The study of the relationship between physical SOUNDs and the brain's interpretation of them. Until recently, psychoacoustics has devoted more attention to the behaviour of the peripheral auditory system than to the details of cognitive processing.
(Greek: stereos = solid; phone = sound) Generally, a term used to refer to the spatial distribution of sound, normally using AUDIO technology. More specifically, a form of reproduction which records, transmits and reproduces the original sound with two CHANNELs, regardless of the number of loudspeakers used. Also abbreviated to stereo.
Any VIBRATION in the air or other medium, some types of which are able to cause a sensation of hearing.
Literally, to hear with two ears. Opposite of MONAURAL HEARING. The fact that the ears are some distance apart allows the localization of sound by registering the slight differences in time, PHASE and INTENSITY of the sound striking each ear. Each of these parameters has a different area of effect, intensity being a major factor above 1500 Hz (see SOUND SHADOW), while PHASE DIFFERENCEs (which are equivalent to time differences) are used in localizing lower frequency sounds.
