WHY DO R&Ds ?

Since its inception, the Gamba group has been involved in Research and Development in many areas of acoustics and vibration, to satisfy several needs:

  • to remain at the highest scientific and technical level for our acoustic and vibration engineering activities; this mainly involves developing new methods and calculation tools by furthering our expertise, through self-financing or by presenting projects eligible for public funding, particularly European funding;
  • to satisfy the expectations of our clients and partners for their requirements.

A RESEARCH METHOD

We are specialised in the design of innovative systems integrating acoustics, using an iterative approach.


A SUITE OF ACOUSTIC SOFTWARE PROGRAMMES

Software programmes that communicate with each other and with the user.

Our software solutions are designed to work together to create a data processing chain.

EFFECTS OF NOISE AND VIBRATIONS ON PEOPLE

PROPAGATION OF VIBRATIONS


R&D AND WOODEN CONSTRUCTION

The acoustic and vibratory behaviour of wooden buildings is one area in which we have invested a lot in recent years, in order to be able to offer services for better forecasting without over-dimensioning and thus support wooden projects (vibrations, airborne noise and structure-borne noise).

OUR DAILY MISSIONS

Acoustic and vibratory characterisation of materials, simulation of the acoustic and vibratory performance of construction systems and rail transport systems, development of dedicated models and software, and assistance in the development of industrial products and appliances are part of the daily work of our teams of engineers and PhD students.

Over the last few decades, we have launched number of internationally recognised tools, such as AcousPropa, AcousSting and AcousStiff. Other tools that we reserve for our own use, are continuously developed and allow us to propose innovative missions, in particular the generation and treatment of railway vibrations at their source and in buildings (dBTrack, Siprovib, Biovib). Furthermore, we rely on market tools such as Mefissto and Ansys for finite element modelling.

2D modelling of the propagation of an impulse wave in a room using the finite difference method in the time domain. Two sides of the room are equipped with a Schroeder diffuser (QRD, N=59) and the other two sides have an anechoic termination. The wave encounters a human head represented by an ellipse positioned between the points REC L and REC R.
