Sound localization is a listener's ability to identify the location or origin of a detected sound in direction and distance. The sound localization mechanisms of the mammalian auditory system have been extensively studied. The auditory system uses several cues for sound source localization, including time difference and level difference (or ...
Hearing. Video showing how sounds make their way from the source to the brain. Hearing, or auditory perception, is the ability to perceive sounds through an organ, such as an ear, by detecting vibrations as periodic changes in the pressure of a surrounding medium. [ 1] The academic field concerned with hearing is auditory science .
Equal-loudness contour. An equal-loudness contour is a measure of sound pressure level, over the frequency spectrum, for which a listener perceives a constant loudness when presented with pure steady tones. [ 1] The unit of measurement for loudness levels is the phon and is arrived at by reference to equal-loudness contours.
Sound is defined as " (a) Oscillation in pressure, stress, particle displacement, particle velocity, etc., propagated in a medium with internal forces (e.g., elastic or viscous), or the superposition of such propagated oscillation. (b) Auditory sensation evoked by the oscillation described in (a)." [ 2]
Selective auditory attention. Selective auditory attention, or selective hearing, is a process of the auditory system where an individual selects or focuses on certain stimuli for auditory information processing while other stimuli are disregarded. [1] This selection is very important as the processing and memory capabilities for humans have a ...
According to the theory, auditory learners must be able to hear what is being said to understand, and may have difficulty with instructions that are drawn. They also use their listening and repeating skills to sort through the information presented to them. [3] Few studies have found validity in using learning styles in education. [4]
Hearing range describes the frequency range that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies ...
Dichotic listening. Dichotic listening is a psychological test commonly used to investigate selective attention and the lateralization of brain function within the auditory system. It is used within the fields of cognitive psychology and neuroscience . In a standard dichotic listening test, a participant is presented with two different auditory ...
