Sound Deadening Tips
In soundproof rooms, sounds do not carry outside the room. (hi-fi audio system in the room image by Pavel Losevsky from

To deaden the sound in a room you must create an environment that obstructs noise and soaks up sound to stop it from echoing between the floor and ceiling or wall to wall. When you enter an optimal recording space, you notice that your voice sounds quieter, the air feels muted or still and sounds do not carry beyond the immediate environment. While not all rooms are ideal for soundproofing or sound-deadening, there are ways to minimise noise reproduction that can dramatically alter the sound quality of a room.


Carpeted floor promotes less reverberation of sound between the ceiling and floor. Add a thick rug over wood floors. If you already have carpet but it is thin, try adding a rug that covers any wide, open area of the floor. To contain sound for a short-term project, add temporary sound absorbers like moving blankets to floors and walls.

Window Treatments

Windows allow sound into a room and also create a reflective surface from which noise can bounce back into the room. Heavy curtains work best to absorb noise inside and quiet outdoor noises. Thicker fabrics, such as velvet, are optimal; layer curtains for the best results.

Sound echoes off of blank walls, so the more you can break up your room with furniture, wall hangings and textured wall coverings, the less sound will bounce back into the room. Larger rooms are more difficult to control for sound, but well-placed, solid objects will break up sound waves and lower the overall noise levels. The more cluttered your room, the less sound will echo.
