Supersonic aircraft produce a sonic boom when flying fa-ster than the speed of sound. In order to rule out detrimen-tal effects for inhabitants of overflown areas, civil super-sonic flights (like the Concorde) were allowed to fly overwater only. Due to progress in aircraft design, the super-sonic boom may be reduced considerably in the future.Such low sonic boom signatures will potentially be quieterand sound very different compared to conventional sonicbooms. For an assessment of human responses to low so-nic boom signatures, a sonic boom simulator has been builtat the University of Oldenburg. Listening tests were car-ried out in the simulator and volunteers rated the loudnessand the short-term annoyance of a variety of simulated andrecorded boom signatures, differing in the shape of the ti-me signal, the maximum overpressure and the A-weighted sound exposure level.
