OUR EXPERTISE
The design process of an acoustic product involves, at every stage, all the fields of expertise of R&D.
Understanding needs, researching materials, modelling and simulations, product design, testing, measuring and industrialisation.
At Boët stopson, all our products follow the same “design loop”.
During the design loop, we take into account various codes and standards in force to develop the products :
- PED 2014 68 EU
- ASME VIII
- ISO 11820
- EN 13445 : 13480
- CODETI / CODAP
- ISO 11691
Industrialisation : once the prototypes have been validated, we optimise our products and qualify them in their real operating conditions (pilot installation, final tests, etc.)
Simulation and modelling tools
We have constantly developed new acoustic simulation models: from the 1D analytical tools of the 1970s to the current 100% digital 3D models, we have always qualified and verified our products.
In the development phase, loops between modelling and physical verification are necessary. Test facilities allow us to make these measurements and to guarantee our customers the consistency and reliability of our products’ performance.
The welders are qualified and can meet the requirements of these different codes.
WPQR and WPS are necessary for the production of technically demanding equipment.

OUR TEST FACILITIES
We have simulation facilities covering all acoustic, vibratory, thermal and aeraulic phenomena :
- Engine test bench in real conditions
- Airflow test bench (to validate speed profiles and associated pressure drops)
- Impedance tube (KUNDT) : to qualify the absorbing materials used in our solutions
- Measurement of attenuation indices, absorption coefficients and noise levels of small equipment
- Imaging source location
- Studies of pulsating and vibratory acoustic phenomena in pipe networks.
- Studies of flexibility under pressure and thermal effects
