A Detailed Comparison of Dolby Atmos and 7.1 Surround Sound Formats
Now that we have a quick and clear understanding of both 7.1 and Dolby Atmos surround sound, let’s compare them in detail.
Dolby Atmos
Dolby Atmos is a revolutionary technology that has changed the way we experience sound in music, TV shows, movies, and gaming. It enables sound to move freely in 3D space, creating an immersive and realistic audio experience. Here is a breakdown of what Dolby Atmos is and how it works:
What is it?
Dolby Atmos is a surround-sound technology that uses height channels to create realistic and immersive soundscapes. It has revolutionized the way sound is delivered in commercial cinemas and home theaters.
Dolby Atmos was developed and introduced by Dolby Laboratories in 2012, and unlike traditional surround sound systems that use channel-based sound distribution, Dolby Atmos is an object-based technology.
It treats each sound as an individual audio object with its own location and motion in 3D space to create a more realistic sound experience. As a result, you’ll feel immersed in the movie or game as the sound comes from all directions.
Dolby Atmos was introduced to cover the flaws of Dolby Digital sound, and it is better than everything and anything offered by Dolby.
How does it work?
As we already mentioned, Dolby Atmos is an object-based audio format, which means each sound is treated as an individual object that can be placed anywhere in the 3D sound field. Dolby Atmos achieves its immersive sound with the help of specialized hardware and software.
Audio engineers encode the audio content with metadata that describes the movement and position of each sound in 3D space. Then, this metadata is decoded by a compatible audio processor to determine how each sound should be reproduced in your specific speaker setup.
To reproduce overhead sounds, Dolby Atmos uses height channels that are created through speakers on the ceiling or upward-firing speakers. These speakers can be discrete or built into a wall or ceiling. This is how Dolby Atmos works to create an enveloping sound experience. Many streaming platforms are now shifting to Dolby Atmos-compatible content.
Speaker Configurations
The speaker’s positioning and configuration matter for the immersion of sound. A variety of speaker configurations are available that are used to create a Dolby Atmos sound system.
Speaker configurations are commonly denoted as X, Y, and Z. X is the number of traditional surround sound speakers; y denotes the number of subwoofers; and z is the number of overhead or height speakers.
For example, the most common speaker configuration is the 5.1.2 system, which has five front speakers, 1 subwoofer, and 2 height/overhead speakers. Other speaker configurations include 7.1.2, 9.1.2, and 11.1.2 systems.
The number of speakers in the system determines the number of discrete sound objects that can be created. Subwoofers cover the low-frequency bass sounds. Height channels are crucial for creating sounds that come from above, immersing you fully in the audio environment.
Sound Precision
Dolby Atmos delivers a more realistic and captivating sound experience than traditional surround sound systems. This is because of the more precise sound placement of the height channels, which makes the soundscape more enveloping.
Sounds are rendered with remarkable precision, moving all around you and even overhead. It creates a realistic experience, making it feel as though you’re inside the action. Although dialogue clarity in Dolby Atmos is almost the same as on the 7.1 surround system, it takes the lead in surround sound effects.
Immersive Experience
Dolby Atmos creates a more immersive audio experience than traditional systems. With it, you’re not just listening to the sound; you’re experiencing it. It is because of its object-based audio technology and inclusion of height speakers.
This immersive experience enhances your emotional connection to the content, and you can feel like you are right in the middle of the action.
Compatibility
Dolby Atmos can’t just work with any hardware or content. It requires compatible speakers, hardware, and content for proper playback. This may include an AV receiver, soundbar, or A/V processor, as well as speakers that can support the required channels, like overhead or height speakers.
Additionally, your source content, such as games, movies, or streaming services, must be encoded in Dolby Atmos. Ensure all components are Dolby Atmos-ready to experience the immersive 3D audio that this technology offers.
Flexibility
Dolby Atmos is a flexible technology that is adaptable to a variety of room sizes and speaker configurations. You can have a Dolby Atmos setup in a small living room, dedicated home theaters, movie theaters, and even mobile devices, and it will adjust to optimize your audio experience.
You can also choose any speaker configuration based on speaker availability, room size, and personal preferences. Additionally, Dolby Atmos is compatible with a wide range of content, including TV shows, movies, music, and games.
