Human equilibrium during acoustic stimulation by discrete frequencies. AMRL-TR-68-7.
The ability of subjects to balance on narrow rails was measured during exposure to pure tones of 100. 260, 500, 1500, and 2500 Hz and a control condition. One group of subjects was presented the test stimulus at intensity levels of 95 dB (re 0.0002 dyne/cm) in the left ear and 75 dB in the right ear (asymmetrical exposure). The other group was presented the tones at a level of 95 dB in both ear...
متن کاملVehicle Cabin Noise Simulation due to High-frequencies Stimulation
In this paper, the acoustic environment in a vehicle cabin under the influence of highfrequencies aerodynamic sources has been studied. Some panels on the windshield, the roof, the doors, the front pillars, and the floor of a vehicle simulated as input source of noise when the car is moving at high speed, i.e. 112 km/h. The status of vehicle cabin in each of these modes has been studied and com...
متن کاملAcupuncture: neuropeptide release produced by electrical stimulation of different frequencies.
Brain functions are regulated by chemical messengers that include neurotransmitters and neuropeptides. Recent studies have shown that acupuncture or electrical stimulation in specific frequencies applied to certain body sites can facilitate the release of specific neuropeptides in the CNS, eliciting profound physiological effects and even activating self-healing mechanisms. Investigation of the...
متن کاملPhase-locked loop for precisely timed acoustic stimulation during sleep.
BACKGROUND A brain-computer interface could potentially enhance the various benefits of sleep. NEW METHOD We describe a strategy for enhancing slow-wave sleep (SWS) by stimulating the sleeping brain with periodic acoustic stimuli that produce resonance in the form of enhanced slow-wave activity in the electroencephalogram (EEG). The system delivers each acoustic stimulus at a particular phase...
متن کامل[Changes in human spontaneous otoacoustic emissions with contralateral acoustic stimulation].
According to current cochlear concepts, spontaneous otoacoustic emissions (SOAEs) are thought to be the product of outer hair cell (OHCs) movement. Furthermore, efferent neurofibers from the olivocochlear bundle primarily innervate OHCs. Thus, we designed this investigation to determine changes in SOAE under conditions of contralateral acoustic stimulation. Fouty-two normal ears of 34 subjects ...
