I've been using the MITHRA-SIG software since 2010 for various research projects aimed at highlighting the link between exposure to environmental noise in an urban environment and human health (neuro-cardiovascular and maternal-fetal pathologies, well-being, school performance, etc.).
GeoMod (an attentive, accessible, close-knit and willing team) has made a lot of progress with the software, which is now very efficient and ergonomic. I really appreciate their technical support, always ready to listen and constantly adapting to changes in regulations to incorporate the latest acoustic calculation methods!
