What is Acoustic Melamine Foam?

You are currently viewing What is Acoustic Melamine Foam?

Have you ever wondered how recording studios block out external noise or why your dishwasher is so quiet compared to older models?

The secret lies in a porous sound-absorbing material called melamine foam.

Let’s dive in to understand precisely what melamine foam is and why its acoustic properties make it the gold standard for soundproofing.

What is Melamine Foam?

Melamine foam with a lightweight and porous structure, ideal for sound absorption

Melamine foam is a foam-like material made from melamine resin.

It has a very lightweight and porous structure that makes it suitable for sound absorption and noise control applications.

The open-cell design allows sound waves to enter the foam rather than bounce off it, enabling effective damping across a range of frequencies.

Originally developed as insulation and soundproofing material in the 1960s, melamine foam has become popular in recent years for do-it-yourself sound treatment.

Acoustic Properties of Melamine Foam

The defining characteristic of melamine foam that makes it so useful for acoustics is its sound absorbing abilities.

Some key properties include:

Sound Absorption

The open cell structure of melamine foam absorbs sound waves rather than reflecting them.

When sound enters the porous foam, the energy gets dispersed within the foam’s matrix.

This is more effective at preventing echo and reverberation than solid surfaces that just reflect the sound waves.

Noise Reduction 

Thanks to its excellent sound absorption, melamine foam is very effective at reducing ambient noise in offices, studios, appliances, and other environments.

Panels made from melamine foam can be installed on walls and ceilings to dampen and muffle noises caused by people, equipment, road noise, etc.

The foam transforms noisy spaces into quieter, calmer spaces by diminishing distracting background noise pollution.

Sound Dampening

Melamine foam prevents the buildup of unwanted reverberation and echo within a room.

Unwanted reverberation can make speech and music sound blurry.

The porous foam absorbs the excess sound energy to dry up the reverb, allowing better clarity and intelligibility.

This also reduces listening fatigue.

Range of Sound Absorption

While melamine foam absorbs sounds across the entire frequency spectrum, it performs particularly well in the mid and high frequency ranges.

This means it absorbs the frequencies that dominate human speech and many musical instruments very efficiently.

The foam dampens annoying high-pitched sounds quite effectively.

Uses as an Acoustic Material

The useful acoustic properties of melamine foam make it popular for studio soundproofing, appliance noise reduction, office privacy, and automotive sound dampening:

Studio Soundproofing 

In professional audio and video production studios, melamine foam panels help absorb ambient noise and control acoustic reverberation issues.

Panels placed strategically on walls, portable baffles around microphones, and bass traps in corners all help optimize the listening environment.

Appliance Noise Reduction

Manufacturers use melamine foam in appliances like dishwashers, refrigerators, and washing machines to reduce operational noise.

The foam dampens vibrations and absorbs fan noise to ensure quiet performance.

This prevents appliances from being disruptive at home or in commercial spaces like offices and hotels.

Office Noise Control 

Installing melamine foam panels on office and cubicle walls/ceilings helps mute conversations, keyboard clatter, phone noise, and other distractions.

This fosters better focus, privacy, and reduced anxiety in open office plans.

It also reduces noise pollution bleed issues between adjacent conference rooms or offices. 

Automotive Applications

Melamine foam adhesive pads attached to car doors, firewalls, trunk, wheel wells and other cavities help absorb road and engine noise for a quieter ride.

Aftermarket automotive insulation kits often include melamine foam for its lightweight, effective noise damping abilities.

Comparisons to Other Sound Absorbers

While all sound absorbing materials work by converting acoustic energy into heat as sound enters their porous matrices, melamine foam has some advantages over other common options:   

More Effective than Fiberglass or Mineral Wool

The open cell structure of melamine foam provides better sound absorption across a wider range of frequencies compared to materials like fiberglass, rockwool, or mineral wool insulation.

It also lasts longer without sagging issues.

Cheaper and Easier to Work With Than Acoustic Tiles/Foams 

Professionally installed acoustic ceiling tiles, Pyramid or Wedgie foams can be expensive.

Melamine foam panels are affordable and easy to cut and arrange even for DIYers without special tools.

The foam is also safer to handle than itchy fiberglass.

Advantages Over Tapestries

While thick fabric wall hangings absorb some sound, they lack robust noise blocking abilities.

Melamine foam is tuned specifically for superior audio absorption and works better than purely decorative fabrics.

Pros of Using Melamine Foam

There are many benefits that make melamine foam a compelling acoustic treatment option whether used by professional studios or regular consumers:


Melamine foam is cheaper compared to materials like acoustic ceiling tiles or dense studio foam wedges.

This enables excellent sound treatment on a budget.


Weighing only 9-20kg/m3, melamine foam is extremely lightweight.

This simplifies installation using basic hardware or adhesives.

Carrying and moving panels is easy too.

Ease of Installation

The foam can be installed on any sound reflecting surface using simple adhesive, Velcro, pins, or tape without special tools or skills.

It is also easy to cut to size using just a knife.

Customization and Versatility

Melamine foam can be manufactured in almost any thickness, density, shape and size.

It can be used for spot sound absorption or cover entire walls/ceilings.

The foam conforms well to curved or irregular surfaces too.


Properly maintained melamine foam retains its porous structure and acoustic properties for years despite frequent compression.

It does not wear out or crumble easily like other sound absorbing foams.

Cons of Using Melamine Foam

However, there are some downsides to melamine foam to consider as well:

Not Effective at Blocking Sound

While melamine foam absorbs sound very effectively, it does not block sound transmission.

It needs to be paired with mass loaded vinyl or drywall to contain noises within a room.

Dust Build Up

Melamine is prone to catching floating dust, lint and fibers that settle within the porous structure over time.

This may necessitate occasional cleaning and vacuuming to maintain acoustic performance.


The base melamine resin is flammable when directly exposed to flames or extreme heat.

As such, the foam may pose fire risks if improperly installed near strong ignition sources.

Alternatives to Melamine Foam  

Comparison of alternatives to melamine foam: polyester acoustic panels, mineral wool, and cotton batt insulation

There are a few alternatives to melamine foam worth considering for certain acoustic applications:

Polyester Acoustic Panels

Fiberglass-free polyester panels offer great sound absorption that rivals melamine foam.

Polyester is also more durable and fire resistant, making it a cost effective melamine alternative. 

Mineral Wool

Mineral wool like rockwool or fiberglass insulation also provides decent broadband sound absorption.

However, melamine foam is generally easier to work with and lasts longer without sagging issues.

Cotton Batt Insulation

Densely packed cotton insulation bats can make an eco-friendly sound absorber, albeit less effectively than acoustic-specific melamine or polyester foams at lower price points.
