Site-specific acoustic, rooftop velocity, and window acceleration measurements during the NASA Artemis II launch.

Acoustic, rooftop velocity, and window acceleration measurements were obtained during the NASA Artemis II launch at community sites 26-27 km from LC-39B. The instruments were not co-located; observations are site-specific. The acoustic record peaked at 104 dB re 20 μPa (1-s overall sound pressure level); roof-mounted velocity peaked at 2.08 mm/s; and at a residential site, a glass-mounted accelerometer recorded a distinct out-of-plane response near 7.3 Hz, with peak acceleration of 0.36 g. All three showed peak energy in the 2-20 Hz band, identifying a building-component response not captured by conventional community-noise metrics.
