What Is 3D Audio? The Game Changers For Future Audio Industry

What is 3D audio, and how does it work? Discover the advantages and disadvantages of the future technology via this article. Click for more info!

Surround and stereo sound have their advantages, but none can beat 3D audio in terms of realism. 3D audio gives the listener the maximum sense of realism to increase the experience. So, what is 3D audio?

A 3D sound effect is a group of sounds that control the music produced by surround speakers, stereo speakers, headphones, or diaphragms.

It creates virtual positions of audio sources in three-dimensional space. Listeners can feel the noise on the sides, above and below, when experiencing.

3D sound is another name for spatial vibration. Some industry experts may point out that there is a technical difference in the definitions for both. 

Yet, both 3D sound and spatial harmony can bring audio experiences that allow listeners to determine the direction and distance of the tone sources accurately.

This perceived difference comes mainly from tricking the listener's brain. It makes us feel that the noises are coming from different directions in the three-dimensional space around them.

How Does 3D Sound Affect Your Brain?

The manufacturer creates three-dimensional audio recordings using two microphones placed inside a human-like head and aligned with the human ear.

The microphones capture melody from two channels simultaneously to create biomimicry. This concept describes the imitation of the minor signal variations that occur when each signal is sent to the brain.

Our brain is a wonderful organ. It allows one to determine the direction of the surrounding sound thanks to specific vibrations of the sound waves.

The technicians created "multi-ear" mannikins with sensitive microphones in the prosthetic ear canal to develop this multi-dimensional effect. They then measure how the vibration changes as it travels through the air to each device.

The name of this process is the head-related transfer function (HRTF).

This data plays a vital role in developing headphones or audio devices capable of tricking our brains.

The Differences Between The 3D And Surround Sound

When it first appeared in cinemas, surround sound caused a massive revolution with audiophiles. It allows the listener to hear from all four sides.

Often people will use six to eight speakers to create a particular composition.

According to the ITU, the 5.1 system recommends using six speakers. Another popular arrangement is a 7.1 system with eight speakers.

Compared to two-speaker sound systems, surround harmony allows listeners to have a more immersive experience. But when compared with three-dimensional sound, it still has limitations.

At least this kind of tone doesn't let you hear from above and below, right?

Surround audio requires the use of multiple external speakers to provide a directional sound source. On the contrary, you must equip a headset to enjoy the three-dimensional effect.

The Uses Of 3D Audio

How does 3D audio work in headphones? Let's find out in this section.

In Gaming Industry

Playstation is a pioneer when it comes to applying three-dimensional audio technology to their PS5 devices. It aims to give gamers a realistic space.

Games in the first person, like the action-adventure or horror genre, will bring unprecedented sensations. The nature of these games is often sound-oriented. Players need to listen carefully to determine the direction of the enemy.

In short, three-dimensional melody effects enhance the gaming experience.

In VR Industry

The term virtual reality is gaining popularity. It creates an entirely different world to satisfy human imagination. You will transform into a character in this space instead of just staring at the flat screen.

But the hologram is a factor. Relying on it alone is not enough to trick your brain. The 3D Audio Headset is the perfect complement to immerse you and complete the experience.

Downsides Of 3D Sound

There is no doubt that spatial sound will become a trend in the future.

Powerful technical innovation brings realistic and vivid harmony quality. Many industries can benefit from this technology, including gaming, film, or music.

However, the lack of standardization and proprietary technologies limited users' access to spatial sound. Licensing the technology is also extremely expensive.

Not all consumers have the financial resources to equip such new equipment for their home theater system.

You can refer to a few brands: Dolby, VisiSonics, Sennheiser, and Auro.

The fact that most home appliances do not come with spatial acoustic engineering is another matter. If your TV or game console isn't coded to support hologram audio, you can do nothing.

It will be very frustrating if you just bought a new 3D headset and found that you can't use it. The only solution is to upgrade your other devices. But it comes back to the budget issue.

Is 3D Audio Worth It?

Spatial tone brings a revolution when it comes to creating the most authentic experiences for listeners.

If you are hardcore gamers or audiophiles, this technology will change the game completely. It helps you to immerse yourself in work thoroughly. It will be a new and unforgettable experience.

Frequently Asked Questions

Do Soundbars Have Three-Dimension Sound?

Yes, they do. Soundbars capable of spatial sound will have several different audio channels. Each channel is responsible for playing different parts of the sound.

What Is Binaural Rendering?

Dual audio rendering is a signal processing technique. It can produce a headphone-delivery stereo audio signal from a real-world audio source at a specific location.

Does Xbox Have Three-Dimension Audio?

This component of the PS5 has been widely advertised, but the Xbox Series X and S offer the same feature. The two Microsoft consoles are equipped with the 3D spatial sound that you can enjoy with headphones.

Final Thoughts

Spatial melody effects, or three-dimensional sound, are a testament to the development of technology. It gives users the most authentic and transparent feeling. It will not be surprising that it will be more popular in the future.
