How Does The ?surround-sound?

How does "surround" technology work? Dolby Laboratories's surround sound places sound around the audience so that you can make you feel like you are actually there, by the effect in the movie. The main purpose is to use directional sound from various places in the room according to the depth, clarity and clarity of the room. Beginning with a standard called Dolby Stereo, two separate left and right channels were introduced, doubling the other speakers and providing more than one left and right channels around the audience.

What you are familiar with is surround sound. Surround sound is a 2D experience created by three or more speakers creating sounds around the listener and creating a more realistic experience. It encloses you, but since it stays at a fixed level, you can not get height or depth. Do you have a virtual barber shop on YouTube? If not, please check to better understand what the binaural audio is. Binaural audio is a method of recording sound using two microphones on an analog head with ears and other human characteristics. It was created to make the audience feel like they are in the room from which the sound comes from. Although it is not perfect because it uses left and right playback channels, it is getting closer to 3D audio, but still the height and depth of 3D audio are missing. Also, since the original head and ears are not yours, there may be errors in the position and sound quality. The previous article on binaural audio is here.

Long-term philosophical discussion focuses on the question "When a tree falls in the forest, no one around it has heard it, does it really make a noise?" Without a receiver, is the wave really considered a perfect sound? Of course, because the so-called "particle interaction" allows the vibration waves to be transmitted from one place to another, the sound can propagate. However, ultimately, mechanical acoustic waves require receivers to complete their trip. Although there may be objects receiving the transmitted waves, they are hardly detectable as they oscillate at such a high frequency.
