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.

Measuring Acceleration Due to Gravity
A simple pendulum can be described as a point mass and a string. Meanwhile, a physical pendulum is any object whose oscillations are similar to a simple pendulum, but cannot be modeled as a point mass on a string because its mass is distributed over a larger area. The behavior of a physical pendulum can be modeled using the principles of...
