In this article “Where to place Acoustic Panels in Home Theater”, we will help you understand how acoustic panels and their placements will help you achieve the best possible sound quality for your home theater.

Understanding Acoustic Panels - Where to place Acoustic Panels in Home Theater


Firstly, the main property of Acoustic Panels is to absorb and reduce the echo in a space, here by improving the sound quality. Various places such as recording studios, home theaters, conference rooms, office spaces, auditoriums, etc., use them. Also, these panels come in different materials, shapes, sizes, colors.

In home theaters, acoustic panels play a very important role in increasing the overall sound quality. Specifically, they help in reducing the echo and reverberations, which reduce the clarity of the sounds, dialogues or various audio elements. Apart from this, they also improve the surround sound effect from your speakers.

However, without acoustics, it is very difficult to identify the original source of the sound. Due to continuous reflection, the sounds produced from the one speaker mix with the sound produced from the other speakers. Thus, making it difficult to get a very good surround sound effect.

Calibrating your speakers via the receiver will still not be enough if the reflective points in a room is very high. Additionally, very good calibration options are available only in high end receivers. Mid and low range receivers do not provide extensive calibration options.

Therefore, to solve this issue, Acoustic panels play an important role and this article “Where to place Acoustic Panels in Home Theater” will help you in achieving the perfect acoustics.

Points to Consider Before Installation - Where to place Acoustic Panels in Home Theater


While deciding on the placement of acoustic panels in your home theater, there are a few things you need to keep in mind:

Placing panels on the walls: You must follow this as one of the most important principles without fail. You can either cover the entire wall area or the major reflection points of the wall.

1. The placement of panels on the walls behind the speakers help in reducing unwanted echo’s and sound reflections.

2. Identify the direction and path of sound for each speaker and the spot the sound will hit. Once you identify the trajectory, you should treat that particular area of the wall.

Placing panels on Corners: Sounds generally bounces off the corners of the walls (where two walls joint), which causes the echo. By placing panels on these corners, it can help reducing the echo to a great extent. We highly recommend using bass traps in the corners.

Panels covering the Ceiling: This also is an important place to cover as it can reduce reverberations, making sound quality much clearer and crisper. In addition to installing wall acoustic panels, you can also use many affordable acoustic ceiling tiles to decrease the expenses.

Flooring: Just like the ceiling, flooring also plays an important role in increasing the echo and reverberation of the room. It is vital to treat the flooring with absorbing materials. A very good option to treat the flooring is with carpet. If maintaining the carpet would be a problem, the 2nd option is to go with wooden flooring.

Mix and Match Materials: The best way to get acoustic results  in your room is by mixing different materials and panels. In order to cater to all noise frequencies, use a combination of Absorbers, diffusers and Bass traps. This will help you in achieving the best Acoustics for your Home Theater.

Types of Acoustic Panels that can be used in a Home Theater

1. Foam Based Acoustic Panels

These are one of the most popular choice of products as they are extremely budget friendly. PU foam is used to make acoustic panels as they can be easily cut into different shapes and sizes. They can fit even into narrow corners, since foam is compressible.

Foam is a material that easily absorbs sound and does not allow it to reverberate, hence creating less echo’s and sound distortions. They are available in many colours, shapes and are extremely durable and lightweight, making them an ideal option. Also, these are easy to install if you are looking at self-installation, without any professional help.

However, you should only use these panels when the echo in the room is relatively low to medium. These panels are good when the echo is very minimal and when you are using a 5.1 or lesser speaker setup. If the echo is high or you are using high powered speakers, we recommend using a combination of polywool and wood wool board.

2. Fiberglass Wool Acoustic Panels

People most commonly use these panels in spaces that require a higher rate of sound absorption, such as concert halls, recording studios, and other similar places. They are made from compressing strands of glass fiber.

These are highly effective in absorbing various ranges of sound frequencies, hence making it a great option for home theaters. They are also long lasting and durable, making them a cost-effective option.

However, we recommend getting this installed by a professional as fiberglass wool requires intensive care during installation. Fiber glass wool causes itching and irritation during installation. Either hire a professional or take extensive care during installing this material.

3. Mineral Rock wool panels

Similar to Fiber Glass wool, it is recommended to get this installed by a professional as it causes itching and irritation during installation. In spite of this single drawback, fiber glass wool and mineral rock wool outweigh the negative aspect due to their excellent absorbing properties. 

4. Polyester Wadding or Polywool Insulation

The above listed materials are excellent Acoustic Treatment materials. However, their soundproofing properties is very less. Thus, it is important to understand the exact requirement and then choose the right materials.

Choosing the right combination of materials: One of the most common combination of materials used by Acoustic consultants is Polywool with Wood Wool Board.

1. In Home Theaters, a framework is installed with either Plywood or Pine wood. The space between the Plywood is then filled with Polywool insulation (50mm Thickness – 1000 GSM). After this process, Wood wool Acoustic Boards are fixed on to the framework with screws. This is then Finished off with fabric.

2. Currently, professionals are using a Fabric Tucking method which involves the using of Gripper Track channels, PU Foam and Fabric. PVC Gripper tracks are fixed on to the wood wool board using screws as per your design and then the fabric is tucked in between the Gripper Track.

3. Gripper tracks helps in achieving any kind of design whether it is simple or complex. Also, Gripper track also gives the option of replacing a damaged piece of fabric.
