“…Very loud sounds, such as those near jet engines, were subsequently found to cause symptoms of vestibular activation. 2 For example, Parker et al 3 reported that 500 to 1000 Hz sounds induced visual field displacements in humans, which they attributed to nonlinear movement of the stapes in response to loud sounds, a phenomenon that they had shown in the guinea pig. 4 However, even loud air-conducted (AC) clicks fail to evoke eye movements with amplitudes larger than about 0.01 deg in normal humans.…”

Research into vestibular responses to sound has evolved in four stages. The first, largely the work of Tullio in the 1920s, involved inspection of the eye, head, and postural responses to sound of alert animals with surgical fenestrae into various parts of the bony labyrinth. The second, begun in 1964 by Bickford and his group and continued by our group and then by others in the last 10 years, involves the measurement of evoked myogenic potentials to air-conducted and bone-conducted clicks and tones in normal humans. The third, begun by Mikaelian at about the same time as Bickford and continued by McCue, our group, and others, involves electrophysiological recordings of primary vestibular afferent neuron responses to sound in anesthetized animals. The fourth involves measurements of vestibulo-ocular responses to sound in humans with the Tullio phenomenon. It was begun by Minor and his group in 1998 with the observation that sound-induced nystagmus in humans, the Tullio phenomenon, aligned with the rotation axis of the superior semicircular canal. They then showed a defect in the temporal bone between the apex of the superior semicircular canal and the middle cranial fossa, which was the cause of most, if not all, cases of sound-induced nystagmus. Here some of the key observations made in each of these four stages are reviewed.

“…Sporadic reports concerning this phenomenon subsequently appeared in the otological literature [3], usually involving patients with pathological fistulae due to middle ear disease or fistulae induced at operation as a treatment for Ménière's disease [4]. Particular concern arose with the development of early jet engines that emitted extremely high intensity sounds and it was noted that engineers involved in developing these engines frequently experienced disequilibrium and tilting of the environment [5]. Although sporadic reports of patients exhibiting the Tullio phenomenon appeared over the next four decades, little further research into its physiology was carried out until Brandt et al [6] reported the postural response of a patient in detail.…”

The Tullio phenomenon: a neurologically neglected presentation

et al. 2011

The Tullio phenomenon refers to sound-induced disequilibrium or oscillopsia. Patients with this condition frequently present to neurologists, many of whom are unfamiliar with the condition and its diagnostic criteria. Indeed, due to the unusual nature of the symptoms patients are often misdiagnosed as having psychiatric disturbances. Tullio patients describe disequilibrium, auditory and visual symptoms, which are recurrent, brief, and often triggered by loud noises or middle ear pressure changes, e.g. the Valsalva manoeuvre. Many cases are associated with superior semicircular canal dehiscence (SCCD). Early work suggested that the presence of sound-induced torsional eye movements and visual field tilts were consequent upon a utricular-mediated ocular tilt reaction. However, more recent evidence from imaging and oculographic research, as well as data from our patient series indicates that these ocular abnormalities are usually the result of superior semicircular canal stimulation. The clinical history and a focussed examination are often sufficient to make the diagnosis, which can be confirmed with high resolution CT imaging of the temporal bones. In some patients, surgical occlusion or resurfacing of the affected canal can ameliorate symptoms and signs. The aim of this paper is two-fold: Firstly, to review the clinical features of the Tullio phenomenon, and secondly, to highlight our own observations in three cases with a new clinical syndrome consisting of Tullio's phenomenon with bilateral vestibular failure, a pure horizontal nystagmus in response to sound, and no evidence of canal dehiscence.

“…Several authors have presented evidence that exposure to extremely intense noises (greater than 120 dB) may result in disturbing physiological effects in human subjects. Dickson and Chadwick [17] reported that persons subjected to jet aircraft noises of approximately 140 dB for moderate time 17.…”

“…High intensity noises in the infrasonic (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) and ultrasonic (16-20 kHz) ranges may cause extreme disruption of a variety of physiological processes, although little empirical evidence has been gathered to support this viewpoint. Kryter [28] speculates that extreme infrasonics may cause extreme amounts of ear pain, dizziness, nausea, and possibly resonant vibrations in the chest, throat, nasal cavities, and eyes.…”

Psychological deterrents to nuclear theft :

A review of the unclassified literature dealing with psychological deterrents was conducted for the Defense Nuclear Agency (DNA). Its purpose was to identify techniques that might be useful in DNA's Forced-Entry Deterrent Systems (FEDS) Program for psychologically deterring nuclear weapon theft. The review indicates that while human psychological processes (sensory, perceptual, and cognitive) can be manipulated by various means, definitive empirical data are lacking which directly relate to deterring nuclear weapon theft. Behavioral impact research should be undertaken by DNA to (1) ascertain the deterrence values of the many techniques identified and (2) test the hypotheses implicit in the FEDS concept.
