Introduction

To improve the home theatre acoustics, proper acoustical materials like absorbents and diffusers are used to improve the quality of the sound.

Home Theatre Acoustics plays a very vital role to improve the quality of the sound, so it’s better you incorporate a proper acoustical wall panel and other acoustical materials at the time of your home interior to improve the room acoustics to avoid any acoustical defects, and, to have a wonderful experience while watching any movie.

A home theatre can be a great way for families to bond with each other while also providing endless hours of entertainment. Further, it can also help to raise the value of your home.

A nice home theater space necessitates a significant amount of effort. Home theatre with projector, as well as picking the right style of seats, proper theater lighting, and, of course, the right speaker, and proper acoustical material which most people pay the least attention to.

If you are planning to set up a Home Theatre System at your place then after reading this blog post you will learn about few key factors like-

1-What is Acoustics in Home Theatre?

Acoustics in-home theatre deals with controlling the different properties of sound to create an immersive sound experience for you to enjoy and mimic the experience of an actual professional theatre. The properties may include controlling the reverberation time or simply being put to control the echo in the room.

For home theatre acoustics, we strategically place different acoustical materials, like acoustical wall panels, for sound to reflect and create a surround sound effect, hence improving the quality of the sound. Also acoustically insulating the room so that sound doesn’t escape outside and disturb the surrounding areas and much more.

A home theater that has addressed acoustical issues enables the movies to be far more involving. They draw you in, and you connect to them in an entirely different way.

The quality of sound can vary quite drastically with changes in its frequency for example the way the low bass sound is tackled is completely different from tackling a high pitched sound which makes more of a squeaking noise.

If we talk about the low bass sound, even distribution in the room is of utmost importance along with placement of the reflective materials so that two major problems can be avoided namely one being the cancellation of the bass in areas with conflict in sound and its reflection and secondly, the over-amplification of bass in certain areas.

2-Factors Affecting the Acoustics of a Home Theatre

The Design of the Room (Shape and Size)

When it comes to home interior, the shape and size of a home theatre (square or rectangle, etc.) influence the quality of the sound.

A rectangular-shaped room is better than squared shaped room because square space has odd harmonic distortions. According to the 3D squared ideal dimension of a room for a good home theatre experience is- width = 1.6 x height; Length = 2.6 x-height.

Secondly fewer the windows, the better it is for the home theatre design.

The finishing material of the home theatre

The material of the wall, floors, and ceiling will also be responsible for deciding the number of acoustic panels and their locations for your home theatre. Like if the flooring material is hard, the reflection of sound will be more, so there will acoustic panel requirement on the ceiling as well.

3-What are Acoustic Panels

Acoustical panels are sound-absorbing panels that are usually made of wool or foam. They are of two types- Absorbents and Diffusers.

As the sound waves bounce from the hard surfaces, these acoustic panels help to dampen any extra echoes and reduce the number of waves rebounding throughout a space, thus improving the quality of the sound of your home theatre acoustics.

The main purpose of acoustic panels/ acoustical material is to maintain the Reverberation Time in a room depending on the space requirements. Their job is to cover up the imperfections of the shape and size of the room.

In a space like a library, where complete silence is required, the number of acoustic panels will be more there, but for home theatre, the panels will be fewer in comparison as we have to control the sound.

4-How many panels do I need?

There isn’t any fixed number for the panels while installing a home theatre. Just some variables are there to necessitate the installation of additional panels. For example, square-shaped rooms, having more reflection points, require more panels.

A room with more windows and more volume will need more panels as compared to a room with lesser windows and lesser volume.

Secondly, the material of the wall, floors, and ceiling will also be responsible for deciding the number of acoustic panels for your home theatre.

To have good home theatre acoustics, all the four walls, floors, and ceiling should have strategically placed acoustical materials like acoustical wall panels, bass traps, etc. that will help to improve the sound quality of the room and hence better acoustics.

5-Where should I place my Acoustic Panels

Location of Reflection Point

I have already discussed the factors affecting acoustics, and it’s difficult to changes those factors, so you have to work on whatever space you have.

You have to strategically locate your sound absorption material for acoustic treatment. The location and orientation of acoustic Sound Absorbing Panels can have a huge impact on the quality of the sound.

Before starting placing these panels, you’ll need to discover the first reflection point. The first reflection point is the mirror point between the monitor or loudspeaker and the listening position. These are on the two walls on either side & the ceiling of the mixing or control desk. You should eliminate this reflection point to get a clean and crisp sound.

To locate this, all you need is a mirror, something to mark with, and someone to assist you. First, with a person holding a mirror on one parallel sidewall, turn on a pretty continuous sound from the speakers like a song or anything. Then, move the mirror around the wall until you can see the speakers in the reflection.

Mark it on these surfaces to indicate their location. Repeat the same process on another wall. Now you got your first point to place soundproofing material or noise absorber. You can place absorbents at the first reflection point, but for a better experience, a medium curve diffuser will be a better choice.

These diffusers will make your stereo sound wider and more focused. Place these diffusers at both the side walls (vertically), front wall (horizontally), and rear wall (vertically). At corners, sound bounces worst, so place thick absorbent panels at all four corners (total 8-panels) on both walls of the corners. And at the ceiling place, two absorbent panels also called cloud’ at the first reflection point and two above the seating area.

To have a better experience, you can also add, diffuser panels at the right angle of the seating area and two diffusers at the corner and also increase the ceiling absorbent panels or cloud.

Conclusion

We have now seen several important factors that affect home theatre acoustics and also have discussed the relevant points to improve the quality of the sound like using acoustical materials- acoustic wall panels, diffusers, etc. They will not only improve the acoustics of the space but will also help you to give an immersive feeling while watching any movie.

But to get the best results, it is better you consult any acoustics consultant before using any acoustical materials or any acoustical wall panels. They will give you a better material specification, with acoustic panel placement & number of panels and other relevant information for your home theatre.
