Acoustic Propagation Characteristics of Acoustic Logging Instrument

Shiyou jixie, 2016
Most of the shells of the sonic logging tools in domestic are the results of imitation,which are unable to predict the sound insulation performance before manufacturing.To develop a shell with better sound insulation performance,the sound propagation ...
