The 3D sound is the most realistic sound created, till this time we were able to here a two dimensional stereo sound which lags in differentiating heights of a sound coming from. Yeah you guessed it, in 3D sound system we are provided with stereos which differentiate height. It is tough to explain but very interesting to experience.
Check out the video below, that’s Awesome. Explanation and Hearing Sound in the third Dimension.
Traditionally, recordings have been made using two methods: mono and stereo. Mono uses a single microphone to pick up sound, while stereo uses two, spaced apart from each other. Binaural recording takes the stereo method one step further by placing two microphones in ear-like cavities on either side of a stand or dummy head. Because the dummy head recreates the density and shape of a human head, these microphones capture and process sound exactly as it would be heard by human ears, preserving interaural cues. The effect is best experienced over headphones, with a clear distinction between left and right perspectives. It’s a simple concept, but when done with high-quality microphones and played over equally high-quality headphones, the effect is eerie: it fools the brain into believing it’s hearing the sounds firsthand.
The illusion creates three-dimensional audio, which is not to be confused with surround sound. Interchanging those terms is the quickest way to amuse — and sometimes annoy — an acoustician. A surround sound system employs multiple speakers to create a 360-degree field around the listener. Say you’re watching a film presented in surround sound: you’ll see an explosion on one side of the screen, and a speaker on the corresponding side of the theater will emit a barrage of sounds. A theater equipped with Dolby Atmos, the company’s most recent iteration of the technology, effectively envelops the audience. But by recreating exactly what your ear hears in any given scenario, binaural audio accomplishes a far more natural 3D sound without a costly speaker.
