hearing: 1: to perceive or apprehend by the ear; [...] 1: to have the capacity of apprehending sound; [...] 1: the process, function, or power of perceiving sound; specif: the special sense by which noises and tones are received as stimuli; [...] [217]
The main attributes used for describing a hearing event are:
The perception of a direction of a sound source depends on the differences in the signals between the two ears ( interaural cues: interaural level difference (ILD) and interaural time difference (ITD)) and the spectral shape of the signal at each ear ( monaural cues). Interaural and monaural cues are produced by reflections, diffractionsa and damping caused by the body, head, and pinna. The transfer function from a position in space to a position in the ear canal is called head-related transfer function (HRTF). The perception of distance is influenced by changes in the timbre and distance dependencies in the HRTF. In echoic environments the time delay and directions of direct sound and reflections affect the perceived distance.
