More than 50 years of expertise in
Acoustics, Vibration, Material Testing and Durability.

We are in constant interaction with all industries since 1969. Most involved in the development of silent submarines until the early 80’s, METRAVIB has always be a privileged partner of the defense and aerospace industry, extending then tight connections with the energy, oil and gas, automotive and railway industry as well, bringing valuable solutions to improve products performance when it comes to noise and vibrations.

Significant contributions are also noticeable to the Aerospace and Defense industry, such as the development and operational qualification of shock absorbers, vibration control tools, and a contribution to the improvement of the acoustic comfort inside vehicles and airplanes.

The origin of METRAVIB DMA comes from…
acoustic engineering and the French Navy!

One of the very first DMA worldwide has been developed in 1969 by METRAVIB to address the Engineering group needs of characterizing viscoelastic properties of the polymer materials used to reduce the noise generated by military submarines.

From this original prototype METRAVIB  became aware of the importance of viscoelastic properties for the industrial products performances and  for the development of advanced materials.

Since 1969, METRAVIB is working in close cooperation with leaders of Polymer & Rubber Industry to develop testing instruments and methods meeting the expectations of scientists, compounders, research & development engineers.

This has led METRAVIB to offer a unique range of instrument featuring the most advanced scientific design in dynamic mechanical analyzers and covering extremely large analysis ranges of frequency, force, strain and temperature.
