What Is 3D Audio and How Does It Work?

August 03, 2018

You may have heard about 3D art, but what about 3D audio? In a continually advancing technological age, it makes sense that age-old electronics are now a thing of the past. Engineers strive to make technology increasingly more realistic and alluring in an attempt to provide consumers with a deeply engaging experience. That’s where 3D audio comes into play.

3D sound provides an innovative experience to listeners, causing them to feel like they’re actually immersed in the audio “environment.” Who doesn’t want to feel like they’re a part of their favorite television series or videogames? Rather than listening to an unrealistic or “flattened” sound, 3D audio offers an audible reality that your ears can indulge in with satisfaction.

What Is 3D Audio?

While 3D audio is defined as three-dimensional audio, what exactly does that mean? Three-dimensional audio provides you with an exciting sound experience that projects noise from all directions as opposed to just one focal point. You can hear sounds from the left, right, above you and underneath you. Your surroundings radically transform into an incredibly more immersive experience.

Take video games, for instance. Imagine you’re navigating a first-person point-of-view mission as your character ventures throughout mountainous terrains to reach the next destination. However, it’s nighttime and you must rely on sounds to get to your next checkpoint. You hear a footstep and know your quarry is approaching.

Rather than blindly running in the dark, 3D audio allows you to hear the direction the sound is coming from as if you, yourself, are the character in the game. Pretty cool, right?

How Does 3D Audio Work?

It’s amazing how 3D audio allows us to step into the line of action of a video game, television series or film with ease. But how exactly does it accomplish this seemingly impossible task?

Technicians and engineers utilize a plethora of technological appliances to create a more immersive experience through sound. Often, creators use multiple microphones during the recording process to simulate reality. Various audio devices emit sounds in a sequential rhythm that makes use of how your brain processes noise to make sounds appear more realistic.

For instance, noises that come from the right of you will project louder into your right ear. Then, the sound will reach your left ear in a slightly delayed sequence. This produces the experience of a 3D reality.

3D Audio Compared to Surround Sound

After grasping a brief understanding of 3D audio, you may be thinking to yourself, “Is 3D audio and surround sound the same thing?” Well, not quite.

If you’ve ever ventured to a movie theater to enjoy your favorite film on the big screen, then chances are good you’ve experienced the immersion of surround sound systems. Rather than projecting noise from one given direction, the sound reaches you from various projection points.

3D sound focuses more on producing a natural “rhythm” to the sounds our ears process. While surround sound would play the noise of a child laughing that reaches your ears from various directions, 3D sound allows you to hear this sound in a way that makes your brain believe the child is giggling next to you.
