How humans perceive sounds? The answer to this question and all its related implications belong to the range of interest of Psychoacoustics. Although every possible sound in nature can represent a potential stimulus for a psychoacoustical investigation, the most used signals are speech, music and selected type of noises (i.e. in working environments) since they cover the widest range of auditory events that humans are subjected to. Moreover, these signals relate to more complex and interesting processes of human brains. What makes psychoacoustics fascinating is that it crosses traditional boundaries between academic disciplines: fields like medicine, music, cognitive neuroscience, psychology and several sub-domains of acoustics equally interact.
For instance, in architectural acoustics are of primary interest the relations between physical parameters and human perception.
Binaural hearing, sound quality, just noticeable difference, loudness and masking are some of the common keywords to be heard in psychoacoustics.
