2022年3月22日 · In acoustic tonometry, an acoustic trigger signal vibrates the eyeball, and then the frequencies or amplitudes of the responses from the cornea are detected. The trigger signal is generated by an...

Sound and vibration evoke a short-latency eye movement or “sound-evoked vestibulo-ocular reflex” (VOR) and an infraorbital surface potential: the “ocular vestibular-evoked myogenic potential” (OVEMP). We examined their relationship by measuring the modulation of both responses by gaze and stimulus parameters.

It begins by narrowing music to sound and sound to vibration. The focus is on low frequency sound (up to 250 Hz) including infrasound (1–16 Hz). Types of application are described and include whole body vibration, vibroacoustics, and focal applications of vibration.

Yes. High intensity low frequency sound makes your eyeballs vibrate in your head, so you really can see (and feel) it. On a related topic, you can find the damped resonant frequency of your eyeballs by looking at the sweep line on an oscilloscope whose timebase has been set …

Despite the heterogeneity of the intraocular contents (vitreous body, lens, aqueous humor, retina, choroid, etc.) and external restrictions on the part of the eye muscles and eyelids, the outer polymer membrane of the eyeball (sclera + cornea) must be able to vibrate with a strictly certain resonant frequency.

2022年3月22日 · The eye orbit has mechanical and acoustic characteristics that determine resonant frequencies and amplify acoustic signals in certain frequency ranges. These characteristics also interfere with the acoustic amplitudes and frequencies of eyeball when measured with an acoustic tonometer.

Research by the American Air Force has found the resonant frequency of the human eyeball to be around 19 Hz. To determine that figure, 15 human volunteers were exposed to vertical vibrations in the range of 5-50 Hz and their eye movements were observed by …

2011年1月23日 · I believe a number of studies have shown that infrasound (frequencies below 20Hz) can be used to instill a sense of suspense or even fear in a subject. In particular 19Hz is the resonating frequency of the eyeball and it has even been reported that this frequency can create visual disturbances.

2003年5月8日 · The frequency of eye vibration can be determined by adjusting the flicker frequency until the illusion disappears (i.e., until the difference frequency becomes zero). The same set-up can also be used to determine the amplitude of eye vibration, by adjusting the spatial separation between the two light sources until the oscillation appears to be ...

2016年8月1日 · This study was undertaken in order to clarify the effects of infrasound on vestibular functions by comparing observations of eye movement under exposure to infrasound and audible noise. Twenty-five healthy males were exposed to a wide octave-band noise, (approx. 125 Hz to 4kHz) or to 16 Hz or 5 Hz at 95 dB for 3 minutes.
