Movies are not just about viewing. They’re a combined experience of motion pictures and synchronized sound. Since 1927, sound has been an integral part of movies. Technology has evolved from mono sound to stereo sound to present day digital surround sound technology.
An Overview of Surround Sound Technology
The very first use of surround sound is credited to Disney studios in 1940 for their film Fantasia through a technology they called fantasound. Surround sound technology is sound reproduction in three-dimension through the use of extra speakers. The advancement of today’s digital surround technology is in the form of DTS® Surround and Dolby Digital Surround®, both patented technologies of companies with the same name. Sony also has been the latest entrant into the digital surround sound arena with its patented Sony Dynamic Digital Sound® (SDDS). All three technologies use different techniques to produce the life-like surround sound; However, they tend to present near equal results with one having a slight edge over the other in some domain of sound reproduction.
You must seen have seen present day surround sound speakers labeled as 5.1, 2.1 or 7.1 and Dolby®/DTS® enabled. This simply means that your speaker is able to reproduce sound through either one or both of these technologies. Now, let’s get into what causes the names of 2.1, 5.1, or 7.1. The names 2.1, 5.1, and 7.1 simply indicates that the speaker system comprises of two, five, or seven speakers with one dedicated subwoofer to handle the bass audio frequency range. The 5.1 surround sound may also be referred to as 3-2 stereo; the term 3-2 generally refers to three front speakers and two rear speakers. However the 2.1s are known as the virtual surround sound speakers because of their ability to produce the surround effect with use of just two speakers. The 7.1 channel surround is a set of eight speaker channels, commonly arranged as two speakers at the front left (L) and two at the front right (R), one at the center (C), two at the sides again left and right, two speakers at the rear left and right, and the one subwoofer for bass.
