MITHRA is a powerful computer-assisted design software based on an unusual method of modeling the trajectory taken by Sound between buildings and various kinds of transport infrastructures such as roads, railtracks, etc.

Mithra offers the Possibility of predicting noise levels near high| ways. IL can draw up sound maps and optimize the use of various | kinds of sound-proofing, such as Screens, coverings, etc. It takes into account each side in all its complexity: topography, buildings. roads, traffic, etc. and determines the multiple pathways that sound takes in order to move from a railway track or highway to a This software is based on a rapid algorithm for identify acoustic trajectories between a sound source and receptor in an complex urban setting it is based on an inverse method of tracking rays the major trajectories are represented by the direct rays Defected or reflected (by the ground are vertical facades) or by the combination thereof. As a result of not being limited in order of reflections and diffraction the algorithm is well suited to predicting the amount of sound experienced along a highway as well as in closed network in an urban setting with heavy Constructions in an open setting with vast spaces between field building or even in mountains areas.
