KembaraXtra-Psychology - audiogenic seizure
An audiogenic seizure is a convulsion triggered by prolonged exposure to high-frequency sounds, particularly studied in animals such as rats, mice, hamsters, and rabbits, and it links conceptually to infrasound and ultrasound.

KembaraXtra-Psychology - audiogram
An audiogram is a graphical record of absolute thresholds for pure tones across frequencies measured with an audiometer, often plotted as hearing loss (deviation from average thresholds) in decibels versus frequency, providing a full profile of auditory acuity.

KembaraXtra-Psychology - audiogravic illusion
An audiogravic illusion is a sound-localization error occurring when the body is tilted away from upright without visual cues, causing the sound source to be perceived where it would be relative to the body if the body were upright; it is compared with the audiogyral illusion.

KembaraXtra-Psychology - audiogyral illusion
An audiogyral illusion is a sound-localization error where a sound fixed relative to the head (for example on a boom a few feet in front of the nose) is nevertheless perceived as coming from directly overhead when the head turns, and similar overhead mislocalizations occur when a person rotates on a platform with the sound rotating with them, or when vection is induced by a rotating striped drum while a sound source remains fixed outside. The illusion was discovered by Hans Wallach (1904–98) and published in 1940, and it is explained because head/body rotation normally changes transient disparities, phase delays, and sonic shadows except for sources directly above or below; terrestrial experience therefore biases interpretation toward an overhead source. It is compared with the audiogravic illusion and relates to sound localization.

KembaraXtra-Psychology - audiokinetic response
An audiokinetic response is an automatic eye movement triggered by changes in body position relative to a continuous sound source, helping maintain gaze fixation on potentially important objects.

KembaraXtra-Psychology - audiometer
An audiometer is a device for measuring hearing sensitivity across sound intensities and frequencies, producing data that can be summarized in an audiogram; audiometric describes related measurement.

KembaraXtra-Psychology - audiometric zero
Audiometric zero is the reference “normal” or average intensity threshold for hearing at a specified frequency.

KembaraXtra-Psychology - audition
Audition can mean (1) the act or experience of hearing, or (2) a trial performance (audition) for entry into a musical or performing group, course, or production; the word comes from Latin for “hearing.”
