Surround Sound -  A Mystery Unravelled

Surround sound or multichannel sound is a way to enhance an object's sound transmission coupled with additional audio channels from high-quality speakers that surround the audience. Surround sound is designed to give you, to your side, above you, and also above you, a sound-field. In a home theatre system, the most popular speaker setup is a 5.1 system. We have six separate speakers, each of which can perform a different function. The position of all the speakers has to be fairly accurate, except for the subwoofer, whose location is not much of an importance.

The goal of enveloping viewers with sound from all directions is to immerse them in the sonic atmosphere as indicated by what they see on the screen. That is, whenever a character fires an arrow towards the frame, the surrounding device must accommodate the whooshing sound of the arrow that flies into the camera and then continues beyond the image. To the audience, it feels as if the arrow is flying from the front of the room to the back of the room.

Here are some things to know about surround sound:

things to know about surround sound

Soundbars are definitely an upgrade - Any soundbar will sound pretty much better than speakers from your TV. For little else, the drivers of the soundbar are aimed at the listening location rather than away from you and towards the wall, which makes it easier to understand the dialogues. There are several soundbars in the market that provide clear quality and feature advanced technologies that can produce some convincingly wide images of sound. Combined with a good subwoofer, a soundbar is a great solution for a secondary listening area, where it is simply not possible to install a traditional surround system. Remember this is a generalization though, and again; a soundbar almost never surpasses a traditional surround system. 

On-Wall vs In-wall - In-wall speakers have undoubtedly come a long way and some in-wall speakers sound absolutely fantastic. If you're looking for a discrete, nearly invisible speaker setup, they're the way to go. However, an on-the-wall or a floor-standing speaker sounds much better at the price of an expensive in-wall speaker. When it comes to in-wall, you will have to spend well over a lakh and still get a better quality in half-the-price freestanding speakers. In comparison, in-wall speakers are also harder to position, as their placement is determined by the stud configuration of your room.

Bigger is always better - A big driver, or multiple drivers, are most efficient in moving a lot of air. If you're in a big room looking for a lot of effects, we recommend massive, floor-standing speakers. However, in the case of subwoofers, you can buy a large subwoofer or a smaller one with a comparatively better amp in accordance with your budget and decor suitability.

TVs don’t go in a corner - As we are attempting to recreate the theatre atmosphere at home on a smaller scale, audiences can refrain from installing their televisions in a corner. If the TV is placed into the corner, everything is distorted, making it nearly difficult to find the placement for front left/right speakers accurately, or to arrange the surroundings so that they can function with different seating locations.

Position the surround speakers behind you - Surround sound is for having the audio both around and behind you, thus the surround speakers should be positioned behind you unless you are opting for a seven-channel audio system. Dolby 's advice is to "position them slightly to the back of your seat, and angled toward it." In-ceiling speakers perform fantastically well in surround applications, as well as in non-Atmos setups. In-ceiling speakers work terrifically well in surround applications, even in non-Atmos setups. There are many sounds that are directed to the surround channels and naturally occur overhead, such as aeroplanes, helicopters, rain, and crowd noise. In such cases, in-ceiling speakers are highly recommended.

The main thing which distinguishes a home theatre from a standard TV setup is the surround sound. To establish a proper surround-sound system, you require two or three speakers in the front and two or three speakers on the sides or at the rear. Also, it needs an AV receiver (AVR), which helps in decoding different surround sound codecs. The audio signal is divided into multiple channels so that different sound information arises from the different speakers.
