  In this work, propagation of acoustic waves in a one-dimensional binary chain
with different types of correlations in elasticity distribution is studied. We
applied entropic analysis to investigate and quantify the
localization-delocalization transition in long-range correlated chains in terms
of the scaling exponent $\alpha$ and discuss its relation to the order-disorder
levels in the structure of the chain. The results demonstrated that the
entropic consideration detects correctly the critical value of $\alpha$
separating localization from delocalization bands.
