Is your home filled with excessive noise that drives you crazy?
The most effective soundproof flooring uses double layers to block noise transfer. But foam underlay upgrades also dampen noise at lower cost.
Let’s dive into ranking flooring for noise reduction to find your best fit.
Types of Flooring for Soundproofing
When it comes to soundproofing a room, the flooring can make a major difference in how much noise passes through.
There are several flooring options specifically designed to reduce noise transfer and dampen sound.
In this article, we will overview the main types of flooring to consider for sound insulation and rank them by effectiveness.
1. Double Layer Flooring
Double layer flooring involves installing two layers of flooring with a decoupling layer in between. This air gap acts as a buffer that dampens noise and blocks transfer of vibrations.
Double layer systems are the most effective option for soundproofing floors, capable of reducing noise by 25 decibels or more.
There are a few different ways to create a double layer floor. One method is to install a floating subfloor over the existing floor, using foam or cork underlayment.
Next, your choice of floor covering like laminate or engineered wood goes on top. The underlayment dampens noise while the two layers prevent noise transfer.
Another approach is to use staggered studs underneath, creating separation between the subfloor and joists. Batt insulation placed in the stud bays adds mass and absorption.
Some double layer systems come with specialized acoustic clips or channels to decouple the two floors. These enhance noise blocking by preventing transfer of vibrations.
Overall, double layer flooring blocks airborne and impact sound transmission better than any other option.
With the right materials and proper installation, noise reduction can exceed 25 decibels.
This level of soundproofing performance makes double layer systems ideal for multifamily housing, basements, home theaters and more.
2. Laminate/Vinyl with Foam Underlayment
Laminate and vinyl flooring already provide some noise insulation on their own.
But adding a high-quality foam underlayment takes the sound dampening to the next level. With underlayment, these flooring types can reduce airborne noise by 18-25 decibels.
The underlayment is the key element providing noise blocking. Look for acoustic foam options made from recycled rubber, cork or Virgin SBR formulations.
The density rating indicates sound dampening capability – the higher the number, the better. Some premium underlayments have both noise blocking and anti-vibration features.
On top of the underlayment goes your laminate or vinyl planks. Either option gives a further noise barrier thanks to the floors’ rigid construction.
Laminate utilizes fused layers while vinyl has a resilient core. Combined with foam underlay, walking noise and other impact sound transfer is significantly decreased.
Laminate or vinyl flooring takes well to foam underpadding. Installation is simple compared to other soundproofing floors, making DIY friendly.
As long as the correct underlay thickness and density is used, noise reduction of 18-25 decibels can be achieved. This matches insulation levels of far pricier flooring but at a more budget-friendly cost.
3. Rubber Flooring
Known for its durability, rubber flooring has excellent noise dampening abilities as well. By nature, rubber blocks and absorbs noise rather than transferring vibrations.
As a result, rubber floors reduce airborne and impact noise by 14-21 decibels on average.
There are a few types of rubber flooring to consider. Rolled rubber sheeting provides seamless coverage, often used for basement subfloors.
Interlocking rubber tiles allow flexible installation patterns. These are commonly seen in gyms and fitness centers. Finally, poured rubber floors offer heavy-duty acoustic insulation.
In all rubber flooring, density and thickness play a role in sound dampening. Commercial rubber floors tend to be thicker and denser, with the capacity to reduce noise up to 21 decibels.
Home rubber tiles are thinner but still provide decent sound insulation around 14 decibels.
Rubber’s natural dampening properties give it an advantage over other hard surfaces. As footsteps and other impact noise hit the floor, the rubber absorbs vibrations rather than passing them on.
This prevents echoing and transmission to lower levels. Rubber flooring works equally well against airborne noise like voices.
Overall an effective solution for multi-level and commercial buildings that demand acoustic control.
4. Cork Flooring
Known for its eco-friendly profile, cork flooring offers moderate soundproofing as a bonus feature. Cork naturally absorbs and blocks noise due to its honeycomb cellular structure.
Quiet Walk cork floors reduce both airborne and impact sound transmission by 13-15 decibels on average.
The resilient honeycomb construction gives cork both absorption and barrier properties. Noise enters the tiny air pockets, dissipating the vibrations so less gets transmitted.
Cork also forms a barrier preventing noise transfer to the subfloor. Combine these qualities and walking, voices, appliances and other impact noise are noticeably reduced.
Cork flooring comes in both tile and plank formats to fit various project needs. Tiles offer flexible installation patterns, working well for entryways, laundry rooms and basements.
Floating cork planks better suit living spaces like bedrooms and dining rooms. For improved acoustic control, opt for thicker profile tiles or planks wherever possible.
While not the most heavy-duty soundproof option, cork floors notably dampen noise in their own right.
This makes them suitable for condos, apartments and multi-level homes where noise transfer issues are moderate.
Eco-minded homeowners often choose cork specifically for environmental reasons while benefiting from built-in sound insulation.
5. Carpet
Carpet has long been valued for its ability to soften impact noise and reduce echos. Heavy foot traffic, moving furniture and even rambunctious kids make less noise on carpeted floors.
While carpet may not achieve the highest noise reduction levels, it still effectively absorbs impact and airborne sound.
The key to carpet’s noise dampening abilities lies in the fibers and padding underneath. Fibers vary in thickness and density, fine delicate strands versus tight low pile types.
Thicker shag carpets works best for absorbing noises reflected across hard surfaces. The dense cushioning under carpets also dampens impact noise from footsteps and dropped objects.
Overall carpeting reduces airborne noise like speech and television sound by 10-20 decibels. For impact noise such as footsteps, noise reduction ranges 15-25 decibels.
Wool and nylon carpets rate on the higher end thanks to more sound dampening mass.ngram level loop pile carpets offer a budget floor noise solution, still lowering decibel levels 10-15 range on average.
In spaces prone to echoing noise like hallways or tiled kitchens, a simple rug can soak up excessive sound.
Area and wall to wall carpeting helps contain noise between rooms with doors closed.
While carpeting may not match rubber and double layers overall, it conveniently reduces floor noise across many living spaces.
How Do The Different Flooring Rank by Soundproofing Effectiveness?
After covering the main types of flooring with noise dampening capacities, how do they compare for overall soundproofing? Here we rank the options from most to least effective based on decibel reduction levels.
1. Double Layer Flooring
Taking the top spot for maximum noise blocking are double layer floor systems with 25+ decibel reduction on average.
Creating separation between subfloor and floor covering provides isolation of impact and airborne sound.
Pairing the air gap or staggered studs with absorptive insulation optimizes acoustic control results.
