Reply to comment by manicdee33 in ‘We found the Artemis-I noise level at 5 km had a crackling quality about 40 million times greater than a bowl of Rice Krispies.’ — Maximum noise measured during Artemis-I launch on 16 Nov. 2022 was higher than predicted by marketrent
In this figure from that paper, while the flat peak is 120 dB centred around 20 Hz, with an A-weighting this only translates to about peak 95 dBA around 200 to 1000 Hz.
Measurements for occupational safety are done with A weighting, but would there be any safety concern with an unweighted 127 dB SPL at 20 Hz? or is A weighting still sufficient ?
Edit: higher res figure
