In a factory producing machines, engines on which technical checks are performed (e.g. endurance, requiring a specific test bench) is a very powerful noise source potentially causing sound nuisance for personnel operating in the vicinity as well as for the neighborhood. It is often necessary to use in such cases a very performing soundproofing equipment in order to ensure compliance of the installation on the one hand with respect to the legislation on noise at work and on the other hand with respect to the regulation in terms of environmental protection.

ITS will participate in the soundproofing of 4 test benches for combustion engines with high power output around Mulhouse (Alsace region, France).

Of course, the partitions constituting this soundproofing equipment will prove particularly important sound attenuation, for the envelope (walls, ceiling) as well as for doors and windows allowing a visual inspection of the tests. In addition, the removal of the heat dissipated by the combustion engines will necessitate the implementation of an efficient ventilation system with proper soundproofing device.

For such soundproofing applications, ITS sells specific products and construction systems, with or without iinstallation (in some cases, supervision of acoustic insulation work carried out on site by local assembly teams is possible).

Where necessary, the soundproofing of test benches proposed by ITS may include the implementation of interior linings to obtain free acoustic field conditions (most of the time, but not always: on a reflecting plane) if acoustic measurements are envisaged e.g. for characterizing engine noise emissions or in a research and development (R & D) context.

Sound level measurements on site (before and after works), engineering, turnkey realization: ITS can participate in all projects of construction or renovation of soundproofed engine test benches.
