Comparison between the target signals (N-wave like booms, in dotted black) and the measured signals (in solid red) at the door F3 between bedroom 3 and the living room, generated by simulator 3. Top: low boom signal 6. Bottom: high boom signal 7. Left: temporal waveforms. Right: frequency spectra. Measured spectra are noisier and decay much slower in the high frequency limit. Lower curves in light grey show ambient noise spectra measured during 2 s.
