Home Theater Sound

Sound, it is everywhere around us. Sound is what we react to, listen for, enjoy hearing, and so on. But what about sound and how can sound make such a dramatic impact on a nation of entertainment needing people? Let us take a look at what sound is all about and how exactly it functions.

There are different formats of sound. Sound can be mono, stereo, surround, or encompassing. The latter our society has not yet reached but may one day do so. Out of those different formats which are with us today, surround sound is by the far the most popular, and widely used. But what makes this kind of sound so special?

Each speaker in a home theater system can be considered a channel or a tunnel. The more channels you have in an audio system the better the sound becomes. It also becomes a lot more enjoyable to listen to. Let us compare an old radio for this example. Have you ever heard an old 1940s radio crackle and rumble when a song was playing? Compare that to the high fidelity audio you can hear on a basic computer. What is the difference between these two gadgets?

The difference is channels. The more channels you have, the more information you can pump through to the desired sound source, resulting in a much clearer sound. There is also another key thing to note here. The older sounds that we use to hear came to us in an analog format. Analog is the exact opposite of digital. Digital sounds can be reproduced an infinite number of times without losing their quality. It doesn’t matter how far they have to travel or how they get reproduced (unless reproduction is of a lower quality). Analog signals became worse with every reproduction or alteration you made to them. Not too mention they only came in a stereo format.

The digital signals that are formed by the technology of today are passed onto a medium which let us hear those signals. That medium is the speaker. What are speakers? They are translators to say the least. They decode this information of digital signals into a format that produce a vibration in the air, or better known as sound. A speaker is the exact opposite of a microphone. A microphone takes sound from the air in, and sends it along to be produced from the digital format back into an analog format through the speaker.

How exactly is the sound produced in the speaker? All speakers are made up of basic parts such as cones, coils, frames, and so on. When the coil inside the speaker moves around, the cone of the speaker pulls and pushes. This causes the static air in front of the speaker to vibrate according to the digital signal, thus producing “sound” as we know it. What kind of speakers should you look for in your home theater buying experience? Try to find a set that has a really good range of high and low, is capable of handling a good degree of bass, and at a price that is not an unbelievable bargain if you will. In the audio world, you really do get what you pay for.
