Soundproofing Home Cinema Room

In this blog, we will discuss all the relevant details about soundproofing a home cinema room. We will cover all the procedures and details so that you can effectively accomplish the goal. Also, we will be answering the questions most readers have in their minds so that you get your answers right. So, let’s get started!

According to the latest study from TV manufacturer Hisense, 3.6 million Britons have upgraded their home watching experience in the previous year by purchasing new TVs, sound systems, and projectors. A further 9.2 million households are considering setting up a home theatre.

According to the Entertainment Retailers Association, two-thirds of UK viewers consider film and television to be their preferred form of entertainment, and this, combined with the introduction of extra-large screen televisions, helps to bring the magic of the cinema home. It’s no surprise, then, those early projections show that 2022 will be the most successful year in the history of Home Entertainment. BASE’s Chief Executive, Liz Bales, stated: “Throughout the pandemic, many people preferred entertainment at home as a haven from an uncertain world. Continuing to provide audiences with the material they enjoy is propelling a new, inventive Home Entertainment future.”

How to Soundproof Home Cinema Room?

Soundproofing a home theatre room isn’t as difficult as it may appear. It’s no different than soundproofing any other room in the house. What matters is that the soundproofing solution is appropriate for the type of room being converted, such as whether it is a ground floor room, a detached room, a room with a timber joist floor, or a room with a concrete floor. Another factor to consider is how much height will be lost as a result of soundproofing the ceiling. These are some of the crucial questions to consider before soundproofing a home theatre or theatre room.

If you’re unsure about which soundproofing method is appropriate for your home theatre, always consult an expert. The base frequency emitted by the subwoofers is one of the biggest issues with home cinema room soundproofing since it may readily transfer into the structure of the building and go through walls, through ceilings, and through floors.

When soundproofing a home theatre, there are crucial measures to follow:

  • Build A Room Within A Cinema Room
  • Decoupling the Walls of Home Cinema Room
  • Use Soft Material for Soundproofing 
  • Blocking Air Leaks of Cinema Room
  • Use of Thick Carpets
  • Use of Floor Underlayment
  • Use Soundproof Good Quality Doors
  • Soundproof Windows for Cinema Room
  • Build Bookcases 

Build A Room Within A room

Our go-to solution for loud levels of noise is to build a ‘room within a room with an air gap and a new stud wall,’ which helps to contain airborne sound energy and vibration within the home cinema room space, preventing it from getting into the main structure of the building and being heard elsewhere. The room can be made soundproof with different soundproofing materials like installing acoustic panels on the walls of the room. Use soundproof curtains, for this purpose Lush Décor Blacking Out Light and Soundproof Curtains ,can be used which are quite effective.

Decoupling the wall

The process of making two sides apart such that they vibrate independently of one another is known as wall decoupling. Decoupling is one of the most successful methods for vanishing sound on a single side of one wall while preventing it from going through to the opposite side.

This decoupling can assist us to isolate higher frequencies, but not low frequencies, because the captured lower frequencies will be transmitted to one of the walls by the air inside the hollow.

Green Glue might help to reduce the transfer of low frequencies to the wall. Green glue has the power to transform soundwaves into heat and is particularly excellent in dealing with low-frequency sound energy and reducing sound in the building’s interior.

It’s inexpensive and recommended if you’re having trouble with low noise frequencies.

How to use Green Glue?

This is a three-step procedure for using green glue.

  • On the backside of the second drywall, apply many coats of green glue; preferably, 1-2 tubes should suffice.
  • Now press down this drywall on top of the existing wall, keeping in mind that it will dry in 15 minutes.
  • Attach the second drywall to the existing drywall with screws.

As a result, green sealant can help us damper soundwaves and minimise resonance indirectly and is the most appropriate method for soundproofing existing walls.

Use of Soft Material for Soundproofing

Soft material in a room can absorb the sound waves in a way that we feel the warmth of the cinema room. So, the use of soft blankets, floor rugs, heavy curtains can play role in sound reduction.

Blocking Air Leaks of Cinema Room

The very first thing to check for when soundproofing a wall or ceilings between rooms is air channels. Air channels can be found in places like wall sockets and switchboards, gaps under baseboards, and HVAC vents, in additional doors and windows. Sound travels best in the form of air, thus any holes or openings that allow air to circulate through will also allow sound to enter a room.

Special soundproof source covers, soundproofing putty, fibreglass insulators, or acoustical foam gaskets can be used to seal air leakage at electrical boxes. Air vents, on the other hand, are a little trickier. You can’t conceal vents permanently because they’re necessary for warming your cinema room or flowing fresh air, but if you truly need to have some peace, you can.

How to check air leaks?

To avoid door air leaks, begin by doing the following:

  • Remove the door trim and use acoustical sealant to seal the frame.
  • weatherstrippings should be attached to the surface and edges of the door.
  • Seal the base of the door with a door sweep.
  • Continue to stand within the room door sealed and the lights turned off to inspect for air leaks. If light shines through, there is an air leak through which sound can travel.

Use of Thick Carpets

The use of thick carpets in home cinema rooms will make it denser, thick carpets can absorb more sound helping the floor to be more soundproof, the bare floor will reflect the sound effects around the room causing echo. So, I will suggest using thick sound-absorbing and soundproofing carpets. I would suggest using Sonic Acoustics Non-Slip Soundproof Rug Pad along with heavy soundproof fluffy carpet.

Use of Floor Underlayment

For soundproofing a cinema room, we need to make its floor soundproof via floor underlayment for floating hardwood flooring. It will not only effectively minimize footfall impact sounds, but it also features a barrier that resists moisture, mould, and mildew, working as a sound reduction for hardwood.

The process to do floor underlayment

we can utilize nails, glue, or both to install hardwood floorboards. Nails can bypass the noise to subfloors, thus glueing is a better solution if at all possible. By every mean your room will feel a clear difference in the reduction of noise.

Use Soundproof Good Quality Doors

Home cinema rooms with hollow-core doors, which have a thin outer surface of the wood with plastics or board inside, are generally poor absorbers of the sound, sound may easily penetrate through them. Replacing a lightweight door with a heavy-duty strong door will help block out the noise to the surrounding environment of the rest of the home. So, I would suggest using the heavy thick door for the cinema room.

Soundproof Windows for Cinema Room

Soundproofing a window with a sheet or soundproof curtains can eventually help in making a cinema room more soundproof and, blocking the noise going out into home premises.

Process of soundproofing windows in a cinema room

  • Fill up every gap around the window with Caulk. To limit the amount of indoor/outdoor noise that enters or leaves your cinema room, make sure all holes surrounding your windows are sealed.
  • Construct a Barrier in Front of the Window
  • Hang acoustic curtains
  • Double and triple-coated window panes are the final step of this process.

Build Book Cases

Bookcases, strange as this may seem, can help to keep an area quiet. This is because bookshelves produce mass, which absorbs sound. Just make sure the bookshelf extends from the floor to the ceiling and that the shelves are stocked with magazines and books.



Your home cinema room is a kind of special room where one would like to have his time enjoying movies and stuff with friends, girlfriend, or with a family. So, you must make the room environment with such materials, which tend to absorb the sound being made inside. Doing so will make your surroundings more peaceful, which is good for not disturbing anyone in your surroundings. 

They may be your neighbours or your other family members at home. We have provided all the possible cost-effective solutions, to make a home cinema room soundproof. If you are still in doubt you can always consult a professional architect depending on your budget to get your desired results, but I would suggest going for these cost-effective methods we have discussed in this blog.
