About us

Viginoiz is a subsidiary company entirely owned by Bruitparif, a non-profit organization commissioned by the Île de France region to monitor noise pollution in the Parisian area.

The mission of Bruitparif is to democratize urban noise monitoring and to provide local authorities with effective means to fight against noise pollution. After meeting a great success, we decided to offer our solutions to actors outside the Paris area, and that is why we created the subsidiary company Viginoiz. It is through this subsidiary that we market our products. We offer different solutions to monitor efficiently sound levels in urban areas and alert drivers whose vehicles are excessively loud, and eventually fining those who break the law.
