The Weber test is a screening test for hearing performed with a tuning fork. [ 1][ 2] It can detect unilateral (one-sided) conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss). [ 3] The test is named after Ernst Heinrich Weber (1795–1878). Conductive hearing ability is mediated ...
The inset shows the electronic simulation. Notably, such electronic systems require more than one speaker. Time difference in a stereophonic recording of a car going past. Stereophonic sound, or more commonly stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective.
The lateralization of brain function (or hemispheric dominance [1] [2] / latralisation [3] [4]) is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other. The median longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum.
The Rinne test ( / ˈrɪnə / RIN-ə) is used primarily to evaluate loss of hearing in one ear. [ 1] It compares perception of sounds transmitted by air conduction to those transmitted by bone conduction through the mastoid. Thus, one can quickly screen for the presence of conductive hearing loss. [ 2]
Left–right confusion. Left–right confusion ( LRC) is the inability to accurately differentiate between left and right directions. Conversely, Left–right discrimination ( LRD) refers to a person's ability to differentiate between left and right. LRC is reported by approximately 15% of the population according to the 2020 research by Van ...
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 ...
The interaural time difference (or ITD) when concerning humans or animals, is the difference in arrival time of a sound between two ears. It is important in the localization of sounds, as it provides a cue to the direction or angle of the sound source from the head. If a signal arrives at the head from one side, the signal has further to travel ...
Diplacusis, also known as diplacusis binauralis, binauralis disharmonica or interaural pitch difference (IPD), is a hearing disorder whereby a single auditory stimulus is perceived as different pitches between ears. It is typically experienced as a secondary symptom of sensorineural hearing loss, although not all patients with sensorineural ...
