NRG Acoustics SG-4: Multichannel surround sound

Surround sound is a way of enhancing the sound processing quality of any audio source with additional audio channels from audio speakers that surround the audience (surround channels), providing sound from a 360 radius in the horizontal plane (2D) not like "screen channels" (centre, [front] left, and [front] right) originating only on the listener's forward arc.

Surround sound is portrayed by a listener position or sweet spot in which the audio effects work most effectively, and features a constant or forward perspective of the sound area towards listener around this location. The technique enhances the conception of sound spatialization by exploiting sound localization; a listener's ability to know the location or origin of a noticed sound in path and range. This typically is achieved with the use of multiple discrete audio channels routed to an array of loudspeakers.

There are many multichannel sorround sound systems based models and methods, differing in reproduction and saving methods along with the number and placement more stations.


NRG Acoustics HJ-17: Areas of application

Though cinema and soundtracks represent the main uses of surround approaches, its scope of application is much wider than that as surround sound enables creation of an audio-environment for all sorts of functions. Multichannel techniques is known to recreate contents as various as music, speech, natural or synthetic sounds for cinema, television, broadcasting, or pc systems. With regards to music content as an illustration, a live performance is able to use multichannel techniques in the context connected with an open-air show, of a musical theatre or perhaps transmissions; for a film specific techniques are adjusted to movie theatre, or to home (e.g. home cinema systems).

The narrative area is also a content that may be improved upon through multichannel approaches. This applies mainly to cinema narratives, such as the speech from the characters of a film, but can also be used on plays for theatre, to a conference, or to blend voice-based comments in an archeological site or monument. As an example ,, an exhibition could possibly be enhanced with topical background sound of water, wild birds, train or machine noise. Topical natural sounds may also be used in educative applications.

NRG Acoustics A-70 - Additional fields of application incorporate video game systems, personal computers along with other platforms.

In this applications, the material would typically be fabricated noise made by the computer equipment in interaction with its user. Substantial work has also been done using multichannel for enhanced situation awareness in military services and general public safety purposes.
