Your soundproofing isn’t complete until you’ve soundproofed your ceiling. If there’s anything on the floor above you, sound can easily travel down into your apartment, condominium or home without adequate soundproofing. But how do you soundproof a ceiling? Your approach will vary depending upon whether you’re putting in a new ceiling or you have an existing ceiling. If it’s the latter, you’re probably interested in soundproofing a ceiling without removing drywall or ripping up your existing ceiling.

If you’re building a new ceiling, this is the perfect time to add soundproofing. Whether you’re building a hotel, apartment or multi-story home, guests and residents will appreciate not having to deal with excessive noise from above.

If you have an existing ceiling, you may not want to go through the expense of tearing it out and starting over just to add soundproofing.

Fortunately, you don’t have to. In fact, keeping the existing ceiling and adding more soundproofing may provide even better soundproofing than ripping out the drywall and starting over. Here’s what you need to know to carry out either procedure.

Types of Ceiling Noise to Eliminate With Soundproofing

Before you soundproof your new or existing ceiling, you’ll want to consider the type of noise you’re seeking to eliminate. There are two primary varieties of noise in buildings:

  • Airborne noise: As the name would suggest, airborne sound moves through the air. Sources of noise produce soundwaves that flow through the air until they meet a solid object, such as your wall or ceiling. But hard surfaces can’t totally absorb noise — that’s why sound travels through walls and into other rooms.
  • Structural noise: Traveling through your floorboards, ceilings and walls, structural noise occurs when an object makes a direct impact on a structure. This collision sends soundwaves through the impacted surface, which is why you’ll hear the impact from footsteps or a dropped object upstairs.

How Do You Soundproof a New Ceiling?

So how do you soundproof a brand-new ceiling? You’ll need to use drywall, hat channels — which provide the frame you attach the drywall to — and soundproofing material, like Quiet Batt™ soundproofing insulation. You may also need new joists. With these materials in hand, follow these steps to soundproof your new ceiling:

  1. Attach the hat channels across the joists about 16 inches apart.
  2. With the hat channels attached, slip in your soundproofing material above the joists. Soundproofing material will add weight, so you may wish to add additional joists for support.
  3. Once the soundproofing material is in, add two layers of drywall.

If you’re soundproofing a new ceiling, you can find everything you need for the process by ordering Soundproof Cow New Ceiling Soundproofing Assemblies online.

Soundproofing an Existing Ceiling vs a new Ceiling

How Do You Soundproof an Existing Ceiling Without Removing Drywall?

If you’re willing to tear up your existing ceiling, you can follow the same procedure as for a new ceiling soundproofing installation. If you already have a ceiling you don’t want to remove, you’ll have to get creative — and maybe build a second ceiling. Here are a few ways you can soundproof an existing ceiling without tearing up drywall.

1. Install a Drop Ceiling

The surest way to soundproof a ceiling without tearing it apart is to add a second ceiling below the first. This way, you’ll be able to incorporate soundproofing insulation as if you were installing a brand new ceiling. Dropping your ceiling is a manageable project — attach the hat channels to the existing ceiling, then proceed with the procedure as outlined above. The effect will be the same, but you’ll have a slightly lower ceiling.

You can find all the materials you need to soundproof an existing ceiling by ordering Soundproof Cow Existing Ceiling Soundproofing Assemblies here. Just keep in mind that your ceiling should be at least 7.5 feet tall after the drop.

2. Hang Curtains From the Ceiling

To complement your drop ceiling or to make do with your room’s current ceiling, hang some curtains from above. The thicker, the better. Try thick blankets, carpets or even old mattress pads if you’re not too worried about the look. Ceilings are generally hard and flat, so anything you can do to produce a soft, irregular surface will prevent noise from escaping.

3. Add Some Decorations

Carpets, quilts, curtains and other soft decorations are a quick, cost-effective way to soundproof your room with the current infrastructure intact. These additions you already have lying around the house provide a greater amount of absorptive surface area that will trap sound. Even paintings will mitigate airborne noise more effectively than bare walls.

4. Use Furnishing to Your Advantage

If you want to keep sound in, fill your room with fluffy, comfy furniture. The more irregular and soft surfaces for sound to bump into, the better. Incorporating dressers, drawers, plants and other furnishings that complete your room aesthetically will provide sonic benefits, too. The more surfaces you have in your room, the fewer pathways airborne sound will have to escape.

5. Implement Soundproofing Materials

From acoustic foam to soundproofing barriers and hanging baffles, intentionally crafted soundproofing materials will seal your room and look professional. Soundproof Cow carries all the materials you need to limit the amount of noise that enters or exits your room.

6. Soundproof the Floor Above

If possible, consider installing soundproofing material into the floor above your room. Products like Impact Barrier QT Flooring Underlayment will prevent airborne noise from leaking into the room upstairs while limiting the effects of impact noise on your space.
