the wall with the adhesive spray, starting in one corner at floor level. Spray the entire back of the first tile. Allow the spray to dry until tacky. This should take about 30 seconds. Press the tile into place. Hold the tile until the adhesive sets, about 30 seconds. Let go of the tile. Repeat to cover all exposed wall surfaces.

Place tiles on the ceiling. Leave a 6-inch area free around any light fixtures. Cover the back of the door with foam acoustic tiles. Trim the foam near the hinge with scissors so that the door opens smoothly.

Measure the floor of the closet. Cut the 2-inch foam sheet to fit the floor. Place the foam on the floor of the closet. If you don't have foam, place a thick blanket on the floor. This method works well to block out sound from outside the room, but it will not block out low-frequency sounds such as those from drums or a bass guitar.


If you need to cut your tiles to size, make careful measurements, then cut the tiles with a craft knife on an appropriate work surface. When making a temporary soundproof room, don't forget the shelves of the closet. Clothing that is stored on the shelves can stay put. Hard objects, such as boxes, need to be covered with a blanket.


Soundproofing will prevent SPL (Sound Pressure Level) noise. This is the sound that can interrupt a vocal high tone musical recording. Soundproofing will not fully block STC (Shock Transmission Conduction). This is low level sound, such as that made by a bass guitar or drums, that carries through walls and floors. In order to create a room that blocks these sounds, you must build an entire "floating room," with 6- to 8-inch gaps between the original and "floating" walls and floor. Few closets have the room to make these modifications and still allow room for a person and sound equipment.
