An article I wrote for Electronic Products.
What separates these two types of audio technology?
Though they have their differences, surround sound and 3D sound are used in very similar ways. Surround sound involves placing multiple speakers around a room to put you in the center of the action. It makes watching movies and television more realistic. With 3D sound, not only do sounds come from the left and right of you, they also come from above and below you. Basically, it turns things up a notch.
What is surround sound?
Throughout the years that television has been in existence, the two biggest changes to enjoying a program or movie is the clarity of the picture and sound. While the former is well documented, not many know how far sound has come.
In movie theaters years ago, the entire soundtrack was played on one speaker, or a collection of speakers that were placed behind the movie screen. Today, audiences in movie theaters are used to hearing sounds thundering on each side of them. What they expect is surround sound. Now that technology, once only enjoyed in movie theaters, is now common in home entertainment centers.
