Abstract:

The three main objectives of this study were as follows Determine the feasibility of investigating effect of simulated sonic booms on some sleep patterns of persons undergoing routine electroencephalographic EEG examinations determine the extent that EEG waveforms are altered by the simulated sonic booms and obtain disturbance, judgments as a function of the simulated boom noises. Results were obtained from fifty 50 subjects of both sexes with ages ranging from 15 to 72 years of age. Data was relevant to resting, dozing, or light sleep. The EEG waveforms for resting or dozing persons was not changed by the simulated boom noises. In general, the subjects were not, disturbed, by the simulated booms. Ninety-two 92 percent of the subjects reported no, disturbance, to any of the simulated booms presented. Two rise times of 15 and 7 ms were employed with overpressures ranging from 0.94 to 2.85 PSF.
