How to hear TV better
Latest flatscreen TVs have the solution on how to hear voices better on TV is to have either a good Soundbar or fit a good home theatre system. We shall give a short introduction as to what TV soundbars are and how home theatre systems work.
What are TV Soundbars
A TV Soundbar is the latest sound system to improve the sound quality of a flat TV. Sound bars are easy to install and has only one long thin speaker mounted directly in front just below the TV. Most soundbars have an extra Sub-woofer to improve the sound of explosions or drums - the low frequency sounds. The picture here shows how soundbars are placed in front of a TV. The thin long speaker just below the TV is the soundbar and the speaker below it inside the cabinet is the subwoofer. The subwoofer can be hidden anywhwere in the room.
Sound bars work by sending out focused beams of sound, like beams of light, which gets reflected off the walls around the listener to give the same effect as in a 5.1 surround sound system. Soundbars for TV have their amplifier built-in one of the speakers usually in the sub-woofer. The advantage of soundbars is that it gives very good sound and it is very easy to install. Yamaha are the first ones who built soundbars and their soundbars are still considered the best. Bose also makes very good soundbars.
How to set up TV with surround sound system
The picture here shows how a surround sound system speakers are setup around a TV. What is shown in the picture is a 7.1 surround sound system, but it is more common to have a 5.1 surround sound system set up for TVs. In a 5.1 surround sound system the back 2 speakers behind the viewer is not there.
In a surround sound set up for TV, there is a Center speaker which is placed on top of the TV or just below in front of the TV. All voices of people talking come through the centre speaker. The Left and Right front speakers in 5.1 surround sound system gives realistic sounds of moving objects on the TV. For example a train moving from left to right in a TV scene, the sound is higher from the left front speaker when the train is just entering the picture from the left side. As the train moves to the center of the screen, the sound from the front left speaker reduces, and the sound from the front center speaker increases, and when the train reaches the right side of the screen, the sound from the front right speaker increases. This gives a very real feeling of the Train moving fast across the TV screen and adds to the enjoyment of TV watching.
The Left and Right rear speakers in 5.1 surround sound system works when the sound is needed to come from behind. The final speaker in a 5.1 surround sound system is the subwoofer and it is the .1 speaker of the 5.1 or 7.1 surround system. The subwoofer output all the low frequency sounds, like explosions, heavy drums, very deep bass sound of talking, etc. Since human ears cannot make out the direction from which the low frequency sound comes from, the sub-woofer can be placed anywhere in the room.
