Design: The Scientist
With a large high-definition TV and a surround sound system, it's not difficult to get that movie theatre experience at home. A typical surround system has two or three speakers in front and two at the rear. However, there's been a trend towards sound bars that are able to recreate surround sound in a room with less speakers.
How It Works
With a surround system, the audio signal is split into multiple channels so that different sound information comes out of the various speakers. Typically, there are three channels at the front. The left and right channels gives you the stereo sound, while the centre channel anchors the dialogue and front sound effects. The channels at the side or rear give you a sense of motion and depth, for example, the sound of a train coming from the far left of the screen to the near right side. A good surround sound system is able to recreate that immersive audio experience.
Ask Before You Buy
How many channels do you want for your room? The most common option is 5.1 surround, which means five channels (speakers) plus one subwoofer (denoted by the ".1") that provides the bass frequencies. 6.1 and 7.1 channel systems have six or seven speakers plus a subwoofer.
