Sound insulation is at the core of ITS activity, often involving on-site measurements of sound levels and of indicators related to the acoustic quality of buildings calculations for noise impact prediction and for sizing of soundproofing equipment, which are marketed by ITS, with or without installation.
Problem solving related to the exposure of workers to noise is one of the aspects of this activity, particularly in connection with corrugated cardboard production lines, rotary presses, machines related to metal processing (among which: presses for the automotive industry). Enclosures, noise barriers, cabins and soundproofed workshop offices are then soundproofing equipment frequently considered by ITS for the improvement of the conditions of professional activity.
In addition, taking into account the necessary tranquility of the residents around an industrial site often motivates the recourse to ITS. Soundproof buildings, canopies, silencers, noise barriers, insulation systems for pipes (including valves) are then structures for the design and construction of which ITS participates.
In particular, the energy production sector (thermal, particularly based on the use of engines or turbines and boilers in the case of cogeneration installations) combines these two contexts and therefore constitutes a field of activity of choice (related equipment is also marketed by ITS e.g. air intake filters, chimneys, exhaust gas catalysis devices).
Still in relation with the industry (sometimes also for universities or engineering schools), ITS intervenes in the context of projects of soundproof test benches and sound measurement rooms (including aeroacoustic wind tunnels) ; in addition to issues related to the propagation of noise (from the inside to the outside if it is a question of limiting the impact on the environment, including contiguous spaces within the same building or in the other direction if it is a question of obtaining a sufficiently low level of background noise within a space dedicated to acoustic metrology), the challenge is often to reproduce indoors (i.e.in an enclosed space) sound propagation conditions as observed outdoor i.e. in free field conditions: the anechoic linings of such deaf chambers are very specific.
In addition, aside from industrial applications, the acoustic comfort of buildings, and in particular the limitation of the transmission of external or internal noise and of equipment noise, are essential concerns in the context of projects related to the acoustic quality of a building such as an educational, spports or health institution, an office or associated spaces (e.g. meeting room, canteen). ITS contributes to such projects (new or retrofitted) in the field of sound insulation (ITS is also able to manage the limitation of the reverberation of these premises).
More generally, ITS often intervenes for the limitation of the sound production of turbomachines: not only the (large) gas turbines in power plants, or the industrial compressors (of large capacity) for gas liquefaction or air separation plants, but also fans and refrigeration units in the great diversity of their industrial applications, for the tertiary sector when they are not quasi-domestic (extractors, aerocondensors, heat pumps, air conditioning, ...).
ITS offers its sound insulation skills for all construction and renovation projects, industrial and non-industrial: "choice soundscapes, everywhere" is the slogan of ITS.
