For many years, the performances of all our silencers and dampers have been tested in an independent laboratory. Thus, the data we provide are given in the strictest impartiality.
The CTTM performs all acoustic tests on our equipment : regenerations, pressure losses and attenuations of silencers.
We collaborate closely in R&D, especially for researches to improve the performance of our splitters and the NF ISO 7235 test standard.
CTTM has two coupled rooms, a semi-anechoic room and a reverberant room, where a wide range of experiments can be carried out under excellent conditions (very low background noise, large volumes, low frequency measurements,etc…). This rooms coupling of about 1000 m3 is unique in France.
