The aim of the collaborative project is to further develop the company’s “QUIETPRO®intelligent earplug” technology, which has already been adopted by military forces all over the world, for example by the US military and NATO, as well as in Scandinavia.

The earplug, which was originally developed by SINTEF ICT, has been commercialised by Nacre, which was sold to the French-American Sperian group in 2007, but is still headquartered inTrondheim.
The earplug incorporates a mini-loudspeaker and internal and external microphones. In quiet surroundings the earplug “opens”, and the wearer can hear quite normally. When the noise level rises, the device filters out the noise as such, while speech is allowed to pass. Used in conjunction with any radio system, QUIETPRO® is a complete communications terminal for noisy environments. It operates just as well in the engine room of a ship or on board an offshore platform as in a military vehicle.
Adapted for use offshore
Hearing loss caused by high noise levels is one of the most common work-related injuries in the world. Workers on offshore platforms and other extreme work environments are exposed to extremely high noise levels and are at risk of completely losing their hearing, and Statoil aims to do something about the situation.
QUIETPRO Offshore will measure the dose of noise received by the individual operative and emit a warning signal when the upper threshold for noise has been reached and the user should leave the area. The system will also give Statoil unique insight into the actual burden of noise borne by its operatives. Development of the civilian version of the earplug is already under way, and a pilot version will be ready by the end of the year.
Much of the development of this first civilian version of QUIETPRO® took place as part of the SoHOT project, a User-guided Innovation Project (socalled BIP) financed by the Research Council of Norway and Statoil.
