They were created by Dolby Labs but they weren’t used until 1992 when the film Batman Returns was released. 5.1 Surround Soundĥ.1 systems first appeared in 1976. Let’s see the basic characteristics of both of these systems and, hopefully, make your purchase easier.

These systems are relatively easy to install and also more affordable than some more complex systems (the ones with in-wall or in-ceiling speakers, and this is probably what makes them so popular among customers. The first letter refers to the number of loudspeakers while the second refers to the number of subwoofers.

In this article, we will focus on the more popular group – X.Y systems, 5.1 and 71. Types of Surround Sound Systems?Ĭlassification of surround sound systems is commonly made based on their configuration, which divides them into two groups – X.Y and X.Y.Z systems. An assembly like this creates a true cinema-like experience, as you can hear every sound perfectly – you can feel the music, hear the dialogues, and experience special effects, etc. These speakers physically surround the listener(s) who sits in a “sweet spot” located in the center of an “equilateral triangle” formed by the speakers. The true effect of surround sound is achieved by using home theater speaker systems that consist of several speakers and one or more subwoofers. However, we don’t believe that it is possible to trick anybody’s brain and if you are a true fan of surround technology, you’ll hear the difference between true and virtual surround. They can also receive a 5.1 audio signal and convert it into a two or three-channel signal, making you believe that it is true surround sound. This is achieved by using speakers or soundbars that receive two or three-channel signal and trick your brain into believing that you’re listening to a true surround sound. Surround sound technology is often confused with virtual surround sound technology, which implies the usage of fewer speakers and the creation of an impression of surround sound effect. Along with the improvement of Dolby formats, surround sound technology was improved and it became available to the consumers during the 1990s. This question was raised again in the 1950s (again, in the film industry) but its real expansion didn’t start until 1975 when a new sound format Dolby Stereo appeared (you can find a more thorough explanation of this format in the text below).

At the time, the technology was too expensive for application because it required numerous speakers to create the effect of surround sound in a movie theater, so the creators gave up on it. As you could probably guess, surround sound systems first appeared in the film industry and Disney was responsible for this innovation.
Well, this is far from the truth as surround sound systems came into existence with the introduction of surround sound audio formats back in the 1930s. Surround sound systems have become popular only recently and this is what makes people think of them as of some new technology.
