  Solid state detectors and cryogenic detectors are widely employed in rare
event searches, such as direct Dark Matter detection or Coherent Neutrino
Nucleus Scattering experiments. The excellent sensitivity and, consequently,
their low energy thresholds are among the most appealing features of such
detectors. We present a method to quantify the lowest trigger threshold
achievable as a function of the acceptable amount of noise events triggered for
the physics case under investigation. We then apply this novel method to
existing experimental and simulated data to validate the model we presented.
