1. A method, comprising:
disposing an acoustic logging tool in a wellbore;
broadcasting a shaped signal with the acoustic logging tool such that the shaped signal interacts with a boundary of a casing and a material;
recording a result signal from the boundary with the acoustic logging tool;
identifying a cut-off time to be applied to the result signal;
transforming the result signal from a time domain to a frequency domain;
selecting one or more modes sensitive to a bonding at the boundary between the casing and the material;
computing a decay rate of the one or more modes that were selected based at least one or more decay curves; and
converting the decay rate to a bonding log.
