The influence of age on the auditory brainstem responses (ABRs) of 39 normal infants (aged less than 6-18 months) and children (aged 19 months to 3.5 years) was investigated. While the ABR threshold of infants (mean value: 9.3 dB nHL) is still slightly higher than that of normal-hearing adults, children show a distribution which corresponds approximately to(More)
A haptic device using flexible sheet such as rubber has already been proposed. Controlling the bias tension of the sheet, the device varies compliance of the sheet in the normal direction; users can feel compliance of various virtual objects if they touch the sheet. This device is integrated into a visual and haptic display. The haptic device uses(More)
A random sample of 15 patients suffering from multiple sclerosis without acute episodes and at least partially able to work, shows to a high degree of statistical certainty that reduction in amplitude of acoustically evoked brain stem potentials (BAEP) is closely linked with beta-weighted performance value of the square search test (QSP).
The differences between amplitudes and latencies of acoustically evoked potentials (AEP) in children, aged between 3 and 7 years, were tested using random distributed stimuli with mean interstimulus intervals (ISI) of 1.45 sec, 2.1 sec, and 4.1 sec and periodic stimuli with the same ISI. We applied three different intensities, 30, 50, and 70 dB SPL and a(More)
