| Abstract: | Based upon pipeline acoustics, the common used isolating noise sleeve structures are initiatively studied in order to decrease the background noise during picking up sound signals. Furthermore, specially designed CAD software can be conveniently used for determining the sleeve structures in response to various kinds of sound transducers and different measurement cases. Effective results are proved in practice. |
