What is 3D sound effect?

3D sound effects are stereoscopic , a next-generation developed three-way interconnect standard.

This type of sound can help listeners enjoy the surround sound, creating a surround sound, helping listeners can immerse themselves in music and movies.

Working principle of 3D . sound

You can understand that 3D sound affects your ears in the same way as 3D images affect your eyes.

Usually, sound systems often use multiple speakers to create a surround sound space. With 3D sound has created a new development when not only emitting sound in one direction for the listener, but also can create sound that surrounds the space . It is the layering effect that helps the 3D sound to produce good sound quality.

3D sound systems usually arrange a certain number of speakers:

• For the center speaker , it plays the role of playing the actor’s lines and is placed in the center position.
• The two left and right speakers, placed on either side, play the role of playing sub-dialogues, sounds and effects.
• Then, two side speakers are placed on either side and higher than the viewer’s sitting position, the effect is to provide the sound to create a surround effect.
• Finally, the subwoofer has the effect of creating subwoofer sound and frequency, the placement of this speaker is often up to the comfort of the user.

Origins of 3D . sound capture technique

In 1881, Clement Ader was a 19th-century French engineer who invented the Theatrophone, a telephony audio transmission system for playing the sound of Opera concerts in Paris.

At that time, a pair of microphones was installed in front of the stage and in the direction from left to right. The audio signal is transferred to the phone receiver and then transmitted to the listener.

The origin of 3D sound recording technology also dates back to 1933, when AT&T Bell Laboratories debuted at Chicago World’s Fair. They use a mechanical dummy named Oscar combined with microphones mounted on either side of the ear. Oscar is located in a recording studio, listeners use signal receivers to hear the most accurate sounds.

Pros and cons of 3D . audio

Pros: 3D sound gives users a good audio experience that surrounds any space. 3D sound has created a quality surround sound space.

Defect:

• Most electronic devices and home technology do not support 3D sound today.
• You can buy headphones with 3D audio, but not all devices have built-in technology and compatibility with 3D audio.
• Devices possessing 3D sound are quite expensive in the market.

Learn the Auro-3D . format

What is Auro-3D? How is Auro-3D different from 3D audio?

Auro 3D is the next-generation three-dimensional stereo standard. Auro-3D sound delivers an immersive audio experience, creating surround sound that makes you feel like you’ve stepped into the real world of movies.

Auro-3D uses overhead sound quality, the sound is synthesized, natural sounds can be heard.

The Auro-3D format and 3D sound have quite a few differences not only in the quality to experience but also in the compatibility of the content.

We can install an Auro-3D support system or upgrade from an earlier system. All Auro-3D formats stand out in terms of other audio formats, especially the ability to stratify in the Auro-3D system.

The application of Auro-3D helps users to have sound quality with more enjoyable experiences in cinema, car field, virtual reality, …

How to set up a 3D sound system at home

Speakers are usually placed on 5.1 speakers and there is always a space below the speaker. Right at that space, you should place the Auro-3D’s upper floor speakers and are composed of 4 speakers.

For the top speakers will be placed vertically with the bottom speakers and tilted at an angle of 25 degrees.

An important trick in speaker installation is that you should position the speaker angles against each other to enhance the listening experience. When installing a 3D sound system, the principle should be followed as closely as possible.

How is 3D sound different from surround sound?

Surround sound can be understood as sound that can give users a listening experience in 4 directions: left, right, top and bottom . For surround sound is usually used at least 6 speakers . Surround sound often gives listeners a truly immersive experience in your world and gives the illusion of aural space in your brain.

With surround sound, it only gives the listener the feeling from 4 directions, but 3D sound will bring an omnidirectional sound experience . Certainly, listeners will have a better experience from 3D sound. In addition, the technology of 3D audio allows listeners to accurately identify sound direction.

For normal 3D sound the effects are generated by speakers and sound processing placed anywhere in three-dimensional space. In fact, three-dimensional space will give the listener the feeling of tricking the listener’s brain into thinking that the sound is coming from many different directions.

Some things about 3D sound you may not know?

The important point of speakers using 3D sound must have their own channels and have their own signal or separate matrix channels.

3D audio allows the audio to be extracted or broken down from several separate channels. That’s also why the system of speakers 2.0, 5.1, 7.1, etc. is attached to the surround sound format.

Different or separate, independent channels with frequency range from 20Hz to 20kHz . Sound system 2.0 is a system with 2 channels, also known as Stereo. The 5.1 system includes 5 separate channels of 5 different speaker systems, for number 1, only the subwoofer specializes in frequency distribution from 3Hz to 120Hz.
