How to Soundproof a Room in an Apartment?

How would it feel if something pierced through your skin and entered inside, disrupting all of your organs and their functions? Sounds gruesome and horrifying, right? That’s exactly what the outside noise does to your apartment rooms.

It enters uninvited through different outlets and surfaces, disrupting the whole interior atmosphere and most importantly, your inner peace.

Whether it is the noise from traffic, your annoying neighbors, construction work, or just the constant buzzing of gadgets and devices, noise from inside or outside can ruin your home environment completely, thereby disturbing your sleep and hampering your productivity.

This is where soundproofing comes to rescue.

Below, we show you how to soundproof a room in an apartment to cancel out all noise— both internal or external. 

How to Soundproof a Room in an Apartment?

1. Eliminating the Echo in Your Apartment

Before coming to conclusions, it is important to first locate the source of noise. It often happens that the noise is actually coming from inside while we keep looking for all external solutions.

This internal noise is what gives rise to echoes and reverberations across the room. Solution for this works out to be quite simple as well. Make sure your walls, ceilings, furniture and floors are all well-covered in order to prevent the noise from bouncing off those hard surfaces and back to your ears, in the form of an echo.

Eliminating the Echo in Your Apartment

To do this, invest in some plush and heavy-duty rugs for floors, furniture blankets and covers which can significantly reduce the noise through sound absorption.

You can also adorn your walls with some wall paintings and wooden hangings to reduce the echo effect.

2. Find the Holes and Seal Them

These holes and spaces are the weak links and silent enemies of your room’s silence. Search for them thoroughly throughout your room, especially on the walls and cables.

If you find any of those leave everything aside and seal them first. This can be done using various materials such as fiberglass, which is a perfect sealant. Fiberglass is a cloth with a web-like structure that holds the sound inside its threads. After it is applied, the fiberglass seals in all the small crevices, thereby preventing the unpleasant noise to pass through.

Although it insulates heat just as well, the fiberglass is ideally used as a sound-absorbing substance.

3. Soundproofing the Windows

Soundproof Curtains: These curtains are perfect for sound insulation, having made from insulation material which doesn’t only blocks sound but also heat and UV rays.

Moreover, they come in a wide range of attractive colors and affordable prices, which goes to enhance your home décor without burning a hole in your pocket.

Caulking and Sealing: For any gaps and spaces in the window frame, acoustic caulking or using soundproofing sealants like Green Glue are very effective for noise reduction. Green Glue is easily available in online stores like Amazon and is one of the most sought-after soundproofing products.

Don’t Miss out the Windows

Window Inserts: These are great energy-saving products, made from tough and sturdy soundproofing materials such as thick glass and transparent acrylic. They are attached to the existing windows to add a layer of sound proofing, creating an air-seal which blocks and absorbs the external noise from passing through.

Window Panels: Inserted inside the window, these panels are made of special, sound-absorbing material with complete noise-cancellation properties.

The most commonly used are the acoustic home panels for rooms and studios which are very effective in deadening out noise completely. However, they come with one small setback – they block your view from the window.

 So, if you are looking for a permanent soundproofing solution and don’t mind compromising on your window view, this is the perfect product for you.

4. Thin Walls, the Most Common Problem

One of the major gateways of noise entering your room is the paper thin walls, which are mostly made of sound conducting materials like wood and brick. Moreover, if you share a common wall with your neighbor, you are most likely to be troubled with noise originating from their apartment at all times.

Hence, if you want to successfully soundproof your apartment room, soundproofing the walls is a must.

Thin Walls, the Most Common Problem

Adjusting your bookshelves and wardrobes against the wall is an easy and cheap method of curbing the noise. However, if you are looking for a more effective and compact solution opt for wall foam panels or drywall, which are installed to insulate and trap the noise from entering the room. You can also adopt decoupling methods by creating a separate wall layer to obstruct the path of sound.

5. Insulating the Floor and Ceiling

Ceiling Insulation:

All the noises and sounds from your neighbor upstairs, along with sounds of the different ducts and ventilations enter your room through the ceiling.

You could first go talk to your neighbor, suggesting them a solution like carpeting their floors to reduce sound transmission. Just in case that fails, you might have to invest in some proper ceiling insulation. If you are wondering – how do you soundproof an apartment ceiling, the answer is relatively simple.

As in case of windows, installing acoustic foam panels come in very handy in terms of providing sound insulation.

Available in a combination of designs and colors, these add an element of style and elegance to your apartment room.

Soundproofing Mats

Floor Insulation: Floors are mostly made of wood and are contributors to the echo effect. Those footsteps in the hallway and corridors every time someone passes through can be prominently heard through the floors and cause a very disturbing effect inside your room.

In order to prevent this intrusion of peace and privacy, floor insulation is necessary. You can soundproof the apartment floor using heavy duty rugs and thick carpets in places where maximum noise is heard. Else, installing soundproof tiles is another effective and permanent method of providing sound insulation.

6. At Times, Noise from Ventilation Is Too Loud

The ventilation system for your air conditioners and other gadgets contribute heavily to noise conduction. One effective solution for soundproofing the vents is the concept of ‘maze vent’. It is made of materials that absorb sound and capture it within its layers, providing sound insulation to your room.

7. Soundproofing the Doors

Adhesive Weatherstrip Foam Tape: This is made as a rubber tape or plastic lath that can be easily attached to the door as an adhesive, thereby blocking out any noise. It provides protection from thermal leak, noise leakage, bugs and moisture.

Dor Blanket: This is a kind of soundproof blanket for the door, which is one of the cheapest solutions for sound absorption. It can also be used for decorative purposes and is super easy to install.

Soundproofing the Doors

Draft Stopper: This pillow-like soundproofing solution goes underneath your doors, acting like a sound stopper. It is a cheap solution for sound insulation.

If certain situation arises and you need to take drastic measures, going for a soundproof door or an acoustic panel fitting on your door is the way to go.

8. Paint the Walls with Special Sound-Absorbing Paints

Painting your apartment walls with sound-absorbing paints reduces the outside noise significantly. Provide a thick coating of these paints over your walls and watch their heavy and speckled surface absorbs up to 30% and more of sound. This leaves you with a peaceful and noise insulated interior.


The soundproofing methods and solutions mentioned above are cheap and easy to follow. Now that you know how to soundproof a room from outside noise you should get started right away. There’s no denying they give you the privilege of inhabiting a quiet and peaceful home, with a soothing and relaxing atmosphere that is conducive to your health and well being.
