Auditory event

Auditory events describe the subjective perception, when listening to a certain sound situation. This term was introduced by Jens Blauert (Ruhr-University Bochum) in 1966, in order to distinguish clearly between the physical sound field and the auditory perception of the sound.
Auditory events are the central objects of psychoacoustical investigations. 
Focus of these investigations is the relationship between the characteristics of a physical sound field and the corresponding perception of listeners. From this relationship conclusions can be drawn about the processing methods of the human auditory system.
Aspects of auditory event investigations can be:
Relationships between sound field and auditory events.
The sound field is described by physical quantities, while auditory events are described by quantities of psychoacoustical perception. 
Below you can find a list with physical sound field quantities and the related psychoacoustical quantities of corresponding auditory events.
Mostly there is no simple or proportional relationship between sound field characteristics and auditory events. 
For example the auditory event property loudness depends not only on the physical quantity sound pressure but also on the spectral characteristics of the sound and on the sound history.
