What You'll Learn (and Why It Matters)

Ceilings are one of the most common paths for noise to travel between rooms and floors. Footsteps, voices, music, and TV noise easily transfer through ceiling assemblies that lack isolation, mass, and airtight construction. This guide explains how to soundproof a ceiling by addressing both airborne and impact noise using proven, building-assembly–based solutions.

By the End of This Guide, You’ll Be Able To:

Identify your ceiling noise problem as airborne or impact-based
Understand why ceilings transmit sound so easily
Decide whether to treat the ceiling below or the floor above
Follow correct installation steps for ceiling- and floor-side soundproofing
Choose the most effective approach for your situation

Before You Start: Identify the Type of Noise

Before choosing a solution, determine whether you’re dealing with airborne noise or impact noise. Airborne noise includes voices, music, televisions, and barking dogs. Impact noise includes footsteps, dropped objects, and furniture movement. Most ceiling noise problems involve both, but impact noise is usually the issue. Identifying the noise type helps you avoid solutions that won’t address the real problem.

In addition, you’ll need to decide which side of the floor–ceiling assembly to treat. Some solutions are applied from the ceiling below, while others work by treating the floor above. You need to pick which one based on which is accessible to you.

We’re going to walk through those steps for soundproofing a new ceiling. If you are soundproofing an existing ceiling without removing drywall, you’ll want to jump over to our guide on the topic.

Step-by-Step: How to Soundproof a Ceiling From the Ceiling Side (Recommended When Accessible)

This approach is used when you have access to the ceiling below and want to reduce noise coming from the room above.

Step 1: Attach RSIC-1 Clips to the Ceiling Joists

Fasten RSIC-1® Resilient Sound Isolation Clips directly to the ceiling joists, following proper spacing and layout guidelines. The clips create a flexible connection point that limits vibration transfer from the structure above.

Accurate clip placement is critical. Clips should be installed in straight rows so the channel system can engage evenly across the ceiling.

Step 2: Snap 25-Gauge Hat Channel Into the Clips

Snap 25-gauge hemmed-edge detail hat channel into the RSIC-1 clips. The channel should run perpendicular to the joists and remain continuous across the room wherever possible.

The hat channel supports the new ceiling surface while maintaining isolation from the framing.

Step 3: Screw Drywall Into the Hat Channel Only

Install drywall by screwing it into the hat channel. If additional sound blocking is needed for airborne noise only, a second layer of drywall may be added. This increases mass but does not significantly reduce footsteps or other impact noise.

Step 4: Seal the Perimeter and All Penetrations

Leave a small gap around the perimeter where the ceiling meets the walls. Seal this gap, along with all penetrations for lights or fixtures, using acoustical sealant caulk.

Airtight sealing is essential—unsealed gaps allow sound to bypass even the best isolation system.

Key Tip

Mass Loaded Vinyl can be used to add mass for airborne noise reduction, but it does not address impact noise and is cumbersome to install overhead. For this reason, it is not the recommended ceiling-side solution and should only be considered in limited airborne-noise-only scenarios.

Step-by-Step: How to Soundproof a Ceiling From the Floor Side (Best for Impact Noise)

This approach is used when treating the ceiling below is not practical or when impact noise is the primary concern. Floor noise reduction can be achieved by following a few simple steps, but being careful to pay attention to detail.

Step 1: Choose the Correct Rubber Underlayment Thickness

Select a rubber underlayment thickness appropriate for the finished floor type. For most flooring types, you can use any thickness without any issues. However, with tile floors, you either need to use a 2mm thick underlayment or install a plywood layer over your chosen thickness.

Step 2: Install Underlayment With 100% Coverage Over the Subfloor

Lay UnderBlock™ Rubber Soundproofing Underlayment across the entire subfloor with full coverage. Seams should be tightly butted—not overlapped—to maintain a continuous isolation layer.

Key Tip

Partial coverage will significantly reduce effectiveness.

Step 3: Add a Plywood Layer if Required by the Finished Floor (Optional)

For tile floors or flooring systems that require nailing, a plywood layer may be installed over the rubber underlayment. This plywood layer can be glued down where appropriate, depending on flooring requirements. This step protects the underlayment and provides a stable base for the finished floor.

Step 4: Install the Finished Floor With Isolation Gaps

Install the finished flooring while maintaining a 1/8-inch gap around the perimeter of the room and around any penetrations. These gaps prevent rigid contact with walls and structural elements.

Once the floor is installed, perimeter gaps should be sealed with acoustical sealant caulk.

Key Tip

Never nail or screw through rubber underlayment into the subfloor. Penetrating the underlayment creates a rigid connection that defeats its ability to isolate impact noise.

FAQ

What’s the most effective way to reduce footsteps from above?

Decoupling the ceiling with RSIC-1 clips or treating the floor above with rubber underlayment.

Does adding drywall help with impact noise?

No. Additional drywall improves airborne noise only.

Why is sealing so important?

Sound escapes through gaps just like air, bypassing heavier materials. Also, having non-hardening caulk prevents walls from transmitting structural noise into your ceiling and vice versa.

Can floor and ceiling treatments be combined?

Yes. Treating both sides of the assembly provides the highest performance.

Is ceiling-side soundproofing always possible?

Not always. Ceiling height, access, and mechanical obstructions can limit options.

How much does it cost to soundproof a ceiling?

That will depend heavily on what method you choose and how large your ceiling is. Read our guide on the cost of soundproofing a ceiling for a better look.
