Listening to your expectations

The performance, durability and reliability of your systems are often related to specific requirements in terms of acoustics and vibrations. Evaluating these aspects at the end of the development process or during qualification raises the risk of having to review designs and induces additional costs.

Right from the design phase, METRAVIB will assist your engineering team in taking these requirements into account as early as possible, so as to achieve the necessary performance objectives:

  • Mechanical resistance: vibration fatigue, damage
  • Geometric stability: microscopy, metrology, optics
  • Comfort: transport, electrical appliances, building
  • Safety: fatigue, structural damage, worker exposure

Our expertise is including field testing, structural dynamics or vibroacoustic calculations, as well as various technique applied to signal processing, measured data analysis and advanced algorithms in machine learning.

Our team of senior experts and experienced engineers will assist you in proposing the adequate approach to help solving each technical issue. The key to success relies on combining the understanding of physics and the application of the right method/algorithm.

With professional know-how and field proven expertise, METRAVIB is an unrivaled partner in the management of acoustic and vibration-related aspects from the design phases to your final product.
