Abstract:The study concerned the measurement of mood changes resulting from simulated sonic booms occurring during sleep. Subjects from three age groups (21 to 26, 40 to 45, and 60 to 72 years old) spent 21 consecutive nights in a sleeping room equipped for sonic-boom simulation. During the sixth through seventeenth nights, simulated sonic booms of 1.0 psf 'outdoors' overpressure level (.1 psf measured inside the the sleeping rooms) were presented hourly throughout each night.
As the measure of mood, the subjects completed a composite mood adjective checklist in the evening before retiring and in the morning after waking on each of the 21 days. No change in moods attributable to the occurrence of simulated sonic booms was found. Substantial effects relating to the age of subjects, irrespective of boom presentations, were obtained.
It was concluded that simulated sonic booms of such low intensity were unlikely to have adverse consequences on the mood states of most individuals.
