Test results are presented on the response and behavior of automobile drivers subjected to sonic boom disturbances under actual driving conditions. The design and development of a portable sonic boom simulator, auxiliary equipment, and experimental techniques are used to study the nature and severity of the disturbance effects. The sonic boom simulator consisting basically of loudspeakers and a function generator was mounted inside a test vehicle. It was able to produce sonic booms that were very similar to what drivers would experience following SST overflights. The simulated booms had overpressures of 3 psf, rise times of about one millisecond, and durations of 100 milliseconds. Two aspects of driving were investigated the tracking manoeuver and the stopping task. Results from both tests indicated that driver behavior was not affected by the simulated booms, even though some drivers considered it annoying or disturbing. It may therefore be concluded from present limited statistical tests that current commercial supersonic aircraft under normal flight conditions (without superbooms) would not produce adverse effects on a driver's stopping distance or his ability to follow a particular course.
