The diagnosis of a situation in terms of acoustic by ITS is based on a long experience of confrontation with issues having a wide variety (but occurring with some repetition) in relation to acoustic insulation.
This diagnosis may include examination of manufacturer drawings and data, or analysis of acoustic measurements made by others if they are already available: ITS can take over studies performed by control offices or engineering teams either specialised or not (ITS is not intended to compete with them) and particularly action plans performed by others. If needed ITS can perform (promptly) complementary sound records (possibly with spectral analysis) to quantify the noise emission of an equipment or characterize the performance of a construction. ITS can perform other statements and investigations on site (site conditions, accessibility, operating constraints, environment ...).
This task may necessitate the performance of acoustic measurements analysis reports (for measurement performed by ITS or not) or of acoustics calculation sheets: cf. below in the same page.
With respect to such missions performed on its own behalf, ITS has taken out an "overall designer" insurance including notably the operation civil liability insurance, the professional civil liability insurance, and the compulsory insurance of decenal liability.
From the diagnosis of a situation in terms of acoustic by ITS it results an exhaustive explanation of the data taken into account, as well as of various related constraints and a performance target in terms of acoustics appropriate to the considered situation for avoiding acoustic nuisance.
