DTS is constantly seeking better solutions that improve the listening experience. With this in mind, DTS has created DTS Surround Sensation™, which delivers the most realistic, three-dimensional sensation of being completely surrounded by sound — when listening with just two speakers or stereo headphones. It is an elegant and simple alternative that can greatly improve the listening experience for any audience.
Background
Humans perceive sounds in three dimensions. Localization of sound depends on the way that sound waves from the same source differ from each other as they reach the left and right ear. Examples of these cues include such things as variance in spectral frequencies, intensity of volume, and time differences between sounds arriving in either ear. The head, torso, shoulders, and the outer ears modify the sound arriving at a person’s ears, and these factors are also taken into account. This modification can be described by a complex response function, or Head-Related Transfer Function (HRTF). This ability helps us to locate and discern voices from ambient noise and to discern direct sounds versus indirect. It is essential in allowing us to create our spatial awareness.
The Challenge and the Solution
Without any outside influence or assistance, traditional two-speaker sound systems and headphones are not designed or equipped to accurately reproduce these direct and indirect cues. Therefore, the soundstage is one-dimensional, flat, and lacking depth, and allows only limited width. DTS Surround Sensation rises to meet this challenge.
