Query: Impact of infrasound atmospheric noise on gravity detectors used for
  astrophysical and geophysical applications   Density changes in the atmosphere produce a fluctuating gravity field that
affect gravity strainmeters or gravity gradiometers used for the detection of
gravitational-waves and for geophysical applications. This work addresses the
impact of the atmospheric local gravity noise on such detectors, extending
previous analyses. In particular we present the effect introduced by the
building housing the detectors, and we analyze local gravity-noise suppression
by constructing the detector underground. We present also new sound spectra and
correlations measurements. The results obtained are important for the design of
future gravitational-wave detectors and gravity gradiometers used to detect
prompt gravity perturbations from earthquakes.
