The old experience in the field of soundproofing in all sectors of activity has enabled the development of predicting acoustic calculation software capitalizing on the expertise of human resources of ITS.

ITS is thus equipped with means of simulations suitable for the most common and other more complex acoustic computation and prediction issues.

  • useful for various phases of projects including: diagnosis of a situation in terms of acoustic, search for solutions in relation to a situation in terms of acoustics
  • founding the crucial phase of projects that is the performance of soundproofing equipment sizing sheets
  • allowing the selection of products and construction systems optimized with respect to the data and constraints taken into account and to the objective of result in terms of acoustics

The means of simulation of ITS are the basis of technological choices the most appropriate to the considered situation and base the acoustic guarantee that is attached to the supply of soundproofing equipment, their installation or the execution of acoustic insulation .

Most of the software allowing acoustic predicting computation at ITS have been developed internally, which allows the integration of experience data complementing the best theoretical approaches of all times carefully selected in order to base the simulation models.(1) (2) (3) (4)
