Okay, so you have just witnessed the mesmerizing sound of Dolby Atmos and the sound system has caught your attention. But do you know what is Dolby Atmos and what are the necessary things to consider before buying this system?

Don’t worry. Here’s all you need to know about mesmerizing sound technology. First, let’s see its definition.

What is Dolby Atmos?

If you have been to any movie theatre, you might have experienced the cool sound around you. It seems you are actually in that particular place in the movie. It’s an advanced sound technology that produces a 3D sound so that whatever you listen to, it makes you overwhelmed as well as creates an illusion.

This is not only found in movie theatres now but in your TVs, Home Theatre, AV receivers, and other audio devices. This was developed by Dolby Laboratories thinking about giving a multi-dimensional sound experience to the audience.

What is the Dolby Atmos system of working?

Dolby Atmos is now a sensation to people because of its beautiful sound system. So, the business has also increased. Before buying, it’s necessary to research the topic.

Let me give you an overview of how it works. There are only two channels in the Stereo sound system which are left or right. It overlaps dialogues or sound effects to the music or other effects. If you check the 5.1 surround system, you will get 5 speakers which are properly placed to the left, right, center, and rear place of a listener. The surround sound system has more channels like Dolby Atmos which has speakers everywhere around the listeners.

It creates sound, bounces back to the ceiling, and then reaches down to the listener. The result gives a richer experience to the audience. Dolby Atmos is used to create more depth to the movies and music. Suppose you are watching a waving of a river on the screen.

If you use a stereo sound system, you will only get the sound moving from left to right speaker but if you use Dolby Atmos, you will get the coming from your back and circling around you as if the river is just a few steps away from you. Isn’t it so amazing?

To get a better quality, you need to have multiple speakers, especially over your head. You can set it up in your home also.

What are the supporting devices?

If you want to experience the sound of Dolby Atmos, you need to check the device also if that supports it or not.
