Welcome to the website dedicated to acoustic software


AcouS PROPA® is software for modeling acoustic propagation indoors and outdoors. Our program is a modular tool that meets the needs of each user. Whether it is an industrial project, a environment project, a wind farm and room acoustics,  AcouS PROPA® calculates noise maps and also allows the calculation of spatial decay and sound decay time.

Our organization provides inter-company training in Paris or Toulouse, and in-company training on request in France and abroad on the use of our AcouS PROPA® software.


AcouS STIFF® is software used for predicting the sound reduction index. Our program complies with ISO 717-1, NFS 31-051 and ASTM-E413 standards. In addition to our tutorials, our team teaches you how to use the AcouS STIFF® software.

Our inter-company training courses take place in Toulouse and Paris but can also be carried out in your offices on request anywhere in France and abroad. They teach the participants the basics that will serve to highlight the influence of the parameters that can be used to optimize a structure.


AcouS STING® is software used to predict the level of impact noise. Our software complies with the ISO 712-2 standard and is the software suite associated with AcouS STIFF®. The shock noise level is the second relevant criteria for evaluating the acoustic performance of a simple or complex floor. Graphs and/or tables will illustrate the results.

The AcouS STING® software is the most effective simulation tool for impact noise level improvement. Training courses take place inter-company in Toulouse and Paris and also in your company offices on request, anywhere in France and abroad.



DIAG.Lexd® is the best designed risk prevention software for noise exposure. This software makes it easy to diagnose workers' noise exposure. It complies perfectly with the EN ISO 9612 standard, the Lex,8h calculations are carried out taking into account the LAeq, Ti (measured equivalent continuous levels) and the peak values with the percentage of PPE usage (personal protective equipment).

It is aimed both at experienced specialists and at people with no particular skills in acoustics. This tool can be used by prevention departments as well as health and safety or occupational health departments. 

Just like our other software, GAMBA provides inter-company DIAG.Lexd® courses in Paris and Toulouse and also in-company on request, anywhere in France and abroad.






Since the 70's, GAMBA Acoustique has been engaged in research and development applied to all areas of acoustics, such as sound propagation in enclosed spaces and open environment, the acoustic behavior of materials and the transmission through the walls or the effects of noise on man and sound environmental management.

The results of this applied research and our experience in acoustic engineering have enabled us to develop and validate 4 families of reliable and efficient software for forecasting and analyzing sound, available in French and English.

This software is intented for all actors and stakeholders such as engineers, design offices, acousticians, architects... who are affected by problems related to acoustics in the fields of industryconstruction or the environment.
