  We extract the excitation energy scales of the hadron spectra in a less
model-dependent method using Schottky anomaly. Schottky anomaly is a
thermodynamical phenomenon that the specific heat of a system consisting of a
finite number of energy levels has a peak at finite temperature due to the
energy gaps. Using the masses of all hadrons that are experimentally
established, we obtain the excitation energy scales of the hadron spectra and
investigate their flavor dependence.
