What is 3D Audio ?
3d Audio Sound
3D Audio Sound (or 3D Sound) perception is the capability of the human auditory system to locate sound in space and more widely, to be aware of the acoustic structure of its surrounding environment. It is the natural way we listen to the world.
The spatial sound perception provides us with several key elements: sound direction and distance, type of location (indoor or outdoor, large or small room, material of the walls and ground …), number of sounds, sound source discrimination (cocktail party effect: we perfectly understand somebody talking in a noisy environment including several people talking).
