Theoretical considerations and experimental evidence suggest that otoacoustic emission parameters may be used to reveal early cochlear damage, even before it can be diagnosed by standard audiometric techniques. In this work, the statistical distributions of a set of otoacoustic emission parameters chosen as candidates for the early detection of cochlear(More)
Perception of the subjective visual vertical (SVV) is mainly based on the contributions from the visual, vestibular, and proprioceptive systems, and participates to the process of spatial orientation in relation to the surrounding environment and to the gravito-inertial force. The SVV can be significantly influenced by the presence of a displaced visual(More)
Thirty-eight patients with known unilateral cochlear hearing loss at 6 and/or 8 kHz were examined for transient evoked otoacoustic emissions (TEOAEs). These findings were compared with those of the contralateral "normal hearing" ear. Statistically significant lower values of echo reproducibility and amplitude were recorded in hearing-impaired ears, together(More)
The relationship between hearing loss, detected by measuring the audiometric threshold shift, and the presence of long-lasting otoacoustic emissions, has been studied in a population of 66 adult males, by analyzing the cochlear response in the 80 ms following the subministration of a click stimulus. Most long-lasting OAEs are also recognizable as(More)
Time-frequency analysis of the transient-evoked otoacoustic emission response was performed on a population of subjects affected by sensory-neural hearing loss characterized by a sharp audiometric profile, caused by firearm noise exposure (42 ears), and on a control population of normal-hearing subjects (84 ears). Time-frequency filtering permitted a(More)
Pensacola Simulator Sickness Questionnaire (SSQ) is a valuable method to analyse symptoms evoked by exposure to a flight simulator environment that can also be adopted to evaluate the effectiveness of preventive tools, aiming at reducing simulator sickness (SS). In this study we analysed SSQ data in subjects undergoing a standard ground based spatial(More)
This study was aimed at evaluating the time course of auditory steady-state response (SSR) variations during two consecutive exposures to hypobaric hypoxia. Six normal subjects were examined in a hypobaric chamber at ground level. Then, they climbed to a simulated altitude of 17000 ft (5182 m), where SSRs were recorded after 6, 12, 18, 24 and 30 min.(More)
Transient evoked otoacoustic emissions (TEOAEs) have been analyzed in a population of 134 ears, divided into three classes: (1) nonexposed ears in bilaterally normal hearing subjects, (2) audiometrically normal ears of subjects exposed to noise and affected by unilateral high-frequency (f>3 kHz) hearing loss in the contralateral ear, and (3) the(More)
The present paper presents a review of the literature on "hypoxia and human auditory mechanisms". It examines and discusses, above all, the results obtained in the various studies using pure tone audiometry and auditory evoked potentials. At the present time, the two areas which appear most sensitive to hypoxia are the cochlea and, above all, the(More)
Auditory brainstem responses (ABRs) were recorded in six volunteers before, during and after 90-min exposure to hypobaric hypoxia (5,184 m; barometric pressure = 405 mmHg) in an altitude chamber. Waves I, III and V absolute and interpeak latencies were analysed. The main result of the experiment was a significant shortening of the brainstem transmission(More)
