Findings from recent low-level sonic boom studies have shown that people's evaluations of startle could not be explained by loudness only and the startle evaluations were correlated strongly with evaluations of annoyance. A pilot study was conducted to examine how changes in physiological responses (skin conductance, pulse rate, and EMG) compared with subjective ratings startle. Analysis of this data was difficult because the intervals between stimuli were not long enough for some of the physiological measures to return to baseline before the next stimulus exposure. In addition, repeatability of responses was difficult to measure because of the complexity of the test which involved the subject doing several tasks while being exposed to the sounds. To examine what level of physiological response repeatability can be expected in these sonic boom experiments, another test was conducted in which subjects were exposed to simulated sonic booms. The interval required between boom exposures necessary to return to baseline was also examined. To examine the day-to-day repeatability of these measures, each subject completed several sessions on separate days. The variations in physiological responses within and between subjects will be described along with the trends observed related to signal characteristics. |
