Project Summary
Vox Aeris is developing an acoustics based system to
reduce exposure to particulate matter from rolling stock in
undergound railway networks for the beneft of passengers
and staff. Ventilation systems are difficult to upgrade, high
grade filters are costly to operate, and certain stations
and rolling stock may not even be equipped with filtration
systems. The new system is designed to increase pollutant
capture efficiency while reducing energy expenditure;
allowing easy retrofitting
