Abstract
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.
