They are the decorative version of sound insulation.

For Sound Absorbing

(Auralex Studiofoam Wedges) or Acoustic Foam

This product from Auralex, a well-reputed acoustic foam brand is one of their best products and is an excellent sound absorber. It comes in numerous shapes and sizes and is an ideal choice if you are a musician, recording artist, podcaster or home theatre lover.

With NRC rating sitting at 0.8, the anechoic wedge has the ability to cut down on reverberation drastically, flutter and slap considerably and is to be fitted high on your room’s walls. They are available in colors of charcoal and burgundy and are applicable for small to medium-sized rooms.

Sound Absorbing Foam (Pro Studio Acoustic Tiles)

This product, unlike Auralex, offers a range of colors, like blue, red, teal and purple, to contrast with charcoal. Manufactured in the USA from premium quality acoustic foam, these wedges are ideally installed in walls with problem of noise reflection, or as ceiling tiles to reduce echoes and reverberations. Alongside soundproofing, their bright colors are helpful in decorating your interiors, such as theatre rooms, voice booths or studios, and gaming rooms.

Acoustic Panels (ATS Acoustics)

Acoustic panels are ideal for rooms where the wedge and pyramid foam is not visually appealing. These framed panels, with a wooden finish, resemble a decoration or a picture frame more than a sound proofing panel. With an NRC rating of 1.0, these ATS panels are sold as single panels, and its best recommended buying them in bulk in order to save on shipping costs.

For those rooms where acoustic foams don’t quite do it justice visually, acoustic panels do the job perfectly well.

These sleek panels are made with a solid wood frame and Roxul ABF mineral wool, with a finishing of jute-made fabric cover, adding an element of style and elegance. Available in colors, ranging from beige, to black to burgundy to ivory, these panels are to be hung on the walls next to the hardware.

Soundproofing Insulation

Mineral Wool (Rockwool Rockboard)

Rockboard consists of  strong, fire-resistant mineral wool insulation, which provides one of the best soundproofing for walls. Used for both acoustic and thermal insulation, this product is used in both residential and commercial buildings. With an NRC rating of 0.8-1.1, based on thickness, Rockwool Rockboard serves as a highly effective sound insulation board for homes and buildings.

Made of natural and organic mineral wool, it gives you the opportunity to earn LEED points for its installation. Apart from being compact, ductile and malleable, it is also moisture and fire-resistant up to 250F.

But that’s not all…

You can also make your own acoustic panels and bass traps using Rockwool. All your work is to build a wooden frame, fit the Rockwool boards and give it a nice fabric finishing.

Rockboard also has an alternative in Rockwool Safe’N’Sound as a high-quality soundproofing material for walls and ceilings. It can be fitted into the stud wall cavities easily and tightly, owing to its flexibility and softness. However, unlike other soundproofing wall insulations, this is not available online.

Mass Loaded Vinyl (Dynamat Xtreme)

Essentially applied as a layer of insulation in soundproofing walls, floors and ceilings, Mass Loaded Vinyl or MLV is a flexible, highly dense membrane sold by various brands such as Dynamat Xtreme, and Acoustiblok. They are sold in bulk rolls of sheets. Their flexibility and adhesive abilities make them an effective sound insulator for deadening unwanted, annoying outdoor sounds.

Sound Deadening Paint (Acousticoat Paint)

This effective soundproofing material has often been regarded as a myth but let’s examine if this is true or not. Soundproof paints can be rolled and sprayed on the walls, forming a thick insulating layer to keep noise out. Painting them on walls creates thin layers, compared to spraying, which ensures a thicker coating of the paint to be more useful in noise reduction.

Although soundproof paints might not be the magical solution to all of your insulation problems, it is certainly claimed to provide a 3-7 STC point increase after using this product.

7. Drywall

Also known as plasterboard, wallboard or gypsum board, this is an excellent and cost-effective alternative, which provides one of the best soundproofing for walls. Like a sheet rock on steroids, sound proof drywall contains layers of gypsum board along with layers of steel.

This increases its mass and density, and in turn, blocks the sound. Heavier mass and density is highly beneficial in improving STC ratings, with regards to soundproofing walls. You can also go for damped drywall, which incorporates an additional sound damping layer and has great sound insulation properties.

Damping Compound (Green Glue)

Green Glue Noiseproofing Compund is a familiar name in the market today, and is used as a sound dampening material for the soundproofing of walls. With packaging designed as style dispensing tubes, making it easier to be applied, these are available as Green Glue Compound and Green Glue Sealant. When applied between drywall layers, it absorbs sound vibrations and reduces noise. Green Glue Sealant is used for sealing numerous places like holes, seams and gaps in walls and ceilings. The sealant acts as a noise barrier, preventing sound leakage.


So the bottom line is, sound proofing walls are an essential step in home planning, which must be dealt with at your soonest convenience. The products above are just what you need to ensure that you have a quiet home, uninterrupted and undisturbed by any external noise.
