Zusammenfassung:The invention relates to removing ring down effects from sonic waveforms. An illustrative acoustic range finding method including deploying a tool downhole, transmitting a first acoustic waveform with a transmitting acoustic transducer of the tool, receiving a second acoustic waveform with a receiving acoustic transducer of the tool, removing a deterministic waveform from the second acoustic waveform to obtain an echo waveform, and deriving a measurement from said echo waveform.
