So here we discuss the way we can place acoustic panels for maximum sound clearance.

Where to place the acoustic panel in home theatre

Sound reflection is one of the main concerns of home theatres. The acoustic panel is used as a sound absorbent which will help in more effective quality perceiving of the sound. The acoustic panel in home theatres should be best placed on the reflecting points. After considering some factors listed in this article installing an acoustic panel will be a lot easier.

Home theatre

It has been considered to be one of the luxurious things to add to your smart home and apartment. Home theatre is an experience in itself.

Why you should place an acoustic panel in your home theatre?

Any sound above the range of 400Hz is directional sound by nature. That is why with the increasing level of the frequency the more directional the sound will become. This the reason why we cannot assume a specific area to place an acoustic panel for every room. So generalizing acoustic panels will be at loss for the user.

With increasing sound reflection there is a health concern of its own. From as simple as a headache to heart disease noise and accumulation of reflected sound is very risky from a health point of view. So acoustic panel in home theatres has a health approach in addition to entertainment purpose.

Each room has its own characteristics so you have to consult with the acoustic panel workers to have things work out perfectly for you. Any home theatre room without any acoustic treatment will have sound reflecting from everywhere. Which will be equivalent to noise rather than pleasant sound.

The original sound from the speaker mixed up with all the reflected sound will have a muddled sound effect. This sound is very irritating and disturbing. Hence Acoustic panel is very important in the home theatre room. Minimizing the reflection will be very effective in perceived sound quality. Here we give you a general idea about the location of the acoustic panel at the home theatre. These general guidelines will not work for all the environment but it will surely help you figure out where you can keep the acoustic panel and bass trap to have the maximize home theatre experience. In the broader sense, the makers and designers of the house like architects, interior designers in most cases do not consider the way residents will perceive the sound. So it is furthermore challenging to have that sonic effect created on the room.

The way furniture is placed in the room overall has a much greater impact than we think. Even though a lot of people seem to be keen on installing home theatres in their house not a lot of people are concerned with the sound system. The installing of the acoustic panel, bass trap, and sound absorbents are in the last of consumer’s priority list.

Types of room for acoustic panel

The number of acoustic panels to be used is dependent upon how to live or dead the room is.


The dead room refers to the room having more sound absorbents like furniture carpeting less exposed area of cement and ceilings. In this dead room, we can use less number of the acoustic panel.


The room has a more exposed area of cement, windows, and less sound absorbent. This room may require more acoustic panel that even recording studios. The L shaped room requires more acoustic panel than a rectangular room. The acoustic panel in home theatres: a simple approach There is a very effective method used by the expert in placing an acoustic panel in home theatres. As in-home theatres even if we treat one-third of the room acoustically it will have the same experience.

Here expert uses a method of using the acoustic panel on both sides of the room in the middle of the room. What this will do is it will absorb all the reflection and echo coming from the central speaker and reduce the reverberation. And the back half of the room remains untouched. With this method, the sound will be more real and organic and the viewing experience of any movie will be maintained.

The acoustic panel in home theatres a wider approach

In general, we have two different types of the acoustic panels in home theatres. They are:


This is an acoustic panel that absorbs the mid to high frequency of the sound wave. These are 2 inches thick. The 2 inches is always effective for mid to high frequencies.


These are designed for a low-frequency sound wave. Trapping low-frequency sound wave is very hard. These are 4 inches thick. The 4 inches will be effective for low frequencies not completely but it will do a good job. To cancel low frequency is a very challenging job. As lower the frequency higher the wavelength we cannot completely cancel the low-frequency sound wave. It will be a lot more effective only if you minimize it to the lowest level possible.

Where to place acoustic panels in home theatre: Reflecting points

For placing the acoustic panel one should think about the reflection point that will affect their listening the most. In general, there will be a 25 reflection point for the central and surround speaker.

You can easily find the reflection point for a particular speaker. You have to take a mirror stand on the wall and move till you can see the reflection point of that particular speaker. Mark that point with a marker and that is a plat where you need to assemble the acoustic panel. Then we can consider the lower frequency sound which is basically from the subwoofer.

You can minimize it by bass trap which should be placed in the wall and floor intersection. You can use the bass trap in as many corners as possible. The more the better. An acoustic panel should be used in all the reflection points and it will give the same effect. Reflection points on the wall, ceiling front, and the back wall should be appropriately found out and marked. For an average rectangular room, we can use anywhere between 15 to 20 acoustic panels.

Some tips to place the acoustic panel in home theatre

You can use very handy tips like leaving a small gap between the acoustic panel and wall. This space act as an extra insulating layer for absorption. This can be done with the bass trap as well. It will give the same result.

The main point is to absorb the sound, so all the basic science concepts should be focused on that. Although the reflection point of the ceiling is a concern, placing an acoustic panel in the ceiling is a very hard job. We should make sure it stays in the ceiling and does not fall on the head of some person. So acoustic panels in home theatres should be placed on the ceiling more meticulously.

There are many companies separately dedicated to placing acoustic panels for home theatres. These companies help you with minimizing as much reflection as possible. They safely install all the necessary acoustic panels and bass traps in the right place. If you cannot do it by yourself, you can contact them. But if you want to do it by yourself it is fine too. Some people use a sponge as an absorbent but it very odd to use that. Maybe for mid to high

frequencies, it will do its job. For lower frequencies sponge will not do any benefit. Lower frequencies will always require a thicker acoustic panel. The thicker acoustic panel is always better than the pores ones. So selecting the acoustic panel that is durable and effective should always be in mind.

Why is it so important to place an acoustic panel?

The acoustic panel in-home theatre is very essential in a special shaped room like a room with more corners like L shaped room. They have more sharp corners so they need more bass traps. They should have special attention. The room with more windows will also require a lot of acoustic panels and bass traps. They are more vulnerable to sound reflection as well as external sound interference. There will be no adulteration from the furniture. It will give more uniform sound distribution and perceiving of sound will be much more effective. This can be a personal choice but it is totally up to you to choose what should be your home theatre room look like.
