Predicting aerodynamic noise from industrial process control valves is no easy task.

In many installations in the chemical industry and in some power plants, aerodynamic noise is emitted by control valves in various industrial processes.

This noise is partially transmitted through the walls of the valves and also (and mainly) propagates downstream of the valves, being then transmitted by the pipes walls of networks, of more or less complex geometry (depending on the site constraints)

1 Presentation of software SILDIS^® = Sound Impact Limitation: Design for Industrialized Solutions (several modules)

The prediction of performances of products and construction systems for noise control engineering often requires an approach whose nature is computationally intensive, making its application difficult for most acoustics practitioners. Several softwares have been developed by ITS human resource in order to make possible such a prediction without any computational effort from users...
