SONIC BOOM EXPOSURE EFFECTS--A FIELD STUDY ON HUMANS AND ANIMALS

A field experiment was undertaken to study the reactions of humans after exposure to sonic booms with special reference to startle reactions. In addition, animals in the vicinity of the test site were observed and the extent of annoyance reactions in a community near the test site was determined. The results show that the presence of startle reaction in an individual is not correlated to boom levels studied. The number of reactants in a group, however, exhibits a dose-response relationship with boom levels. The results also indicate a masking effect of background noise on the extent of the reaction in a group and a tendency to habituation after about 10 exposures. The old age group reacted less than the young age group studied, but this could be attributed to differences in the hearing status. In the exposed community where the boom levels were much lower than at the test site, annoyance reactions were low. The reactions among animals were small with slight startle responses among all species studied. A strong habituation effect was observed.
