In case you haven't heard for yourself, noise comlaints in New York City are peaking in recent years. According to the Office NYC State Comptroller report, New York City received over 610,000 noise complaints in 2024, marking a 19% increase from the previous year. One solution to the problem? Soundproofing your apartment.

But drowning out the sounds of sirens, jackhammers, and thumping bass isn’t the only reason you might choose to soundproof your living space. Maybe you’re tired of hearing your neighbors’ conversations through thin walls. Or maybe you want to be a good neighbor and avoid keeping people awake with your late-night lifestyle, your children and pets, or a remodeling project.

Whatever your reasons, soundproofing your home doesn’t need to be a stressful undertaking if you take the proper precautions.

[#1]How to Block Out the Noise[#1]

When soundproofing a NYC apartment, the first step is to discover, why?

For example, do you entertain large groups of friends often? Do you enjoy listening to music or watching movies with state-of-the-art equipment and surround sound? Do you have children or pets, or do you plan to add to your family? If you work from home, do you conduct confidential calls in which you discuss sensitive information?

A reliable full-service contractor will ask these questions while noting specific site conditions. Plaster, sheetrock, concrete ceilings, wood frames, and more can all affect the soundproofing process. There’s no off-the-shelf or one-size-fits-all solution to soundproofing a condo or apartment, so choose a contractor that gets to know your project first.

If soundproofing is required for any of our full-home design & build jobs, we provide clients with a variety of options for soundproofing an apartment ceiling in Manhattan, even if it’s concrete or soundproofing hardwood floors in a Brooklyn condo. We recommend applications based on each project’s unique context, character, and needs. Some of our most common recommendations include the following elements:

[#2]Decoupled Ceilings: A Soundproofing Solution for Loft Living[#2]

In lofts with high ceilings and minimal separation between units, impact noise—like footsteps, dogs running, or kids playing—can travel through floors and beams, making ordinary insulation ineffective. To combat this, we install a decoupled ceiling, a system borrowed from professional sound studios. A separate ceiling frame is suspended below the neighbor’s subfloor, often including a hat channel, rubber membranes, acoustic insulation, and mass-loaded vinyl. Layers of drywall, paired with Green Glue, further attenuate sound. The result is a dramatic reduction in both impact and airborne noise, letting residents enjoy peace and quiet even in dense, active buildings. See below as Avi explains the process live from our Brooklyn renovation at 85 North 3rd - a Williamsburg soaring condo with 14' ceilings.

[#3]Sound attenuation layers for new flooring[#3]

Most NYC condo and co-op boards mandate that when residents install new floors, they install a sound attenuating layer along with it. The layer rests between the wood floor and the subfloor, and it greatly reduces the sound and vibrations that would otherwise filter through to neighboring condos or co-ops. Because it’s often a requirement, this step is also one of the most common soundproofing applications we recommend.

[#4]Blanket insulation with double sheetrock[#4]

Another strategy we often recommend is to apply blanket insulation on the studs inside of walls, along with double sheetrock. Though this isn’t quite an off-the-shelf process, it’s the closest you’re going to get. It’s the most basic way to soundproof the walls of an apartment, but it does provide partial sound absorption. See Avi explain how we installed double sheetrock at the same condo renovation in Williamsburg as above - specifically designed to keep the peace by minimizing noise from neighboring units.

Soundproof sheetrock

Soundproof sheetrock is more expensive than regular sheetrock, but it’s a much better option for anyone looking for a serious soundproofing solution. QuietRock offers two-way soundproofing and is the material we typically choose for our residential renovations that require soundproofing.

Soundproof paint

Though relatively new, soundproof paint is already largely used in commercial settings like hotel rooms. SoundGuard isn’t as effective as soundproof sheetrock, but it’s estimated to reduce noise by about 30 percent, which makes it a better option for individual rooms instead of an entire apartment.

[#5]Acoustical duct wrap for HVAC systems[#5]

The noise from older central heating and air systems can be a constant nuisance, but acoustical duct wrap can be an excellent choice for eliminating it. Wrapping the air ducts reduces the sound and vibration of the air traveling through them and reduces the sound made by the air handlers.

[#6]Acoustic sound panels and bass traps for special applications[#6]

We also recommend special applications, such as Auralex sound panels and bass traps, for optimal two-way soundproofing. They’re often used in recording studios, but they come in several decorative options for those who enjoy loud music or being fully immersed in movies. That way, you can minimize the sound that escapes from your living space without sacrificing your style.

