A spatiality , including the impression of spatiality, is not felt at low volume in a closed room . Sources of sound can be: speakers , singers or individual musical instruments , which can also be localized at points, or a choir or orchestra . The greater the volume and the stronger the sound reflections arriving from the side , favored by the narrow room width, side galleries and / or inclined sound reflectors, as well as the avoidance of pillars with a large cross-section in front of the side walls, the stronger the spatiality as a perception that the room is filled with sound to the side from the sound sources to the walls and above them to the ceiling. The room is one of the room acoustic quality criteria. Spatiality is a component of the spatial impression .
The typical sound recording in " multi-microphone ", ie without a main microphone , in which individual mono signals are " panned" between the two loudspeakers with panorama controls (panpots) for directional localization, is called stick stereophony . A more natural connection between the punctiform signals and a certain spatiality are usually missing.
