Popis: A research team conducted a study at NASA Dryden Flight Research Center to compare the perception of real versus simulated booms. The field test included an assessment of noise measurement systems and a subjective jury trial on perception of sonic booms heard outdoors. Seventeen sonic booms were recorded under the flight path of four separate flights of three F‐18s, using various microphones and recorders at multiple ground and ear level locations. Waveform analysis was conducted comparing the recordings as a function of location and measurement system. Eighteen subjects listened to live sonic booms, then rated the realism of the playback of a selection of those booms reproduced in the Gulfstream Supersonic Acoustic Signature Simulator II several hours later. The subjects also provided adjective descriptors of boom perceptions. The booms selected for the jury trial presented a variety of boom characteristics that included postboom noise. The subjects rated the playback as realistic, contributing to the va...