A lot of cities have a problem with noise, but with a population of 8.55 million people sharing about 778 square miles of land, New York City’s noise problem is notorious. If soundproofing is essential to your upcoming, full-scale NYC home renovation, our dedicated and experienced design-build team will be able to help you find solace in your dream home and block out the noise for good.

[#7]FAQ About NYC Apartment Soundproofing[#7]

How Much Does It Cost To Soundproof A NYC Apartment?

Soundproofing cost depends on scope and method. As an addition to a full renovation, soundproof sheetrock like QuietRock typically adds $5 to $15 per square foot of wall surface over standard sheetrock. Decoupled ceilings run $20 to $50 per square foot installed. Sound attenuation layers under new flooring add $2 to $6 per square foot. Acoustic panels and bass traps for media rooms range from $1,500 to $10,000 depending on coverage. Soundproofing is most cost-effective when included in a full-scope renovation while walls and ceilings are already open, rather than retrofit after the fact.

Do NYC Co-Ops And Condos Require Soundproofing When Installing New Floors?

Yes, most NYC co-op and condo boards require a sound attenuating layer installed between the wood floor and subfloor when residents install new flooring. The requirement protects neighboring units below from impact noise transmission. Building rules vary on the specific product or thickness required, so confirm requirements with the managing agent before specifying flooring materials.

Can I Soundproof My Apartment Without A Full Renovation?

Some soundproofing methods work as standalone applications without opening walls. Acoustic sound panels, bass traps, and soundproof paint can all be installed post-renovation. Acoustic curtains, weatherstripping on doors, and area rugs with thick underlayment also reduce noise without construction. The most effective soundproofing methods, including decoupled ceilings, soundproof sheetrock, and blanket insulation, require walls or ceilings to be opened, which makes them best suited to scheduled renovations.

Do I Need Board Approval To Soundproof My Apartment?

Soundproofing scope that touches structural elements, ceilings, or floors typically requires the same board approval process as any renovation in NYC co-ops and most condos. Standalone surface treatments like acoustic panels or soundproof paint generally do not require approval. Decoupled ceilings, full wall replacement with soundproof sheetrock, and floor work all require alteration agreements, contractor insurance, and adherence to building work-hour restrictions.

What Is The Difference Between Impact Noise And Airborne Noise?

Impact noise transmits through building structure when something physically contacts a surface, like footsteps, dropped objects, or dog claws on a floor above. Airborne noise travels through air and structures from sources like voices, music, and television audio. The two require different soundproofing approaches: impact noise is best addressed with decoupled assemblies and floor underlayments, while airborne noise responds to mass and density treatments like soundproof sheetrock and acoustic insulation.

Is Soundproof Sheetrock Worth The Extra Cost Over Standard Sheetrock?

For serious soundproofing, yes. Soundproof sheetrock like QuietRock offers two-way sound reduction (blocking sound from entering and from escaping) and significantly outperforms standard sheetrock for the same wall thickness. The cost premium is typically $5 to $15 per square foot over standard drywall. For shared walls with neighboring units, bedrooms requiring sleep quality, or any room where serious noise control matters, the cost difference is worth it. For interior walls between rooms of the same unit, standard sheetrock with blanket insulation is often sufficient.

Will Soundproofing Lower My Ceiling Height?

Some soundproofing methods reduce ceiling height. Decoupled ceiling assemblies typically lower ceilings by 3 to 6 inches due to the suspended frame, acoustic insulation, rubber membranes, and double drywall layers. In pre-war apartments with high original ceilings, this is often acceptable. In low-ceiling post-war apartments, alternative approaches like high-mass single-layer treatments or focusing on wall soundproofing instead may be preferable. Soundproof sheetrock and wall insulation do not affect ceiling height.

Can Pre-War NYC Apartments Be Effectively Soundproofed?

Yes. Pre-war NYC apartments respond well to soundproofing during renovation because plaster walls are typically opened for electrical and plumbing updates anyway. The walls-open phase is the right time to add blanket insulation, soundproof sheetrock, and acoustic treatments without additional demolition cost. Decoupled ceilings work especially well in pre-war buildings with high ceilings that can absorb the height reduction. Older plaster walls actually have decent inherent mass for blocking airborne noise compared to modern hollow-core construction.
